Hello, I am currently in the research process of my science fair topic. I am investigating the effect of chemically lightening hair on hair composition.
I have a few questions that I wanted to ask in order to make my project the best that it can be.
-What is the process that hair goes through when it is chemically lightened?
-Are certain types of hair more susceptible to damage from chemical lightening?
-How does hair react with humidity? (i plan to use a hygrometer to measure change)
-What would have more of an effect on the hair, time dyed for, or dye concentration?
-Would the amount of day to day damage to the hair effect the change in composition after chemically lightening?
Thank you for your time. Any help is greatly appreciated.
