ThinningTry: Minoxidil “It’s a bit like fertilizer for the hair,” says Paradi Mirmirani, MD, a fellow of the American Academy of Dermatology. “Minoxidil has been well studied, and there’s good evidence that it increases the diameter of each strand, the density of hair, and the rate at which hair grows.” Find it in Pantene Hair Regrowth Treatment for Women ($40, amazon.com), a scent-free serum. Slow growthTry: Anti-dandruff shampoo Even if you don’t have flakes, research suggests that the pyrithione zinc in anti-dandruff shampoo may promote hair growth, especially if you’re dealing with buildup or scalp scaling, Dr. Mirmirani says. Try Aveeno Nourish + Dandruff Control Shampoo ($12, amazon.com), which soothes and nourishes the scalp with oat extract. WeakeningTry: Natural oils “Oils improve hair’s tensile strength,” Dr. Mirmirani says. Bonus: “They help smooth the cuticle, which can be lifted by wear and tear.” Support weak strands with coconut oil–containing Garnier Fructis Damage Eraser Strength Reconstructing Butter ($13, amazon.com).
