Hair loss is a common problem affecting millions of people worldwide that causes significant psychological distress.1,2 The advent of stem cell-derived topical cosmetics means new treatments have become available. In this case series, a topical hair serum containing PTT-6™ from CellResearch Consumer Health is used.

Derived from mesenchymal stem cells of the umbilical cord lining, which is the richest source of stem cells in the body, PTT-6™ signals cells to regenerate, increase cell turnover and stimulate the natural production of collagen, elastin and hyaluronic acid. Furthermore, PTT-6™ causes prolongation of the anagen phase, thus, restoration of a normal hair follicle cycle, stimulation of hair follicle development and suppression of apoptotic cues. A topical product like this might help patients to reduce hair loss and improve hair quality with an easily accessible over-the-counter product, without the need to see a dermatologist or face the cost of hair transplantation.
