I have naturally curly, puffy, and frizzy hair. I can spend hours straightening it, brushing it, and anything else to get it straight but it always goes back to being a puffy mess. People have commented about my hair looking in-brushed and it's getting annoying. Not only that, but it's hard to take care of, because straightening it is damaging my hair. Any suggestions on how to get my hair straighten, that won't hurt my hair?
