I am 20 this year. Whenever i go to the salon, they always say that i have thick hair. However, until like last year, they start telling me that my hair is very thin.

It is like a little window opening at the back of my head. i can still cover it up by combing my hair with different partings. My parents told me that it might be because my hair has been in that parting for years.

However, now i have realized that my hair has been dropping. I don't used to see my hair falling whenever i dry them. now after drying my hair, there will be about 3-4 strands falling. i m not paranoid, but i hope that i can find out if it is abnormal and what can i do about it?
