My goals were stronger nails (mine peel and break a lot) and faster hair growth. I was on biotin for a total of 6 months.
I started off on a very low dose of this, taking three tablets a day for 3 months. I didn't notice any difference at all, apart from a horrible acne break out that lasted about a week (when I first started taking them). I endured the acne, got over it and continued with the biotin. Still nothing. I then started taking a much higher dose of biotin and had to put up with another breakout from the increased dose, which I think it was 7.5mg. I took these ones for about another 3 months. Still nothing worth writing home about. I didn't see any difference in my hair growth at all. There was a *slight* difference in my nails. Less peeling and they were stronger but I don't think it was worth it. Honestly, I don't see why I even bothered. Nothing amazing happened at all but I'm happy that it works for some people. I've been on a very healthy diet since October (I was very unhealthy during my biotin taking months) and I'm going to see if my new diet does anything for my hair, skin and nails. Good luck everyone :).

I have gone through 1 bottle (100 tablets) of Biotin 1000mcg. I have not noticed a change in hair growth or nail strength. I also did not break out. I had been taking 2 tablets a day.

So I bought biotin when I had heard some mediocre reviews and decided to try it for myself. I am African-American and I have coarse hair that takes a long time to grow. While my hair were in braids, I decided to take it (which was about 2-3 months) because I was not using heat, or washing constantly, or any other damaging thing to my hair. My hair definitely grew about 2-3 inches (I don't know exactly), but I really am pleased with it. If you're black and you're taking it, try going about 2 months without relaxing your hair, and keep in braids with extensions or without (I used extensions). I just had regular single braids, and put oil to my scalp about once a week and did a deep conditioning oil treatment once every two weeks before I went to bed. The actual texture of my hair did not change and neither did my quality (softness, thickness, etc.). The only bad thing that I did notice about biotin is that my skin was more oily, especially around my nose. I just used a DIY nose peel and that helped.

All in all, the growth was great, but it wasn't like 10 inches in a week, so as long as you use it every day, and take care of the scalp, it should work pretty well for you. I hope this was helpful!

I took 1000mcg for two months. I'm really disappointed because nothing happened. I have long straight thick hair, and my aim is waist length, - it didn't grow faster. I have average (not particular weak but not exactly strong either) nails, and they didn't change either. I think I'll try a skin, hair and nails supplement next time.

Biotin (5000 mcg Spring Valley from Walmart about $6 - I've tried others online but I like this brand) gives me about an inch of hair growth per month. (I'm currently on my third month.) I noticed it taking effect after I took it for six weeks. I take 3 of these - 15,000 mcg per day (converts to 15 mg) but i think 10 mg is probably sufficient enough. I take these every night before bedtime and strangely, being on that routine helps me fall asleep quicker. My nails are obviously longer and my hair has grown MUCH quicker which was my goal. I'm pleased with my inch every month. I haven't noticed my body hair growing longer or thicker than average, maybe somewhat quicker but it hasn't been significant enough to bother me. No hairgrowth in unusual places. No facial hair. Clear skin. No bad side effects whatsoever. I would recommend this to anyone. :)

UPDATE(01/22/14): Hello all, it has been a while since I last updated my review on Biotin. I have religiously been taking it since I started about 2 1/2 years ago. My nails grow rock solid and so fast, I constantly have to cut them down. My hair is ok I haven't reached my goal length yet but I am sure it is because my ends are so beyond dead and I refuse to cut it lol. I continue to take Spring Valley Biotin but now I take the 10,000mcg tablets with 100mg of Keratin. My skin is better than EVERRRR and I know it is the Biotin because if for whatever reason I happen to miss a day or two BOOM my skin doesn't feel the same. It is great, try it and I hope it works just as good for everyone else! :)


UPDATE: I have now been taking Biotin (Spring Valley Brand 5,000mcg) for 3months now and it has drastically improved the condition of my nails. Within the first month they were rock solid and longer than ever. I keep them short now since they grow so quickly. My hair has definitely within the last month or so. At first I did not think my hair would grow, but at least it got my nails growing but now I am convinced it is helping my hair, I am only several inches away from my hair reaching my waist. I am so excited for it to keep growing! (: and as for my skin, no breakouts its actually better than ever. I will update once my hair has reached my waist. The condition of my hair also feels better. Good luck to the rest of you ladies!


Hello Ladies,

I have been reading several reviews on here about Biotin. I just purchased a bottle of 5,000mcg yesterday, so today will be day 2 of my Biotin intake.. A little about me now: I have pretty nice hair, its straight, average thickness, it is about half way down my back which is not short but I feel like it has been stuck at this length forever now! I am desperate for it to grow, I have for the majority of my life had hair down to my waist and miss that length. I do use the blow dryer and flat iron, not as much anymore but hopefully Biotin will help. I also would love for my nails to grow, they get a little long and then they get caught on something and I am back at square one. The only thing I am scared of is the possibility of breaking out, I have a little break out every month when my period comes but nothing extreme so hopefully this won't affect me in that department. I will update in about 2wks and share my experience. Thanks for reading!

