A Scientific Analysis of Hairfinity Vitamins; Do They Really Work?

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?

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

    • 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 at your local Walmart (cheapest price) Walgreens or Target. Keep me posted :)

  6. 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 the only way to know true results is if someone was living, eating, exercising, and caring for their hair the EXACT same way on Hairfinity as they were before trying the pills. As living a healthier lifestyle in general (i.e. Drinking more water & eating healthier) could definitely be the main component to the healthier, longer, & stronger hair.

    • 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 was fuller, I had less natural shedding and all my itchy scalp issues were gone.

      Hairfinity doesn’t make your hair grow in my opinion… It helps retain length. My hair care regime has always been the same before and after.

      I literally didn’t change, add, or subtract from anything I was doing before, during, or after hairfinity. It works. I think that if you are deficient in some vitamins you see results faster (or all together) because the supplement is providing your body with vitamins you were lacking. If you’re already taking the vitamins that’s in the ingredients then your body would just expel the extra which could be why some ppl don’t see “dramatic” results.

  7. 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

  8. 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 not the length. I was not taking supplements previously and I didn’t change my diet or exercise routines. My growth was legit so hairfinity does work. However it’s the price I’m concerned about, I have come across enough hair pills with the exact same ingredients with around the same amount that cost a good £/$20 less.

  9. 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.

  10. Well I have just orders mine and I will post how I get on I have baught 2 months worth because I never do anything in halves lol so I’ll give u all a real feed bk because I’m skeptical my self x

  11. 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 suggested. HOWEVER, my hair did grow. It was such a shame because I wanted to continue taking it, but it didn’t mesh well with my system. I would tell anyone to try it and see how it works for them.

  12. 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.

  13. 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.

  14. 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 seriously need to hire a consultant. If somebody tips the FDA or even the FCC they will reap them apart.

  15. 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.
