Why Am I Shedding???

I don't normally shed as much as I have been lately. Every time I run my fingers through my hair, I lose a couple strands. I think it's the result of a bad relaxer I got from my best friend's mom. Why? She combed the relaxer through my hair! It's a BIG NO NO because the chemical is already straightening the hair and combing will only overstretch the hair. Plus, she didn't leave the neutralizing shampoo on long enough. I'm just going to have to shampoo my hair (with a neutralizing shampoo), condition, deep condition, and air dry. After, I'll probably do some cornrows.
