Best Amino Acid product, EVER !!

5 people found the following review helpful

Posted by Sickness-ELIMINATOR on Aug 11, 2013

NOW L-Cysteine is an amino acid that is an important component of hair, nails and the keratin of the skin. I took this product with a multi-vitamin for months. I did notice my hair growing faster and thicker!! If this will stop working, I will add Biotin and MSM with it and will let you all know how that works. . . . You can find other products I use on my Page! I use only products that have Scientifically Proven benefits (or taste good).

Before my hair fall out about 30-50 a day. It felt like my hair was under nourished and was thinning noticeably. But after only a couple of days of taking this product, my hair roots started to get stronger and no more than 10 hair a day fall out. I'm really impressed with it. I used to try L-Methionine, L-Tyrosine, and L-Arginine but nothing worked on my hair like L-Cysteine. This is my second purchase, coz I gave my first bottle to my mom who is also seeing RESULTS!!

If you need 'brighter skin' without 'expensive brightning creams', get this one.(I`m korean) It really works.
