There are lotions and prescribed pills in the market which can slow down hair loss and regenerate mild to moderate growth.

But there are side effects such as itchy scalp, temporary hair growth on the forehead and temporary impotence.

A more drastic procedure is hair transplant. This involves removing healthy follicles from the back or sides of the head and grafting them to balding spots.

The surgery takes four to five hours and follow-up checks are needed to wash and monitor the wound.

Transplants should be done only by a trained dermatologist or plastic surgeon.

The effect is permanent and the cost starts from $7,000

A non-invasive solution is hair-weaving, in which human hair is attached to existing hair.

The procedure can cost a few thousand dollars.
