Hairfinity

I could really rip apart the Hairfinity clinical study but I don’t want to. I want smaller companies to continue to do experimental work to substantiate their claims and having a third party like myself denigrate those efforts is counterproductive.  I also understand the cost of making a good scientific study and that it can be more than what a small company can afford. If this was a University-led study or a large company like L’Oreal, there would be no holds barred in my critique. This is as gentle as I can make it.

The ingredients

The ingredients label lists a variety of common vitamins with substantially above recommended daily intake of the B vitamin family. B vitamins are known to be essential for a variety of biological functions including increasing cell numbers and cell growth. Although it is not something you can see obviously, hair is composed of cells and hair growth means increasing cell numbers and cell growth. Will high levels of B-vitamins increase hair growth? This is unknown. However, as B vitamins are water soluble, you should expect to see the excess passing out in urine.

The active ingredient is listed as capilsana complex which is defined as a mix of MSM (methylsulfonylmethane) and hydrolysed collagen.

Important: Please do not substitute this general information for a doctor’s advice. Do not take this pill if you are pregnant or intending to fall pregnant as it has high vitamin A levels. Collagen is an animal derived protein so if you are vegetarian or if you do not eat some types of meat for religious reasons, this pill may not be for you. Due to the above average B vitamin levels, your water intake should be increased. If you are on a low protein diet or have kidney problems, consult your doctor first.

The  reason for the clinical study

In the clinical study report, MSM is highlighted as a key ingredient of hairfinity pills. Hairfinity states that MSM has potential to increase the hair growth phase but this has yet to be shown clinically, hence there is need to do the clinical study.

Analysis of the study

The reporting of the study is very poor for a variety of reasons which I will list. The impact of this is that I cannot say whether or not it was a good study and importantly whether or not the results of it are valid.

Here are the issues:

1. There is missing data

For example, hair length measurements  to assess hair growth are taken after 15 days, however, the graphs show only a single measurement every 30 days. It does not make sense to me. Should I double the number to get the monthly growth? If I do, then the growth rate would be astronomical – about 1.25 inch per month without the supplement and going up to 2-3 inches per month with the supplement. If I do not double the 15 day measurement, the numbers are still grand – 0.75 inches per month without the supplement and 1-1.5 with.  Is this real?

2. The study does not mention any controls

In science controls are everything. In order to know if the effect of hair growth is only from the pill and not from other factors (e.g change in weather, diet etc.), it is necessary at the very least to have a comparison group who do not take the supplement throughout the 90 day study period. This instance was not reported.

3. The study has only 25 participants

This is a very small group; which is not ideal, but more importantly, the gender, age, ethnicity, nutrition, activity level etc of the participants is not mentioned. These are all important factors to judge how biased the study was. It is not accurate enough to mathematically calculate bias with just 25 participants (Yes, you can calculate bias!).

4. The study does not mention which part of the head was used for hair growth measurement.

We know that different parts of the scalp can grow at different rates so a direct comparison needs to be done from the exact same location. This is not directly mentioned.

5. The method used in the study to measure hair growth length may not be good enough.

The usual technique  in hair growth studies is to shave a small section of hair to the scalp and then record hair growth from the scalp. This eliminates issues like hair breakage due to combing. The method used in the hairfinity study is a hair dye method in which existing hair is dyed and hair growth is then measured from the scalp to the dye mark. There is a large potential for error with this method. Fading of the dye over time as well as being able to accurately measure from the scalp to the exact point where the dye is could both potentially pose a challenge when seeking to attain results.

 

There are many simple procedures that if properly implemented, could have improved the overall study. I would venture to say that a lot of the issues within the study arise because of  how the data was presented, which I think was for simplicity rather than accuracy. This is common when a scientist is trying to communicate a general message. If there is additional data, I would be happy to look at it and make a better assessment of whether the study results and the resulting claim that the supplement can increase hair growth are at the very least valid.

Do the studies done by product companies themselves hold a lot of weight for you in terms of your decision to buy?

Hi. Can I take these pills 2 every other day??

cea8519

worked for me. Made my face breakout so bad that I stopped taking them.

