I'm 19 years old and my father(55) still has hair on his head. I started losing my hair when I was 17.5 years old. For almost 6-8 months I have this white pigment on my scalp which just won't go. It's mainly near crown and that's where I'm mostly losing my hair from. I've tried oiling and anti-dandruff shampoos but it's still there. It makes my head very itchy and when a hair breaks off, there's this white hard thing at end of it. I consulted a doctor and he thinks it's just dandruff.
