I have a thinning scalp. I don't see visible hair loss, such as loss of hair when I shower or comb, but the scalp is thinning. There are large gaps between hairs. On the other side I have quite a long hair, longer than 30 cm. I can see through my scalp when I see the mirror and I feel like I have very less hair on the left side of my head. When I comb my hair I can see I have lost a lot of hair on my left temple compared to the right. Can someone kindly tell me what kind of problem I am going through and the possible solution for that.