Tabatha

Everyone’s experience is different when it comes to any type of pill. for me it worked. It has helped me grow my hair. Before my hair was so unhealthy it was breaking off, it was always knotting and splitting it was BAD! I took hairfinity and it gave my hair the nutrients that it needed to grow and to be healthy. I’ve been using it off and on for 2 years and I haven’t had any issues when it comes to breakouts, but I know that there are some people that have. So for ME it works.

hairstar

You’re right, the first step to healthy hair is to stop the breaking off. Then you have to stop the shedding. I’m glad it worked for you.

saraa

Hasn’t work for me as I thought it would, so I will be trying manechoice once I finish my last bottle of hairfinity

Thank you for this article. As an analytical chemist myself I am very skeptical of this product. The clinical trial is a joke, and no certificate of analysis is issued upon request. Are they even doing any quality control? If so, what are the parameters. I looked for a patent for this product and it doesn’t even exist. Are they fulfilling the FDA requirements for nutraceuticals? So many unanswered questions? What about manufacturing? I hope it is being processed in a controlled cAMP facility. Anybody can purchase a tablet press, that doesn’t make you qualified to prepare it. These people… Read more »

Hello,

Do you know if that product had any control quality since your last message ?

I’ve used Hairfinity twice. In 2013, for two months; I saw about 3 1/2 inches and last year for four months but saw only about 3 inches. I really wanted it to help with my hairline after I had my daughter in 2013, I suffered post partum alopecia. It help with that some. But are they worth the cost; no. I’m using Nature’s Bounty hair, skin & nails gummies for $8. The jury’s still out because it’s only been a month but I’d rather pay $8 a bottle than $24 any day. And I got them BOGO free.
Jenell Stewart

I used them for 6 months and saw amazing results.

DShot

I have been using it for months and it has worked as far as I’m concerned. That’s how I tested it. Used it for 30 days then tried for 60. Now going for a 4 month cycle. I’ve been happy.

Shon
Let me say this first, this product absolutely works. Now, I tried this product for one month only and decided to stop using it because I started having abnormal breakouts about a week after starting the product. They were the big ones too, not a small normal pimple. I increased water intake hoping that that was my issue, I normally juice, eat veggies, and sometimes seafood and I didn’t switch that up. I eventually started taking them every other day until I was completely out of them to avoid shedding like some others who had side effects of this product… Read more »

Did it work?

Vee

Hmm some of these comments in favour of the product sound suspect.it’s like the company has got its interns to post comments. I take claims that promise to make your hair grow by popping a pill with a pinch of salt. No amount of marketing and celebrity paid endorsements is going to change that.

MercifulLove

Lol @interns, but yes I feel the same way….

Vintage
My hair normally grows 0.3inches per month MEASURED. with hairfinity after one month it was exactly 0.55inch growth. Which is average growth, yes but not my average growth so to me it was quite significant considering. I’m A science student too so I know that there needs to be control factors. I measured the front portion of my hair which is the fastest in growth only. I did not change ANYTHING in my hair routine however I had my hair in braids which doesn’t contribute to hair growth but does reduce hair breakage. However it was the growth I measured… Read more »
DutchGirl4C

Like…? Which other brands?

Raya

Biotin w/ 10000 mg work just as well. Take one a day, before bed with 4 oz of orange juice and you’ll see an increase in growth. Plus it’s more affordable too.

Ambi

I tried it for two months and saw no difference in anything. no negatives either but no increase in growth I had my regular growth that was fine, and didn’t see any increase in growth. Never had a problem with growth just wanted more growth/faster I’m now on my 3 month of Fast grow I think I like that better and after this I might try MANE vits

Jessica WT
For those who say they have had success with Hairfinity I would have to pose these questions: 1. Were you taking and daily multivitamins previous to starting Hairfinity? 2. Have you changed anything in your eating/dietary habits since taking Hairfinity? 3. Have you changed your exercise routine since starting Hairfinity? 4. What time of the year or season did you begin taking Hairfinity? 5. What was you hair GROWTH RATE like BEFORE starting Hairfinity? 6. What is your GROWTH RATE currently on Hairfinity? 7. Have you changed anything in your hair care regimen since starting Hairfinity? It would seem that… Read more »

I took hairfinity and still do … It works. For the first three questions you asked … The answer is no… I did not change anything not add anything. Also, I already drink a lot of water so that didn’t effect the result. The first time I took it, it was summer… But I’ve taken it random times since then. I usually do it for two months and stop for one or two. I can’t say what my growth rate was before it after but u do know this… The first time I took it, within two weeks my hair… Read more »

i cant get a clear understanding from the study that was done, bottom line does it work or not? i wanna know before i buy.

Lele76
Not sure if you brought Hairfinity yet. But, I have tried them and they work. Only I just hate having to order and wait on a product. Plus not to mention the price. I happen to see a commercial on the product (see attaché I picture). I did some research saw that the person compared the product to Hairfinity. So I decided to purchase the product. It was very cheap in price. The results were very evident. My hair grew fuller and longer. Even my stylist noticed. I do wear my hair in protective style. You can pick these up… Read more »
Raya

LOL, Yes the do. Drink plenty of water to get it working thru your system and intake more fruits and veggies.

trublkbeauty

I’ve tried a two months supply it worked! Two inches longer in two months. I normally have very thick course hair . After hairfinity I had a see threw afro. Never again.

