Much like Cher, they work so well, they're a singular sensation. In that elite echelon resides Olaplex, of course, and Joico's K-Pak, a protein and keratin treatment that all but reverses the time-speed continuum to restore your hair's health. And for today only, its sister product, Joico's Defy Damage Protective Masque, is on sale for a primo 30 percent off. Where the K-Pak line is focused on deeply penetrating to rebuild brittle hair bonds after color changes, the masque — and Defy Damage line in general — is targeted to protect strands from heat styling. To really get the ingredients into your hair, the brand relies on a "SmartRelease Technology" that uses liposomes to deeply deliver rosehip oil, arginine, and keratin; vitamin E, moringa seed oil, oat peptides, and coconut oil also feature front and center. A good lineup, and if the name "arginine" rings a bell, it's because the strengthening ingredient is also at play in this lash-strengthening serum from one of Meghan Markle's favorite brands. Joico describes arginine as a "smart-bonding molecule with both positive and negative sites, [which] helps to strengthen hair bonds and encourage bond renewal;" shopper-favorite hair growth brand Viviscal also incorporates the ingredient for its anti-aging effects when taken internally, and one study found that arginine protects hair proteins and hair surface lipids. Courtesy Shop now: $17 (Originally $24), amazon.com That superstar and its compatriots make for a potent five-minute treatment, according to reviewers. Of the people who've left thousands of five-star ratings, the phrases "saved my hair," "great for hair repair," and "magical" proliferate, which gives you some idea of their passion for the creamy formula. "I've always liked Joico products, but this product takes the cake. The scent is heavenly, and your hair will feel like an angel's after you use it," continues one of the shoppers above. "SO soft and shiny, and it doesn't weigh your hair down (for my fellow humans with fine or thin hair). A little also goes a LONG way. I promise you won't need more than a dime-nickel size amount." Others say the Masque took their hair from "frizzy and damaged" to smooth and soft, and split ends from daily styling recede in lieu of "beautiful shine." One person says it's helped their hair grow faster, and another writes: "My hair has started growing and has a shine. It's still thin, but doesn't look brittle and damaged. I love the results." To that end, someone else details how a tip-off from their stylist saved their scalp from a sparse fate. "My hairdresser recommended this product, and I'm glad she did," they wrote. "I think it's [the] one thing that's helped prevent me from going bald." More than a few reviewers' hairstylists directed users towards the "amazing" product — and you know it's good, because even those just looking at Masque's effects comment on its impressive results. "My hair has been so dry since bleaching it," says one person of the experience. "This has been a lifesaver. This is my go-to saving grace for damaged hair — it's like I never bleached [it]." A last person who colors and heat styles their hair comes in with the greatest compliment of all: "This is the best deep conditioner! Way better than Olaplex. This is probably my fourth tube. I use it weekly, and my hair looks and feels so healthy." The masque is 30 percent off today only as part of Amazon's Holiday Look event, so if any of those outcomes sound up your alley, jump on the $17 deal before the Masque's price reverts back to $24.
