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

London
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 ?

Roszenia
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.

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

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.

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

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.

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.

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

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.

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).

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
