The best split-end serums can make damaged hair look dramatically healthier, smoother, and shinier temporarily, though they won’t replace a fresh haircut (that’s the only true fix for frayed ends). “Once the strand has split and separated at the end, there's absolutely nothing that will bring it back together permanently,” says New Jersey-based stylist Michelle Cleveland .
Even though they may not be able to repair existing breakage and brittleness, split-end serums can still help “prevent more damage and further splitting of the hair,” says Los Angeles-based hairstylist Ashley Ruiz . “They help seal and coat the hair from UV heat and thermal styling.” So whether your frayed ends are the result of frequent heat styling, color appointments, rough brushing, or everyday wear and tear, these formulas are designed to smooth rough cuticles, soften brittle strands, and help minimize future breakage.
Some split-end serums rely on lightweight silicones to temporarily seal and smooth frayed ends, while others are powered by nourishing oils that replenish lost moisture and boost shine. Stylists also recommend bond-building treatments to help strengthen weakened hair from within, as well as styling creams that double as heat protectants to defend against one of the biggest causes of split ends in the first place. Think of split-end serums as equal parts quick fix and preventative treatment: They won’t permanently repair a split end, but they can disguise existing damage while helping keep future fraying at bay. If your strands are rough, prone to breakage, or in need of some extra smoothing, these are the split-end serums truly worthy of a spot in your routine.

Allure commerce editor Sarah Han applying the Mise En Scene Perfect Serum
Why we love it: Talk about a product that lives up to its name—Mise en Scène’s Perfect Serum is powered by Moroccan argan oil to hydrate and nourish dry, damaged strands and leave them silky, smooth, and dare we say almost perfect. What’s more: A blend of six more oils (including olive, coconut, and apricot) helps detangle, soften roughness, and minimize split ends. It doubles as a heat protectant up to 446 degrees Fahrenheit, so apply it after your shower to prep hair before styling. The light, fresh floral scent is a bonus, although it is also available in a rose-scented formula for those who want a more palpable aroma.
P.S. Other variations include the Watery Serum for thinner, easily weighed-down hair, and a Super Rich Serum for thicker, drier hair. There's something for everyone, which is why Mise en Scene's our top pick!
