Good and consistantly available
This product has stopped my hairloss. After my last child was born, 25 years ago, my hair has been slowly thining. Throughout that time I have tried many products. One I really liked was discontinued. Others were a waste of money. This mix of biotin, collagen and keratin, works well. It’s consistantly available.

Great product compared to other similar products.
This seemed to really be working! I have tried other similar supplements for months and really did not see much improvement, but my nails are already much stronger and my hair is definitely growing faster. I think my skin is even looking better. I’ve only used the product for five weeks, but I plan to continue..

Wow!!
If youre looking for something to look and feel better, this is it! I have tried even the most expensive of supplements and this did things in 2 weeks that others couldn’t accomplish in months.My skiiiinnn… omgosh. I looked down at my hands today and they weren’t dry, wrinkly or anything. They look hydrated and smooth! My face looks that way too!! Very encouraging for what happens later down the road.My hair is really thin normally and I can tell its thickening up! It looks so healthy and shiny too.My nails are growing at a rate they’ve never grown before.BUY it. I just ordered another bottle cuz I dont want to miss a sngle day.

Great for growing/adding density to head and body hair
I got this for my girlfriend as she wanted this to grow out and make certain areas more dense. She took it and it seemed to work. Smells okay, the size is swallowable, doesn’t taste too bad either. Quality seems good and its a standard brown pill color. So of course, easy to use.

LONG Natural Nails and Long Hair
I’ve always has long natural nails and long hair. I ordered these a couple weeks back to help more with my nails, because I’d been neglecting them (which is not like me but life happens). I’m taking them twice a day, first with a multivitamin and a vitamin C, and then in the after noon also (I’m taking them after a small meal, or snack and not on an empty stomach). I can see a difference already, with my nails and hair. These vitamins are simple and easy to take with no after taste as all. I need to add, we have animals… miniature goats, rare cats and two dogs. I’m always having my hands in and out of water, and tending animals. I think these vitamins are REALLY helping my nails be stronger and NOT peel and break!! (Will see how my hair grows in coming weeks!)

Results and value for money
I’ve used it in the past have always been satisfied. My hair doesn’t break and it grows fast. My skin looks better and feel good as well. My nails not so much.

Amazing results from the start!
I bought this for hair and nail growth, but immediately noticed a couple of things. I was taking the same amount of biotin before, yet stopped mine and took just this ( same mg). I noticed right away my rapid nail growth. Second, I had severe frozen shoulder and only advil alleviated that massive pain. But after a week, the pain lessened that I now don’t have to take advil. I haven’t noticed any hair difference, yet it hasn’t even been a month and I am so thankful for this vitamin!
