For all you girls (if any) with neck length hair, how do you guys keep your hair protected I have to wear collared shirts for work and I work almost everyday. My hair snags on my collar sometimes. Am I doing any damage to my hair? it's growing and I don't see any damage but I'm just asking to make sure. I have a couple more questions...1)Does anyone know if silk elements lye regular will get my hair 85-90% straight? Or does anyone know any lye relaxer that I can get from sally's that will do that? I'm tired of my hair coming out underprocessed and poofy. Lol. & 2) How long does a tube of lye relaxer last. And how do I store it? Lol. Thanks guys.