NaturallyLovenMyHair

Thank you for you analysis. I took Hairfinity Vitamins for three months after reading all of the rave reviews.Perhaps I didn’t take it long enough for my hair because I did not experience a significant difference in growth. I may try them again for a six period to see if there is any change.

NaturallyLovenMyHair

Oops, I meant your analysis 🙂

Jackie

I started my second bottle of Hairfinity last week. Results from the first bottle are: thicker hair, longer hair, the return of my edges which have been MIA since 2004. I love the product.

Sammie

Add me to the list as one of the participants, cause I have used Hairfinity for over a year and with only one set back, my hair grew healthy and I for one could say yes it works, I’ve seen length and shine.

Gemma

Love this step-by-step assessment of the methodology whilst being respectful to the company. Well done!

Jumoké
How ironic I just did a video about my experience with biotin (still working in it. Check back on my blog, jumibearz.weebly.com, for more updates). I was interested in buying Hairfinity/Manetabolism but I had to do some heavy research before I jumped the bandwagon. A quick scan on the ingredients and I saw that it mostly compromises of MSM and biotin. I did my research on MSM and was scared of the side effects (I’m serious; look up MSM side effects on google and see what comes up). Biotin on the other hand, I didn’t hear so much negatives except… Read more »
Kweenie

Too many people on here are responding to the discussion of the article with their own anecdotal experience. You have every right to *believe* they work for you, but that is not the same as the missing empirical evidence the writer is talking about.

June

A lot of them are paid to come online and counter bad reviews. Some are better at guising their role than others. Be very mindful of any information you read.

Renee

I can only write about my experience, I saw no difference. I will say my nails appeared to grow longer, but that happens whenever I take vitamins. Hairfinity out, multi-vitamin in

Dananana

Hmmm…$96 for 4 months would be enough to cover a gym membership in some places, depending on how often one works out. I personally feel that being active and eating healthier have done more for my hair than biotin or any other supplement ever has. My hair has grown sooo much in the past year just from eating more vegetables and getting off my butt for a few hours at least twice a week. Plus, by working out, I’m taking care of all of me instead of just my hair. But to each her own, I guess.

Youngin girl
I’m at the large gym sitting in the bleachers reading this to kill time and my Civics/Econ classmate came up to me to say Hi and what I’m doing. I told her I’m reading the hair vitamin thing and she asked,”Hairinfinity?” I said,”Yeah” she told they really do work and it makes your hair grow because she said it went from neck to bra length. She told me it has a lot of water in it. She said to drink water and no soda. I was surprised because it was a coincidence that I’m reading it now and she already… Read more »

This industry is full of ultra-refined, artificially-scented and colored supplements full of unknown chemical fillers, packaged in toxic plastic containers in unknown factories for months on end. There is NO OVERSIGHT OR ACCOUNTABILITY that what supplement companies put on the label is actually what you’re taking because the FDA NO LONGER REGULATES the supplement industry (thanks Orrin Hatch!). Recent busts of REGULATED prescription drugs found that underground companies were buying subscriptions from sick patients, using lethal chemical solvents to peel the labels off of pill bottles, storing the pills in moldy, vermin-infested abandoned houses in various slums, re-labeling the bottles… Read more »
mercla

hair grows approx 1/2 inch per month naturally . Looking at the comparison photos for this product it looks like the growth matches this. So it could be natural growth and not the product itself. I’m not sold on it.

Angel

Just take biotin.

Just take biotin or msm…..save your money !

The pills worked for me but I did cut my hair because I got a trim. I just started back taking them , one hairfinity & one biotin instead of 2 hairfinity pills.

I took hairfinity when I started my hair journey. I transitioned I didn’t BC. My hair was really broken and unhealthy. I had a really bad salon brand relaxer. My friend had mentioned just using some hair and nail pills she didn’t suggest this brand I found it on my own and I used it all the way through my transition(It took like 14 months for my transition). It didn’t grow my hair super long, but then again I was cutting and growing and cutting and growing, BUT it did make my hair strong and healthy . Which is what… Read more »

I personally prefer The Mane Choice vitamins. Very educated woman is the creator and natural ingredients. If you check her IG it’s a ton of real testimonials. I’ve been taking them for a few months and love them. I’m not a promoter or anything just informing young ladies like me of something I personally use that doesn’t get as much media hype yet as hairfinity does.

Tree

I’ve stopped taking these pills because I noticed my front hairlines breaking off,I’m not sure if it was the pills or my headbands,should I still take them?

