K18<\/p>\n
Leave-In Molecular Hair Mask<\/h3>\n<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n Why we love it:<\/strong> K18 Leave-In Molecular Hair Mask isn\u2019t your run-of-the-mill hair mask. It still promises similar benefits to that of rinse-off masks (shinier, bouncier, and stronger hair), but it\u2019s a leave-in treatment that’s meant to be applied on shampooed, unconditioned hair\u2014and it’s formulated totally differently, too. Unlike hair masks that sit outside each strand, this one actually penetrates the cortex to repair bonds that are broken during heat styling and color treatments.<\/p>\n“Even though it\u2019s lightweight, it delivers a serious hit of moisture and repair by reconnecting polypeptide chains to strengthen the hair,\u201d says Nast. \u201cMy clients love it, especially those with color or heat-styling damage. Plus, it\u2019s lightweight enough for fine hair so that it won\u2019t weigh you down.” The brand recommends working it through your strands and letting it sit for four minutes to activate (you can layer on your usual styling products during the wait), then styling as usual. Results build over time, so don\u2019t be surprised if it takes a few washes before you start to see what all the hype is about.<\/p>\n

\u201cI put my hair through so much\u2014the blow-drying, the flat-ironing, the re-curling!\u2014my split ends were practically visible from outer space. It wasn’t until I diligently started using this now-classic leave-in mask that I believed you could actually undo years of damage. There’s a learning curve to using it; you need to essentially emulsify the product in your hands, then apply and wait a few minutes, and then continue to style. You also can’t use conditioner before applying. Sure, it’s a bit finicky, but this stuff works\u2014seemingly instantly. I got heaps of compliments after using it for a consistent month; people thought my hair was shinier when blown out, and my curls were brought back to life; their pattern restored, their joie de vivre revived!\u201d \u2014Shanna Shipin, senior commerce director<\/strong><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n

Why we love it:<\/strong> Why should your skin get all the glassy glory? Oribe Mirror Rinse is an in-shower treatment designed to give hair that same high-shine, light-catching finish. Used after shampooing, it smooths the cuticle and boosts reflectivity in just a minute, leaving strands noticeably glossier and silkier. \u201cThis is the in-shower treatment that\u2019s my personal go-to for giving my natural hair the prettiest gloss\u2014and even makes my extensions look extra fresh,\u201d says Kelley Alvarez, a hairstylist based in Oak Brook, Illinois. The shine comes from a smart blend of smoothing conditioners and lightweight silicones, while glycerin helps keep hair soft and supple. Oribe\u2019s proprietary complex\u2014watermelon, lychee, and edelweiss flower\u2014adds weightless nourishment and helps shield strands from shine-depleting environmental stressors. \u201cIt\u2019s super quick to use, and the scent is amazing,\u201d adds Alvarez.<\/p>\n\n

\u201cI\u2019m a huge Oribe fan\u2014the scent alone gets me every time\u2014but beyond that, I always see and<\/em> feel a real difference in how my hair looks and behaves after I use their products. Mirror Rinse is unlike any in-shower treatment I\u2019ve tried before. The texture is completely clear and serum-like. First squeeze out excess water and then apply it directly to your hair (trying to use your hands is a lost cause\u2014it\u2019ll slide right through your fingers), let it sink in for a minute or two, then rinse, using it in place of conditioner as directed. I was skeptical at first that something so lightweight could actually cling to wet hair\u2014or deliver the same moisture as a traditional conditioner. But, as I started blow-drying when I got out of the shower, the softness was immediate. The after photo here has zero<\/em> other product in it besides Mirror Rinse, and my hair (which I only cut twice a year so it’s prone to dry ends) has never looked shinier or felt smoother.\u201d \u2014Christa Joanna Lee, Allure<\/em> contributing commerce writer<\/strong><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n

K\u00e9rastase Nutritive 8H Magic Night Serum fits right in by treating hair while you rest. Instead of rinsing out a mask or dealing with oily residue in the morning, you smooth this lightweight serum onto dry or damp lengths before bed and let it do its thing while you sleep. \u201cIt works like hand lotion for the hair,\u201d says Annie Miller, a hairstylist based in Franklin, Tennessee. \u201cIt smells incredible, and it absorbs completely by morning without any greasiness.\u201d Plant-based soy and wheat proteins and vitamin B-rich niacinamide help nourish and lock in moisture, while iris root extract and panthenol soften and detangle. By morning, hair feels hydrated, smoother, and easier to manage.<\/p>\n\n

\u201cI don\u2019t really damage my hair in the traditional sense\u2014but I do wash it every single day, which can leave it dry and frizzy, especially in the winter. I\u2019ve been using this to wake up to shinier, smoother hair in the morning, and have noticed a difference in the flyaways and breakage (especially around my hairline).\u201d \u2014Deanna Pai, Allure<\/em> contributing commerce editor<\/strong><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n

<\/span>Shanna Shipin<\/span><\/div>\n<\/figure>\n<\/div>\n<\/div>\nWhy we love it:<\/strong> After heat styling or everyday wear and tear, Crown Affair\u2019s new Overnight Repair Serum is exactly what the stylist ordered to repair dry, limp strands. Inspired by the body\u2019s natural overnight cell replenishing and repairing process, it nourishes while you sleep, strengthening, smoothing, and boosting shine, with no rinsing required come morning. I know what you’re thinking, but don\u2019t worry\u2014it leaves behind zero greasiness, making it great for finer hair textures. The source of its silky-ifying powers? A seriously stacked ingredient list, including flaxseed and chia that support repair, while a Tsubaki Meadow\u2019s blend\u2014meadowfoam seed oil and tsubaki, the oil extracted from the camellia seeds\u2014locks in moisture, and rosemary adds a natural shine.<\/p>\n\n

\u201cI put my hair through the wringer\u2014curly one day, blown out the next\u2014so this serum is a lifesaver. It’s weightless, leaves no residue on your fingers, and dries down quickly. No staining your pillowcase or getting a hair mask on your cheeks. It’s meant to be an overnight serum, but I love using it in the daytime, too, essentially whenever I’m brushing my hair smooth\u2014it seals up my split ends so well! On top of all the benefits I see from using this serum, it also has the signature Crown Affair scent; it\u2019s a revelation for damaged ends.\u201d \u2014Shanna Shipin, Allure<\/em> senior commerce director<\/strong><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n
