IM A GUY AND NEED HELP!

I straighten my hair to spike it I use a "no-lye" formula I tend to use relaxers well same thing just sold with different name just remember that it best to wait till your hair is about the length that you are going to spike it cuz as your hair grows it will throw off how strait your hair is unless you touch it up I think its to hard for guys with short hair so I don't I can usually go at lease 2-3 weeks spiking it really ez cuz the hair is real stiff but it also gets thinner if you try to relax (straighten) it again on relaxed hair it could fry it and you hair will stretch and break when wet I can't think of anything else
