A key aspect of hair loss with age is the aging of the hair follicle.  Ordinarily, hair follicle renewal is maintained by the stem cells associated with each follicle. Aging of the hair follicle appears to be primed by a sustained cellular response to the DNA damage that accumulates in renewing stem cells during aging.  This damage response involves the proteolysis of type XVII collagen by neutrophil elastase in response to the DNA damage in the hair follicle stem cells. Proteolysis of collagen leads to elimination of the damaged cells and then to terminal hair follicle miniaturization.
“Proving that bald is beautiful, focus on a healthy shaving and scalp regime,” says Eide. After removing a steamy towel from your head, apply a shaving oil, such as The Art of Shaving Pre-Shave Oil ($25, ), to soften the hair. Next, apply a shave gel if there are moles to watch out for, like NIVEA MEN Sensitive Shaving Gel with Skin Guard ($, ). Otherwise, choose a rich shaving cream—try Neutrogena Men Sensitive Skin Shave Cream ($, )—over the top of the oil. Shave with the grain first. Repeat the scalp preparation, starting with a steamy towel before applying product and shave against the grain on the second pass. Finish with a cold, wet towel and an aftershave lotion, like Dove Men+Care Post Shave Balm ($, ). Looking to indulge? “There is nothing better than visiting your favorite barber for this luxury service,” says Eide.
