Around the world, scientists and doctors work tirelessly to advance hair restoration techniques. In this blog, we summarise some of the latest developments.
New Pathways to Hair Restoration
A study led by Angela Christiano, Ph.D.at Columbia University Vagelos College of Physicians and Surgeons found a new signalling pathway in stem cells. The researchers discovered that the JAK-STAT pathway maintains dormancy in the hair follicles of mice. When a JAK-inhibitor was used, the team were able to switch on the follicles so that they produced hair again.
Improved cell-sequencing technology allowed the team to find another factor involved in the JAK-STAT pathway. They discovered a previously unknown type of cell related to the immune system. Named trichophages, these cells produce a substance called Oncostatin M. The team were able to block the production of Oncostatin M by using molecular inhibitors and antibodies.
These new findings present a new approach to treating hair loss and, according to Christiano, could help in the development of topical medications.
3D Printing to Solve Hair Loss?
Another study by the team focused on growing hair follicles using stem cells. In the past, scientists have had difficulty growing human hair follicles, partly because it was hard to imitate the natural conditions of the skin. Now, the latest 3D printing technology can be used to make specialised structures for the hair to grow in. Hair follicle cells, keratin-producing cells and growth factors placed in these structures resulted in hair follicle development after three weeks.
The ability to grow hair in laboratories is an important step towards treating hair loss. It would allow scientists to perform large scale tests on medicinal treatments, and could potentially provide an unlimited supply of hair for hair transplant surgeries.
Treating Hair Loss Today
With new hair restoration treatments still in the early stages of development, what can hair loss sufferers do in the meantime? Vinci Hair Clinic, leaders and pioneers in hair loss treatment, offer a selection of state of the art solutions. These range from FDA-approved medications and medical treatments like PRP, to surgical hair transplants. They also offer the innovative non-surgical Micro Scalp Pigmentation procedure, which simulates the appearance of hair growth through the skilled application of pigments to the scalp.
