At first, I was a little skeptical since I was having sudden hair loss with no known medical reason. I saw this product and was impressed with the nutritional information. I am glad I decided to try because within two weeks my hair was starting to 'stop' shedding, I could feel the thickness return gradually. The softness and sheerness and shine is returning as well. The only thing I struggle with is the flavor. Normally I can tolerate just about anything but this one is difficult, however, it is worth making the horrible face I make for the improvement in my hair. I am not skeptical any longer.

I love the original product. It really does help with the skin nails and hair, but what is up with this new vegan formula?!! The smell is almost unbearable! I am not vegan but I feel bad for anyone who takes this and is Vegan or vegetarian because it smells like processed meat!! It is really a shame because if it’s anything like the original it’s a great supplement, the original just had a better smell...

I bought these vitamins and have been taking them religiously for 2 months now. I wanted thicker, stronger hair, longer and stronger nails, smoother hydrated skin and joint health. It’s too bad the other reviewer threw them out because of the smell of the vitamins. Yes, the vitamins do have a funky smell but let me tell you that my hair is longer, thicker, and much stronger (lot less fallout). My nails are much stronger and are growing like weeds. My skin is brighter, hydrated and firmer. In addition, my joints are no longer stiff like they used to be. I am going to continue using these vitamins. They are doing wonderful things for me.

Be patient with the product . Our bodies process anything you eat at it’s own pace . Don’t expect a change over night. I will definitely continue to use this product. Very happy and seeing a change .

I am wrapping up the 2nd month on this supplement. I know with any vitamin , patience is key. However, my skin looks great and I can see the new growth in my hair where it was thinning. I am 45 & I just accepted I had thinking curly hair. I am pleased with it & will continue to use.

So, I have been using well-known brand name and obscure, never heard of "hair, skin, and nails" supplements for nigh on ten years now, with no appreciable improvement in my hair, my skin, or my nails. But, because I'm persistent if I'm anything, I decided--based on reviews--to try yet one more supplement. And, because I know that it sometimes takes more than 30 days for a product to show results, I bought the three bottle package. I am only on my second bottle and HOLY COW! Once again, my refusal to give in or give up and live with the status quo has paid off. The bald spot I've been trying to solve is completely covered with hair. The skin on my hands, which was already pretty nice, seems younger (and at my age, I'll take any improvement I can get). My nails, which have been prone to splitting and breaking and have been plagued by lots of vertical ridges are completely smooth. One of my 10 nails still feels a bit weak, but there has otherwise been a significant, visible improvement in my nails. This product is staying on my subscription list and I'm cancelling my standing orders for all other similar products. This product--Skin Research Institute Renewglow Biotin Supplement--really works as promised. Imagine that--a product that does what it promises. Gotta love it!
