TikTok has taught me so many things about hair: How to make a perfect bun, cut my own bangs, and choose colors that don't clash with my skin tone (goodbye icy blonde dreams). It's also taught me about damage — namely, how easily hair breaks and how painfully long it takes to restore to health. When it comes to repairing the breakage, frizz, dryness, and split ends that come with heat and chemical styling, a few products have stood out to shoppers, like the Sunatoria Premium Keratin Hair Mask (Buy It, $15 with coupon, was $28, amazon.com).

As so many fellow #hairtok fans already know, keratin is a naturally occurring protein that makes up the structure of your hair and nails. According to a 2018 study from The International Journal of Cosmetic Sciences, topically applied keratin protein can mechanically improve the strength of damaged hair, making it an effective ingredient in so many bond-building products. In addition to these hard-working proteins, the Premium Keratin Hair Mask also contains vitamin E, which promotes growth by improving scalp health. (BTW: Jennifer Garner said this repair serum changed her hair "more than anything else.")

"This can't ever be discontinued because I cannot live without it," wrote one shopper, adding that this "holy grail" keeps their hair strong, smooth, and tangle-free. Another reviewer noted that their hair went from "dry and brittle" to feeling like they "had a treatment from the salon" after one use. Even one shopper with "badly damaged" and thinning hair wrote that "after using this product routinely, the thickness and length are returning." (Pssst: Rihanna and Selena Gomez use this product for healthy-looking hair.)

To reap the full benefits, reviewers recommend applying the mask to clean, damp hair, and leaving it on from five to 15 minutes before rinsing. To get your hands on real results ASAP, head to Amazon to shop this "miracle in a jar" while it's nearly 50 percent off.
