It helped me when I was loosing hair due to unknown reasons. But It made my body hair thicker too LOL

I was taking the 1000mcg & I've heard you should be taking 5000. Well just the 1000mcg broke me out with under the surface acne that hurts to touch, within the next day. Literally. I'm sad because i was excited to have long thick nails & same for my hair. Anyone should try it & see if it works for them. I got a bottle for $3 at walmart. continued >>

I started using after I read it would promote hair growth. And boy oh boy did it work and still working. In the past 4 weeks my hair has grown at least an inch. I am amazed because I have very fine thin limp hair that I've used foil hilights for many years. I put a lot of effort into keeping it as healthy so it's not friend but it just would grow. My hair was sitting on my shoulders now it's a good inch blow.

The downfall, it did break me out bad for the first few weeks. But since than my face has cleared. Im thinking my body just had to adjust to the dose. I take 5000 mgs a day, 3 at night and 2 in the morning.

I took Nature's Bounty Biotion vitamin and it made my nails grow stronger & faster and my hair some as well. I liked it until I noticed my skin started getting clogged and bad acne bumps on my face, chest, and head. I didnt even know it was Biotin until I read info online and I read on the ingredients list of mine that it contained silica. Not good for my skin and I cant stand bad skin! I'll likely never take Biotin again unless its a very small amount in a multi-vitamin. I dont recommend if you sensitive skin, allergies, or not great immune system. continued >>

I started using biotin 90 days ago, I know because I took the last pill frOm a bottle of 90. Anywho, I have thinning hair and this did not help in any way. In fact my beautiful, strong nails became paper thin. I was willing to deal with the nails if it helped my hair! I wouldn't bother.

Biotin did great things for my hair, I used it for two weeks, and almost immediately I could see the difference in my hair. It looks healthier and thicker. After two weeks of taking one capsule daily, I started having really bad acne. My skin was really clear before I started using this product, so I am discontinuing my use of it. It's a great product if you don't end up with huge pimples all over your face.

i've heard that most people's bodies already produce more than enough biotin each day, but for me there is no doubt that a supplement works well.

1st off, a lot of ppl say that it breaks them out. let me address this by saying that the human body is a very sensitive thing-- a lot of times a slight change in diet can make a person break out untill their body adjusts. this seems to be the case with Biotin. my skin is VERY acne-prone, and when i started taking biotin i found that i did indeed get breakouts, but at the 2 week mark they were going away. so if you take this and breakout, keep taking it and give your body time to adjust, b/c the benefits are awesome!

i take 7,500mcg a day (equal to 7.5mg). i think its important to note that theres no toxicity level-- you can take as much as you want and it wont hurt you any. :) (http://en.wikipedia.org/wiki/Biotin)

as far as results, i've been taking it for almost a year, and have noticed an EXTREME difference in my nails. i used to have slow-growing brittle nails. if i didnt ALWAYS have nail polish on theyd immediately break and take forever to grow back. now i find that i can wear nothing on them at all and they dont break and grow REALLY fast. so fast, in fact, that i have to clip them quite often, which is how i know they grow quicker now. i clip them really short, and a week later they're back to being fairly long.

as far as hair growth goes, hair grows slower than nails by a lot. and my hair has always grown kind of fast, but i do think i see a difference. not in hair thickness (at least, i dont THINK so), but in hair lenngth.the way i look at it, is that hair and nails are made of the same stuff, so if my nails are growin fast, my hair must be too :)

lastly, i think a bottle of 100 or so was $6-ish, so not too bad at all, considering i only take 1 per day.

UPDATE 11/5/11:
so, i took this for a little ver a year, like a year and a few months or so. for a while my skin was ok, but maybe about 6 months ago or so my skin started breaking out worse, despite me making no changes at all. as i know biotin can be very acnegenic for some people, i'm taking a break. i stopped taking it about a week ago, so we'll see how it goes, if my skin improves at all. i started taking silica (horsetail) about a month ago, so i'm hoping that will be enough to keep my nails and hair growing. i took off 2 lippies b/c i think it IS the biotin that's making my skin crazy :( and in the end, even after a year of not missing a SINGLE day's supplement, i'm not so sure it was having much of an impact on my hair. i could for sure see a difference in my nails, but my hair..? MAYBE.

i'll update again after a couple months or so, to say if my skin's any better as a result of no longer taking biotin.

UPDATE 02/20/12:
i havent used this in maybe 3 months now, as i switched to silica/ horsetail. out of nowwhere i started getting a bunch of cyctic breakouts. i'd been taking this for a LONG time with no problems, but when i stopped, the breakouts went away! the silica gives me stronger nails, although not quite as strong as with the biotin. no skn issues though! :) my theory is that too much of it had built up in my system and my body was just finding a way to get out the excess.

I brought two bottles for $45. It was okay. I brought this for my nails because my hair is already long and healthy but my nails not so much.I think this also made me break out but I'm not so sure. The only side effect was this made me have to go to the restroom at least twent times a day. I swear on all I love. I know that with this product the excess is removed from the body through urine so I'm guessing I already had enough in my system that the rest was removed from my body. Overall did not see a difference.

Oh my goodness. This broke me out, I think. I started taking it - only 1000mg/day - and into the second week I got 3 cystic, painful lumps on my chin/jaw area. I do usually get one small one with pms, and it was that time - but one was 3 times the size and really painful!!! Never amounted to much, but left a scar. All three did. I Also got two others at back of my head above my hairline!! Really sore - this *never happens to me*. This is the only thing I changed...I'd like to try taking it again because of it's benefits, but this sucked, and I'm a bit afraid!

So I have been taking biotin for about 4 months now and I've seen some great improvements in my hair and my nails. My hair has grown about 3-4 inches in 3 months, which is a lot for me. Usually it maybe grows 1/2 inch a month. It's not thicker or anything it just grows faster. The downside to this is hair everywhere grows quicker so I have to shave more often. My nails are also very brittle and they have gotten a lot stronger. They break a lot less and don't have as many ridges in them. I've been taking the 1000mcg about 2-3 times a day after a meal. I also have acne prone skin and have never had a problem. I don't think you need high doses of this stuff to see results. I think most of the people who get acne from this are probably taking too much. Your body only absorbs so much of it at a time anyways and the rest is released through your urine. I recommend trying this out for anyone looking to grow their hair faster and make their nails stronger.
