Injections of ‘platelet-rich plasma’ (PRP) which have been extracted from the blood, are already used to combat ageing on the face and hands, reported the Sunday Telegraph.
In the latest research by scientists at the International Hair Research Foundation, the University of Brescia in Italy and the Hebrew University Medical Centre in Israel, used 45 sufferers with alopecia areata, affecting two per cent of the population.

Cancer patients’ gray hair unexpectedly turned youthfully dark while taking novel drugs, and it has doctors scratching their heads.
Chemotherapy is notorious for making hair fall out, but the 14 patients involved were all being treated with new immunotherapy drugs that work differently and have different side effects. A Spanish study suggests that may include restoring hair pigment, at least in patients with lung cancer.
With the first patient, “we thought it could be an isolated case,” said Dr. Noelia Rivera, a dermatologist at Autonomous University of Barcelona.
UT Southwestern Medical Center researchers have identified the cells that directly give rise to hair as well as the mechanism that causes hair to turn gray – findings that could one day help identify possible treatments for balding and hair graying.
“Although this project was started in an effort to understand how certain kinds of tumors form, we ended up learning why hair turns gray and discovering the identity of the cell that directly gives rise to hair,” said Dr. Lu Le, Associate Professor of Dermatology with the Harold C. Simmons Comprehensive Cancer Center at UT Southwestern. “With this knowledge, we hope in the future to create a topical compound or to safely deliver the necessary gene to hair follicles to correct these cosmetic problems.”