This vitamin is incredible!!! I don't know why it doesn't work on some people, but on me this works within days. Granted I don't buy the generic brands at pharmacies and buy them online instead, where you have larger concentrations, the cost is cheaper, and the pills are smaller. My favorites are the Biotin (5,000mcg) from Vitacost. Wonderful stuff.

Anyway, I have relaxed hair. For those who don't know, this is hair that is chemically straightened. Not temporarily, but completely and permanently removing the curl. Now, I don't have a problem growing my hair but I've been wanting to grow out the relaxer. Since I don't have time, money, or patience to sit down and get braids regularly or do protective style, growing it out "naturally" has become a problem. Ever since I started taking this I've been able to cut my relaxed hair gradually since the curly parts are growing faster and longer. Since taking this, my hair has grown 4 inches in 3 months. And the curls are SOFTER. I'm not making that up, I have mostly thick 4a hair that shrinks and tangles too easily, and since taking them my hair growth is softer are more defined. My nails, which are naturally very fine, have grown stronger and clearer. My eyelashes have grown quite a bit too, and they are darker (less mascara baby!).

On the downside, this has made the hair in other places grow much faster. The hair on my legs grows thicker and faster, the hair on my arms (which is also very fine) is growing longer. The hair on my brows grows a bit faster as well and longer. I was freaking out a bit about this because I swore they were thinning out thanks to constant waxing at my brow lady. The hair on my lips grows just a bit quicker. But that is nothing consistent maintenance can't fix. I use an epilator for my legs and that inhibits my growth for about 3 weeks to a month. I use Gigi Hair Removal Lotion on my arms and Surgi facial cream for my lip area. It's tougher to maintain my eyebrows but I don't mind.

I recommend taking this with food once a day, don't try doing so twice if it's 5,000mcg or more. You'll be asking for a breakout. I also suggest you get a hair vitamin on the side. I use Maxi Hair as a multi-vitamin and it works great. Most of all, if it doesn't work as fast as it did for me, don't give up, try drinking more water. This is the biggest reason why Biotin doesn't work on many people. You need lots and lots of water to help Biotin dissolve. My mom tried this and at first it didn't, because she didn't like drinking water too often, and after she started to, wow. I recommended it to another young friend of my brother's that's in high school and trying to go natural. She finally did the big chop after 6 months of taking it and her hair is so cute. Her hair is past her eyes. Don't be stubborn and give it a try, and also try to keep an effort in maintaining your self healthy. Like all other things, it needs a little help on your side to work. Good luck people, and if you have any questions, feel free to message me anytime, I'll gladly respond.

i wanted this to work for me so badly. about a month ago my hair started falling out in larger than normal clumps. my doctor told me it was a condition called TE, which of course has to do with the one thing i cant control.. stress. there isn't much i could do, but figured i'd give biotin a shot. i've been taking about 2000-3000 mcgs a day for the past couple weeks, and unfortunately i havent noticed a difference. not in my hair or my nails. i do seem to be breaking out a little more than normal, but i cant attribute it to this for sure. perhaps it can't help me because of the TE, but i at least expected for it to make my hair a little more shiny or my nails a little stronger. since there doesnt seem to be any cons about it, i will finish the bottle. maybe i havent been taking it long enough, or taking enough at time. if anything changes, ill be back to edit.

This stuff works simple! I take 5000mg a day and it makes my hair grow much faster than usual, almost 50% more.

The only downfall is the break outs, drinking loads of water use an anti bac face wash and you should be fine.

I will never stop taking biotin.

I have mixed feelings about this product. I bought it for my hair after an atrociously short haircut... no offense to people with short hair, but it just looks horrid on me! I picked this up at Whole Foods... and of course, I chose the Whole Foods brand as it was the cheapest there. The capsules are vegetarian, which is a bonus for me.
Anyway, results. I have NOT seen MIRACULOUS results. I've seen good results, however. My hair didn't grow six inches in a month, it probably grew the same amount as it always does. I have noticed that my hair is somewhat stronger, however. Which means less split ends. I have noticed the best results in my nails, they use to be brittle and just plain crappy but now they can grow fairly long without breaking off or chipping.
My skin did have somewhat of a negative reaction to the pill at first, but that was expected. I had a few cystic acne spots for the first two weeks... nothing I can't handle after going through my teen years. It hasn't made my skin amazing though, it's basically the same as always.
I should probably mention that I'm using a very small dose so that my body doesn't freak out too much, especially since I doooo have acne-prone skin that will just flare up if I change anything in my diet too drastically. I think most people take 1000 mcg or 5000 mcg, I actually take ONE 500 mcg pill a day. It's not very much, but I figure I can just up the dosage steadily if I feel the need to after this bottle runs out.
