I've been reading a lot of posts where this is described and I think I might have fine hair but I don't really know. My hair is not really thick and I'm not sure of the type it's a 4 something. I know that my hair gets weighed down with creamy moisturizers so I have to use a spray moisturizer and a little oil. I am relaxed but not bone straight my hair still has a slight wave when wet. So how do you all know you have fine hair? Is it something you just know or do you discover over time? Sorry if this sounds silly and thanks for any replies.
