New research may lead to a topical medication could delay male pattern balding, also called androgenetic alopecia. The research was conducted by L’Oreal in Paris, and it looked closely at hair follicles and stem cells that cause hair to grow. They hope to one day develop a cream or shampoo that staves off the male pattern balding by encouraging hair to “wake up” from its domancy phase.
The hair growth cycle has three phases: anagen, catagen and telogen. The anagen phase is when the follicle creates a hair, and the hair grows for several years. The hair follicle begins to shrink in the catagen phase, and the hair falls out. The follicle becomes dormant in the telogen phase for several months. Then the cycle starts over.
In male pattern balding, however, the follicles in areas sensitive to hormones get smaller and smaller, producing thinner, smaller hair. Eventually, the follicle stops producing a hair and remains in the telogen phase forever.
