New findings from a study on hair regrowth may bring us closer to a cure for baldness. We take a closer look at the research to find out how.
Growing hair on damaged skin
Researchers from the NYU School of Medicine in New York recently published a paper detailing their investigations into regrowing hair on damaged skin. As you may have noticed on your own body after an injury or surgery, areas of scar tissue are generally hairless. Until now, scientists believed that this lack of hair growth could be due to collagen build up. However, this new study suggests that fibroblast cells and the curiously named Sonic the Hedgehog pathway also have an important role in hair regrowth.
A new remedy for baldness?
The NYU researchers already knew that the Sonic pathway is involved in sending communications between cells and activating fibroblast activity. In humans, this pathway is very active during foetal development but becomes less active as we age. They compared two groups of mice to see what effect stimulating the pathway would have on wounded skin. Their findings showed that after one month, hair growth was evident in only the mice that received treatment. The scientists who worked on the study hope that they will be able to reproduce the same results in human skin, with the overall goal of helping to develop new hair loss medicines.
Many people feel self-conscious about having scars on their scalp from an injury, surgery or skin condition. The lack of hair growth makes scalp scarring more noticeable and may attract unwanted and embarrassing questions. Although it is not currently possible to regrow hair on scar tissue, there is an innovative solution that can help to disguise it. Vinci Hair Clinic’s Micro Scalp Pigmentation is a non-surgical technique which has some similarities to a tattoo. The treatment can be used to effectively camouflage scars by applying pigment to reduce the contrast between the skin and hair colour. The result looks completely natural and is ideal for those who want to take control and feel confident about their appearance again.
