Scientists in Japan develop a new technique to reverse balding by transplanting a special kind of hair follicle cell into a patient's scalp
Medical researchers in Japan have developed a new technique to help reverse balding by transplanting a patient's own hair cells directly into their scalp to stimulate new growth.
The technique was developed by a team of dermatologists from the Tokyo Medical University Hospital, led by Ryoji Tsuboi.
The team tested the technique on 50 men and 15 women between the ages of 33 and 64.
The result of our study was very encouraging,' Tsuboi told the Asahi Shimbun. 'We were able to show that the study could help develop a new treatment for hair loss.
The test took place over the course of a year, and also involved a group of subjects who were given placebo injections for comparison.The team took small samples of dermal sheath cup cells from hair follicles on the back of a subject's head.The cells were treated and grown to greater quantities in a laboratory, and then injected into the top of the scalp.The team regularly examined the test subjects every few months and found new hair growth seemed to be most active between the six and nine-month mark.
After nine months, the rate of hair growth at the transplant sites slowed again.The treatment seemed to be more effective with older subjects and slightly less effective with younger ones.They also found that increasing the amount of cells transplanted into the scalp did not seem to cause any further hair growth than smaller doses did.According to the team this could have been caused by a variety of factors, including 'cell debris' from the samples that could have prevented all of the extra dermal sheath cup cells from being activated.There could also have been an immune system response that prevented more of the cells from having an effect past a certain threshold.
