Dr. Vlad Ratushny, a regular columnist in the the prestigious hair transplant publication Hair Transplant Forum International, was recently featured discussing new findings in the field of hair growth biology. In this article, Dr. Ratushny describes how olfactory receptors (typically used to transmit our sense of smell) have been discovered by scientists in human skin. The researchers in the study, published in Nature Communications, showed not only that smell receptors are found in the skin, but that specific odorants (e.g. a synthetic variant of sandalwood) could potentially stimulate hair growth. Further studies will be necessary to determine whether these findings can be translated into new therapies to promote hair growth.
