I started with Evolution hair care Sept 2015 because I was a 35 year old woman with thinking hair at my crown and I was very concerned. I had lots of hair shedding. The folks at Evolution hair are very understanding and informative. I started with the vitamins, shampoo and laser and started seeing results within 6 weeks! My hair stylist even noticed all my new growth! You have to follow their instructions and you will see results! Thank You Evolution!
