"If a follicle can be encouraged to produce a thicker hair, often pigment will also ramp up," says Alan J. Bauman, MD, of an unexpected—but welcome—side effect of stimulating hair growth. "Using minoxidil can make more pigment deep in the hair fiber. It's not going to reverse completely gray hair, but hair can get thicker and darker."

When a hair follicle is weakened by age, heredity and other risk factors, the fiber diameter, length and pigmentation can diminish. Using treatments like Formula 82M minoxidil, Laser Therapy or PRP can help improve the follicle function and hair regrowth, producing a thicker, longer, more pigmented hair over time. --Dr. Alan Bauman - Bauman Medical Group - Formula 82M Minoxidil
