My sister has recently bought a hair diffuser, as only she has curly hair in our family, and I have somewhat wavy hair like my mom. Her hair looks great now, and much more manageable as they were earlier. I wanted to know from some hair expert whether a person like me who has long thick and wavy hair, could also be benefitted from hair diffuser! Moreover, since I normally use leave-in conditioner on my hair, would I be required to use it after using hair diffuser on my hair! Please somebody help me with some important advice! I shall be extremely grateful to you!
