The scalp is normally an oasis- all of the follicles in the galea and the sides are getting adequate watering (hormones and circulation). You will find that every follicle is having good natural flow from the body. This is for both men and women.
One of the first things that you will need to do to regrow lost hair or reverse male pattern balding, is to reverse the restriction and constriction of the bloodflow. The band surrounding the galea or the sides of the temporalis, is what is closing the top off from growth.
The side effects of this causes the fibrosis/calcification of the dermal papilia, arteries, and the blood vessels. This is the direct cause of hair loss. This is the direct cause of the hair not restoring back after DHT is eliminated. The restriction is key to setting back the clock on hair growth.
