I experienced a drastic hair loss/thinning that was sudden and no cause was diagnosed. I started using the grow new hair treatment and the change has been dramatic! So many people comment on how much thicker my hair has become. pretty much back to normal. . I have never been so impressed with a product line in all by adult life! I will admit it has taken time but I honestly saw a difference after one month. I am so happy I found a natural alternative.
