Laser Comb Does It Regrow Hair

The laser comb is a new device that is gaining a lot of attention as a way to regrow hair quickly and easily. The theory behind this tool is that the light heats up the scalp and give better blood flow to the hair follicles. Considering that the number one cause of hair loss in men can be attributed to male pattern baldness this heating may make a difference. The jury is still out.
Male pattern baldness is caused by DHT in the blood stream. DHT is a metabolite of testosterone which is the male hormone responsible for the growth of the male sex organs during puberty along with other things. Actually women also have testosterone just in not as large a quatities as the men do. The testosterone can have the same affect on the hair though because women suffer from a condition where hair falls out in patches known as female pattern baldness. The causes are the same as for the men. The excess DHT in the blood stream builds up at the boundary between the hair follicle and the blood vessels. This buildup eventually chokes off the flow of nutrients and oxygen to the hair growth mechanism and the hair dies. This condition takes a while to come to an end which is why you see the hair on a man who is going bald turn whispy and thin before it actually falls out. Eventually though the hair succumbs to the loss of vital nutrients and oxygen and dies.
The laser hair comb is designed to increse the blood flow to the scalp. The feeling is the increased heat will cause more blood flow which will counteract the decreased flow caused by the DHT buildup. Laser hair growth would be caused because the increased blood flow would allow the nutrients and oxygen to get to the roots of the hair. There are two main laser hair restoration tools on the market today. There is a laser hair comb and a laser hair brush. Both of these use low level lighting to supposedly increase the amount of hair growth.
It has been claimed that the FDA has certified the laser hair comb and laser hair brush for use as hair restoration appliances. This is not the case. What the FDA said was these tools would not cause any damage but they specifically did not run scientific tests to see if they actually performed as advertised.
The laser brush seems to have a little larger following at this time but it is hard to tell. I would suggest you visit several manufacturer's websites and see if the information seems good to you.
