"Others are taking hair follicles out of human scalp and growing them with dermal papilla cells," Cotsarelis says. "If they grow in culture, you might be able to recombine them with skin cells and form new follicles. This would let you expand the number of follicles you get for a hair transplant. This may not be that far off -- five to 10 years, maybe. There's very good evidence you will be able to do that."
1. Minoxidil. It’s the only FDA-approved topical nonprescription medication that can claim to regrow hair — and it should be part of any hair-loss plan if you have serious thinning, says Rogers. Minoxidil has loads of research to back it, but it requires commitment. If you quit using it, your hair will start to lose ground again. Use a 5 percent strength, like Women’s Rogaine 5% Minoxidil Foam ($30), once daily to see results in three to four months, says Rogers.
Minoxidil: This medicine is applied to the scalp. It can stop hairs from getting thinner and stimulate hair growth on the top of the scalp. The U.S. Food and Drug Administration (FDA) has approved minoxidil to treat hair loss. It is the only hair re-growth product approved for men and women. A dermatologist may combine minoxidil with another treatment.
According to Men’s Fitness, Minoxidil will help slow the hair loss process, preserve the hair you have, and regrow hair more quickly. The six month supply of unscented topical solution is clinically proven to help regrow hair and revitalize hair follicles. The easy-to-use application can be used once daily. Simply apply the solution along the scalp using the dropper.
That meant new products like Hims and Keeps were out.Hims and Keeps are relatively new companies that allow you to set up a subscription for hair loss treatments. Both offer finasteride (after an online consultation with a doctor) or 5 percent minoxidil. However, their minoxidil solutions contain propylene glycol, so we cut them from consideration.
In either sex, hair loss from androgenetic alopecia occurs because of a genetically determined shortening of anagen, a hair's growing phase, and a lengthening of the time between the shedding of a hair and the start of a new anagen phase. (See "Life cycle of a hair.") That means it takes longer for hair to start growing back after it is shed in the course of the normal growth cycle. The hair follicle itself also changes, shrinking and producing a shorter, thinner hair shaft — a process called "follicular miniaturization." As a result, thicker, pigmented, longer-lived "terminal" hairs are replaced by shorter, thinner, non-pigmented hairs called "vellus."
