What is the best thing to do with thin flat hair? I inherited this type of hair and used to use gel, blow dry it, and then use a curling iron, but felt like all this was causing heat damage. I am now letting all the layers grow out, and am just using Pantene shampoo and conditioner, and blow drying on a low heat setting with no gel or hair spray. My hair looks thin and flat, but it does feel healthy. Any suggestions on how to get my hair to look thicker? Thanks!