Raya

It could be the headband, fabric may be rubbing against your hair too much. You should continue to take them and drink plenty of water. Eat more iron and vitamin C foods for blood circulation also.

Darlyn

After the Youtube reviews that I’ve watched, those pills seem like a scam.

Raya

They are not a scam, ppl post on YouTube and don’t include what hair regimen they have done also which may be a factor. JBCO sheds hair like crazy and causes alot of thinning out because of it’s high ash content. But these pills really do work

Adeola @ TheManeCaptain

no, I never believe scientific studies conducted by the company, neither do I trust products recommended by “doctors” and other so called experts or celebrities. I personally don’t recommend taking drugs for the sole purpose of length or other aesthetic reasons. our hair will grow regardless.

JenniD
Do the studies done by product companies themselves hold a lot of weight for you in terms of your decision to buy? I’d say it certainly does make me pick up the product and examine it further but to actually buy it based on studies alone I’d say no. On the whole I believe the whole supplement industry is bogus. Especially when it comes to pure vanity pills like these. Taking way pass the recommended daily does of vitamins and minerals to grow long hair is so not worth the health risk to me. Scientist can’t really agree on wither… Read more »
J.Nicole

It’s so unfortunate to see celebrities endorsing these pills. It seems to be marketed mostly to women in the natural hair community. I know of three women who tried them and the results were the same. They saw some substantial growth, but when they stopped taking the pills, they experienced shedding & hair loss and find themselves starting from scratch. I don’t think it’s wort it.

Tabatha

Well when I stopped taking it I didn’t have that issue. Thank God.I think its worth a try, but you can achieve the same thing if you take a women’s multivitamin and buy a bottle of Biotin at your local pharmacy too.

Tamara

The vitamins work, but it thins out your hair in the process while your hair is growing longer. Its not worth buying Hairfinity. I would rather my hair be long and thick, than long and thin. Its plenty of bad reviews on youtube about it.

Raya

It doesn’t thin out your hair, if anything your shedding dead hair and new growth is coming in stronger and thicker.

DeAnna Anderson

Thats not true. It may have thinned your hair out but it may not happen to everyone that uses it. I use it and after the first month my hair had gotten even more thicker than it already was. My sister used it as well. She wasn’t drinking enough water and when she started taking the pills & the increase in biotin caused her a few dizzy spells so she increased her water intake and she was fine. It made her hair thicker too.

Tabatha
It did that to my hair too. And I NEEDED IT! Its like any other product its not going to be the same for everyone. There are so many natural products that I have seen on these forums and I have tried and it didn’t do a thing for my hair. But I try other stuff and it did great! Like Shea moisture, Kinky kurly, Miss Jessies, and Black and lovely I think it is; my hair hates it, but a lot of naturals rave about it. Just cause it did or did not work for this person doesn’t mean… Read more »
Anon87

So many sing Hairfinity’s praises that I don’t think people care about the company’s scientific study.

My issue is trying to filter out the people who are paid to endorse Hairfinity (celebs are popular natural hair bloggers) and the “normal” people who have had genuine results. It seems too good to be true that simply popping those pills has such amazing results – the world does not work that easy! Lol.

Tabatha

I don’t pay attention to Celebrities. I’m like whatever you have a stylist I need someone who has taken it and does their own hair.

Raya

They actually do work!

Uli

My friend is also using the pills and she is not a sponsor and she also said that they work,she has been using them for a month,said it grew her hair like crazy.

Caramelcurls
The studies done by product companies themselves DO NOT hold a lot of weight for me in terms of my decision to buy. Why? Because the study is more than likely going to be biased to promote marketing the product, there may be information withheld, and the study may not accurately mirror the real world. I’ve personally never take Hairfinity vitamins, so I don’t know whether they work or not. But I’d be more inclined to pay attention to the review of someone that has tried them rather than take the word of a scientific study done by the Hairfinity… Read more »
sandy

Excellent points made. The problem, however, is if you go on YouTube, for example, the vast majority of folks reviewing the product are also sponsored by Hairfinity. Therefore, the issue of conflict of interests still arises. It is hard to get a true sense as to whether it works or not. I, for one, prefer to spend the money on buying nutritious foods that fuel my body.

Tabatha
Before I took it, I watched A LOT of YT videos of people that took it. Some of them just talked about it and others had pictures and documented their journey which was nice. I also looked up every ingredient on the internet. Nothing harmful other than the biotin because if you don’t stay hydrated you’ll get dizzy, you’ll break out, and it could dry your hair out more because you need a lot of water with biotin. I always tell people get a 2 month supply because it takes about 2 months for your body to get acclimated to… Read more »
