First of all, I'm not a native english speaker so what i'm going to share might be wrong in grammar. Anway, I've noticed this problem since the age of 27. My dad has a thin head of hair by 3 of my older brothers still have full head of hair. I was wondering why this happened to me, back when I was about 28 the crown are started getting thinner so I've decided to shave my head with probably No. 3 and my head looked great. After a while I was thinking to color up my hair so I put those perm chemical things and left it for hours and hours. I wasn't so sure that caused the problem on loosing more hair.
I've started taking propecia and minoxidil and it worked really well. But I'm a kind of person who doesn't want to take any meds into my body so I've stopped taking propecia and still using minoxidil 5% but apply only one time at night due to I don't dare to put it in the morning as I have a buzzed head probably No. 1 so people will see my oily/wet head.
