While there’s no accessory quite like it, maintaining healthy hair can be fickle and frustrating. If it’s thick, it may not be reaching your desired length fast enough. If it’s fine, it may have begun prematurely thinning. If you’re stressed, it could be falling out more than usual. The same goes for if hair loss runs in your family, you have a scalp infection or are undergoing medical treatment. Hell, you might even be experiencing hormone changes and noticing your hair growth at a sudden standstill.

Long story short, hair loss or slowed hair growth is a condition many women will confront in their lifetimes, but that doesn’t make it any less intimidating. RxSaver dermatologist and Byrdie Beauty & Wellness Review Board member Dr. Dendy Engelman specifies diet can be key when it comes to retention or accelerating growth (she recommends eating clean proteins as well as vitamins A, B, C, and D), but proper hair care can be the secret weapon to promote—or restimulate—hair growth and prevent hair thinning before it starts.

“Don't overprocess the strands with lots of chemicals, that will stress your scalp,” she says, “You want to make sure that you are using mild shampoos and regular washing to keep the scalp clean. If you are concerned about future thinning hair, you can pick products now to ensure your hair is as strong, healthy, and dense as possible.” So whether you’re seeking to clear the scalp of sebum to stimulate hair follicles, improve the overall strength of each strand to reach Rapunzel length, or all the above, you're in luck.
