Why do people go bald?
Our hair grows from hair follicles. We have about 100,000 hairs on our head. Everyday, we usually lose about 100 hairs. If new hairs don’t start growing from those places, then we are probably balding. Medical term for baldness is alopecia.

One of the main reasons for balding is hormones.  We have have a hormone called testosterone. In our body, testosterone is converted into Dihydro testosterone or DHT.

Now, some people’s hair follicles are highly sensitive to dihydro testosterone. Hence, their hair follicles begin to shrink and their hairs gets thinner and thinner. Eventually, the hairs fall off and no new hairs grow on those places, leading to baldness.
