I use the Eu Natural Biotin 5000 mcg (search for it on Amazon) and it has been working great. Much healthier and fuller hair, and my nails have also become stronger. I take it every day with lunch and a full glass of water. Right now, I'm growing about an inch to my hair length every month.

There are quite a few different brands out there so it may take going through a few to find the one that works for you. They aren't all created equally! Some aren't potent enough, others can make you break out, and a lot of them are made in China.

NC25 Chinese, acne prone.

I bought a bottle Nature's Bounty from Costco after seeing a blogger rave about it for stronger nails (mine were bendy and starting to peel without understanding why at the time). Took the bottle home, read the MUA reviews and saw the potential acne trigger but figured you never know til you try so only did low dosage of 1 pill per day....

Used it for about 3 weeks, and cystic city! Took a few weeks to clear up. So yes it's true, can trigger acne. No bueno for me.

I've been using Biotin for about 4 months now, starting on 2,500 mcg and now I'm on 10,000 after gradually working my way up. My nails are super strong and my hair is growing faster than usual and in better condition (not so thin and less split ends). I did experience some acne at the start but not anymore, however I have been using Sweet Almond oil and that was what cleared my skin up. I have now advanced onto Paula's choice and that is sorting out blackheads :) If you want to see results you need to up the dosage and be prepared to wait about 2-3 months to see results as that is about how long it takes for most supplements to starting working in the body.

I buy my biotin online at as it is way cheaper than trying to find it in New Zealand, you can use my discount code for $10 off a $40 purchase... DWQ834

18th March 2013 i bought biotin after reading reviews on here. i have naturally curly hair that usual grows no longer than underarm level.
i trimmed my hair in july and its hardly grown back i bought biotin!! (10,000mcg)

ANYWAY ive been taking it for about a month now and there is noticable growth, my hair is back to its usual length (under arm length) so im hoping it will continue to grow.
i do get acne from taking it, but i found that if i take if with meals, the acne is not as bad.

i havent noticed that my hair has become thicker but definately longer!

ill keep on posting and let you know if theres any progress...but so far all good news and worth buying..i would 100% recommend.

3rd april 13 havent noticed any other changes since i first reviewed this product hopefully there will be more results in 3 weeks.

So I am on my second bottle of biotin(100 capsules per bottle) MY HAIR HAS GROWN 3/4 inches which is a lot of growth for my hair type my hair is thicker and I feel like damage from previously dying my hair has been repaired. No more acne breakouts linked to the biotin and my nails grow super quick. 23rdjuly13

I originally started taking these because I heard great things about this vitamin stimulating hair growth so, I went out and bought a bottle of 1000 mg at Target. I've been taking these for about two weeks. The first week I only took one and everything seemed fine however, by the second week of still only taking one 1000 mg tablet, I noticed my skin erupting in tiny whiteheads and a large pimple on my forehead and four on my chin. I am acne prone but I usually only get one or two before or after my menstrual cycle. Since biotin had been the only change I had made I decided to do some research and I found out that this may indeed be the cause of this whitehead eruption I am experiencing. I know it is said to drink a lot of water when taking this vitamin, but I normally drink 2 liters of water daily and I still got breakouts. I strongly do not recommend anyone who is acne prone to take this vitamin. I'd rather have my hair grow at its normality, which will require me to be extra patient, than have to deal with acne. Who's with me? I'm definitely throwing these out in the trash.

I've been using 10,000mcg of biotin daily for about 4 months now, in conjuction with a prenatal for healthy hair and nails. I've noticed that both are in much better shape, and have luckily not had the facial acne many others discussed.

I bought a Rite Aid brand Biotin 1000 mcg for my hair and nails mainly. My nails tear and my hair falls out in my brush and in the shower, and pretty much all over my house. I started taking these pills a little over 4 weeks ago. The first couple days, I had cystic acne on my cheek, but just 1. I didn't think anything of it, and it went away in a couple days. I haven't had any breakouts since. I take only one a day with food and lots of water, and I have started to notice a difference in my hair, nails, and skin. My nails aren't pealing at all, and my hair isn't falling out as much. I know this sounds weird, but the skin on my elbows is totally soft.

I work at a skin care company, so I get facials a lot. My face is already soft and mostly clear, but I have even noticed a difference in my skin. It doesn't break out anymore right before my period, and I use less makeup, if use any cover up at all.

