After I decided to take a mirror to look at the back of my head, I saw that my situation was such that over the counter remedies would not be helpful. So I googled and happened to find the only Trichologist in my State, Delaware, so that's how I went to her.
After reviewing the questionaire she had me fill out, She examined my head and took pictures. After I told her about the keratin, she knew exactly what I needed. She said that most keratin damage occurs due to the heat of the flat iron. She also shared that the heat of most flat irons on the market DO NOT test out to be what they are advertised. If someone's hair is thin, previously treated with keratin, or colored, they may require less heat than what's normally called for in the directions. She said my hair loss occured when the excessive heat w/the keratin treatment disintergrated my hair's cuticle (yes, that is the word she used).
