+1 w/ the previous poster. I wouldn't worry too much about any health problems, or even thinning hair. I've noticed that when styling my hair post shower, there are 1-2 places on my head where the hair looks thin, or I can see a bit of scalp poking through. It's b/c of where the curls have decided to clump, pulling hair away from the scalp. I find that once dry, all I need to do is some upside down fluffing at the roots & everything appears to fall into place w/o any visible scalp issues.
