We are now running a full hair transplantation service safely and according to Government guidelines. More details here

The team's pioneering work looked into hair follicle biology – specifically looking at what influences hair growth and the role of epithelial stem cell populations.

The team investigated the biology and pathology of the hair follicle as a microcosmic miniorgan in which many of the fundamental problems of biology can be studied in an exemplary fashion. Research included investigations into the neuroendocrine properties of the human hair follicle, their impact on mitochondrial function and hair follicle immune status, and the use of adult stem cells populations associated with human skin appendages for regenerative medicine purposes.

The Manchester University project, led by Dr Nathan Hawkshaw and colleagues, published their findings in May 2018. The main finding was that a drug originally designed as a treatment for osteoporosis has a dramatic stimulatory effect on human hair follicles donated from patients undergoing hair transplantation surgery.

Currently only two drugs - Minoxidil and Finasteride - are available for treatment of male pattern baldness (androgenetic alopecia). The only other option available to patients is hair transplantation surgery.

The Manchester team sought to develop new ways to promote human hair growth.

They found a drug used to treat brittle bones could help to treat baldness within days by blocking a naturally-occurring protein that prevents growth and induces male baldness.

Experts are "optimistic" the drug, known as WAY-316606, could one day help millions of men.

The study on hair follicles donated by more than 40 balding men under-going treatment with Dr Shahmalak at Crown Clinic. It found their tissue all started sprouting hair within days of being treated with the drug.

It was published in the journal Public Library of Science Biology.

Dr Hawkshaw said: "The fact this new agent, which had never even been considered in a hair loss context, promotes human hair growth is exciting. It could one day make a real difference to people who suffer from hair loss.

"I’m very optimistic it could work. In lab tests, the drug started promoting growth in hair follicles in just two days – that’s pretty quick.

"We are looking at using it as a topical treatment, a gel or shampoo that could reach the follicle."
