Here, we reveal the best hair growth serums to add to your routine. Whether you’re looking to repair breakage, spot treat a sparse hairline, or just introduce some va-va-voom volume, you’ll be sure to find a formula that meets your hair goals. These serums also keep the hair you already have healthy and thriving, which is crucial when you’re trying to encourage length. For example, many formulas contain antioxidants, which can help combat free radicals from UV rays or pollution. Finally, you’ll find plenty of humectants and fatty-acid-rich oils to moisturize the strands and keep them strong: “The hair on your head is probably the driest thing on the body, and if you are trying to grow it longer, you need to keep it moisturized,” says hairstylist Anthony Dickey regarding faster hair growth. “If your texture is naturally drier, it is even more essential to keep hair hydrated. Dry hair turns to brittle hair, and brittle hair breaks.” While you can always give yourself a tension-relieving scalp massage with nothing but your fingertips, a scalp massager tool can help you address those hard-to-reach places, like the very back of the head or behind the ears. This Brush From Hairstory is a solid option to use in and out of the shower, or find mbg’s full list of favorite scalp massagers here. Check out our list of collagen supplements, or if you’re looking for a one-stop shop, go ahead and grab mbg’s beauty & gut collagen+. In addition to 17.7 grams of grass-fed collagen peptides and 500 micrograms of biotin, it has vitamins C and E for enhanced collagen production and antioxidant support, hyaluronic acid for skin hydration, and curcumin from turmeric extract and sulforaphane from broccoli seed extract for supporting detoxification and combating oxidative stress.* If you think you might be dealing with buildup, try folding a scalp scrub into your routine. With these, you can choose physical exfoliators, with granules (like sugar and salt) to manually remove buildup, or chemical formulas, with naturally exfoliating acids and enzymes to dissolve dead skin and lift up debris. Our high standards also come from testing products—many, many products. Our editors and writers rigorously test and research the products featured in our roundups to offer you the best, most informed recommendations. When we write reviews, you can trust we spend quality time with the formulas: We don’t simply rave about products we’ve slathered on the back of our hand. We endorse products we’ve tried and loved.
