I'm a new memeber and i'm not sure what type of curl I have (they all seem to fit in one way or another), but I'm having a serious issue with grease or product build-up (I'm not sure). What happens is that I take a shower- shampoo my scalp, then condition the tips and brush the tangles out- and afterward, when it starts to dry, I notice that the center of the back will be kind of sticky to the touch (the place where older men most commonly get bald spots is the only way i know for sure how to describe where this happens). I'll rinse it again, but it doesnt seem to make a difference. It really bothers me, because it's not only affecting the volume of my curls, but it seems to creep down my scalp a bit and make my hair matted in the back. It also sometimes looks like it isnt curly at the top anymore sometimes because the "stuff" is weighing it down. My hair has been curly for about 5 years now (it changed around the time I hit puberty) and I've never had it do this to me. My only problems in the past have been frizz. I don't use any other products in my hair besides shampoo and conditioner, and that has always worked wnderfully for me......any ideas what I can do to get rid of this mystery "stuff" and get back my otherwise delicious volume?
