I Had long thick hair and I used Wen back in 2011.My hair started to break off and thinned out.
I went to my dermatologist not realizing it was the Wen product. He gave me blood test and said I was just ageing. I started using my regular Nioxin recommended by my dermatologist. After a year my hair got thicker longer.
I then went back to Wen because I had some left over and my hair started breaking off and thinning all over again!
So now I went back to the Nioxin and my hair is healthy strong and much thicker again.I am considered to be mixed race with African American trace.