I haven't noticed that my hair or nails are growing any faster, but they are definitely growing stronger. I am thinking about taking 2 pills a day to see if I notice a difference.

If you have acne prone skin take biotin at your own risk! After just two days of taking biotin I could feel all of these hard lumps forming on my face and they were very very painful. A week later they had turned into full on boils. The worst was one right between my eyes that I had to have lanced by a dermatologist. It took two full months to get my face back under control. I still had massive scarring but the boils eventually went away. Mind you, I was literally drinking 9+ bottles of water while taking the biotin and it still didn't help. Beware of this stuff if you have reactive skin. I would hate for anyone else to go through with I did just to get longer hair or nails!

Upon the suggestion of my doctor, I purchased some Nature's Blend Biotin, 2500 mcgs. I had read the skin care board so I was prepared to NOT overdue the dosage and to drink LOTS of water. Also, because I have hypothyroidism (the reason for my hair/nail issues), and because I had a Non-Elective, full hysterectomy a couple years ago (as soon as my ovaries were removed my life-long cycstic acne cleared up in mere days) I thought I would escape the hormonal acne that had happened to others who took Biotin. I eat a plant-strong, very clean diet. I took 1 tablet with breakfast, drank a ton of water all day and worked out/performed skin care as usual. I thought, those poor other people had problems, but I won't.

WRONG!!! The third morning I woke up with 2 painful, large cycsts emerging on either side of my chin. I'd forgotten how much those suckers hurt! I thought that maybe they'd actual stop growing and go away if I perservered. NOPE!! I skipped a day, the cysts continued on, so I continued taking it for 3 weeks. More cysts emerged, and now I had painful (and weird) pimples/cysts appearing around the base of my nose and around my mouth, and then backne appeared. (I've never had backne!) I called my doctor and said I was unwilling to go through the cystic acne issues, and asked if the hair/nail results would be worth it. I was told that I shouldn't be having the acne issues because I had no ovaries. I offerred to drive in and show the gross, painful cycts to her in person. She declined.

I have ordered Swanson's 1000 mcg & 300 mcg Biotin, and will give it a very limited try (AFTER my face clears up from this round). I'm praying it will work, as I have limited options for help with my hair & nails. However, I'm not willing to battle cystic acne all over again. Sorry to have posted TMI, but, I thought it may help other women who have had total hysterectomies to know that even w/o their ovaries (and w/o estrogen replacement) they can still get cycstic acne from Biotin (if they are sensitive to it, which apparently I must be). I put "yes" I would buy it again ONLY because I am hoping that the 300 mcg tables will be tolerable--and if they are, then I will continue to use it. I gave it a 3 rating because it didn't get used long enough to help me, and I didn't want to pan it w/o trying a lower dosage first. YMMV.

UPDATE: New cysts stopped popping out on my face 2 days after I stopped the 2500 mcg of biotin. They have been very slow to heal, and are still red & are leaving marks. I took 1 week off, then tried the 1000 mcg tablets for a week; as soon as I updated this review a new round of breakout/cysts started. I've still seen no change/increase in hair/nail growth, except that my sparce eyebrows have grown thicker (hmmm... not exactly what I'd hoped for, LOL). I have stopped using Biotin and won't be using it again. I wish it had worked for me. : (

Newest Update: A glutton for punishment, I tried the 300mcg biotin tablets. Call me desperate; call me older and wishing for thicker hair and "normal" nails.... well, after 2 weeks, just call me cystic-face. OUCH! And that's after a nice long break from the last round with 1000 mcg. Even 300 mcg won't work for me. :( I tossed them all. Am sooo disappointed.

I was initially interested in biotin, because my hair has been shedding for years. The initial brand I bought at the local health food store was 1000mcg per pill. I'd read about acne stemming from usage, so I was ready going into it. Literally over night I woke up to 3-4 little whiteheads. I rarely get pimples. Just to test, I took two more pills that day and the next day there were more. I stopped using them, and decided to order a different brand from iHerb dot com. They arrived last week, 5000mcg pills. I haven't had a pimple with this new brand. I'm not prone to acne anyway, but I wonder if even different brands have different temperaments?! I haven't been using it long enough to notice results on hair or nails, but as far as acne goes it might just take some shopping around?! I'll come back in a few months to discuss results of my long term biotion use...
