Each hair develops from a follicle — a narrow pocket in the skin — and goes through three phases of growth. Anagen (A), the active growth phase, lasts two to seven years. Catagen (), the transition phase, lasts about two weeks. During this phase, the hair shaft moves upward toward the skin's surface, and the dermal papilla (the structure that nourishes cells that give rise to hair) begins to separate from the follicle. Telogen (C), the resting phase, lasts around three months and culminates in the shedding of the hair shaft.
Finally, avoid damaging your hair and scalp with harsh products and too much time in the sun. Use sulfate-free shampoos, remember to apply conditioner, and cover up outdoors. If you spend time in the pool, use a clarifying shampoo that removes chlorine from your hair. Also, rinse well with lukewarm or cool water. If you take good care of your scalp and hair, you’ll find that it’s easier to keep your locks thick and healthy.
You can also get a hair-loss kit from Hims, which comes with both minoxidil and finasteride. Keeps has one, as well. And though it might seem like overkill to take two different hair-loss treatments at once, this is one of those rare instances where more is actually better. McAndrews calls the combination of orally administered finasteride and topically applied minoxidil a “full-court press” against hair loss. “That’s doing the most you can for preventative medicine.” Rieder notes that taking both drugs together is more effective than taking either one alone.
