10 Best Hair Masks for Hair Growth, Tested and Reviewed 2025

“I like to apply three to four pumps of this mask to my hair. Not only does it keep my ends soft and prevent them from drying out, I’ve also noticed about an inch of growth since my last haircut while using this. Not only that, but my ends look extremely shiny and healthy in my after pic, about a month-and-a-half later,” says Glamour contributor Ariel Wodarcyk.

Best Hair-Growth Mask for Thick and Coarse Hair: Vegamour HYDR-8 Deep Moisture Repair Mask

This silicone- and sulfate-free hair mask was love at first wash for me. It has a heavenly white floral scent and an extremely thick consistency that reduced my amount of hair shedding as I blow-dried. Plus, its benefits extend past washday. “[The mask] is powered by Karmatin, a vegan keratin alternative, which coats the hair to make it instantly appear thicker and doesn’t wash away with rinsing,” explains Dr. Nathan. It’s packed with marula and moringa seed oils, which smooths frizz and prevents breakage.

The Vegamour mask was also a favorite for our coarse, curly-haired reviewer. “My thick, curly hair felt more pliable and easy to style after just one use,” they said. In two months, their hair grew a little over two inches. They can vouch for the claim that the mask’s benefits last several days too—each time they wet their hair in the morning, they found it easier than usual to restyle.

Best Hair-Growth Mask for Scalp Health: Jupiter Purifying Mask

According to Matt L. Leavitt, DO, FAOCD, a board-certified dermatologist in Florida, scalp health is key when it comes to hair growth, and this mask helps with just that. “If the scalp is not cared for properly, build-up from sweat and excess oils can block hair follicles, resulting in a range of issues, from inflammation to severe itching,” he says. “Jupiter’s Purifying Mask supports exfoliating the scalp to clear away dry skin and rid the scalp of any product buildup.” The mask also contains biotin, which “works to fortify the hair shaft and encourage healthy growth,” says Dr. Queen.

Wodarcyk swears by this and the Kérastase Resistance Masque Extentioniste duo. “This mask has a foaming, mousse-like texture. You can apply it to wet or dry hair, then shampoo and condition as usual. I used this formula once a week on my roots and my hair grew almost four inches. The first time I tried it, I applied the mask to dry, fourth-day hair, the longest my hair can go without a wash. I left it on for several minutes before shampooing and was delighted by the cooling, mild tingling sensation I felt on my scalp. It was easy to wash out, and it left my hair feeling cleaner than just a standard wash. Plus, it helped keep oil at bay for the following days—by the time day four rolled around, my roots had only a slight sheen and my scalp felt balanced. In addition to cutting down on oil, it left the hair at my crown looking and feeling fuller.”

Best Hair-Growth Mask for Hair Shedding: Kérastase Genesis Masque Reconstituant Hair Mask

“The Kérastase Genesis Strengthening Hair Mask gave my thirsty, curly hair some much-needed TLC,” says one reviewer with fine, 3B curly hair. “I let the mask sit on my wet hair for longer than the directed five minutes because I know my weakened hair could use the extra time. After I rinsed the mask out, my hair instantly felt more moisturized and was easy to detangle. I was surprised at how soft my hair felt once it was fully dry and how my usually dull hair had an extra shine after only one use. My only ‘complaint’ was the highly fragranced scent, but thankfully it didn’t dry out my hair like some parfums do.” She added that although she liked the mask, she had still expected to see more visible growth. After one month, her hair grew slightly less than an inch—still more than the average rate of hair growth.

Inside the formula, you’ll find Edelweiss native cells and gingerroot, “which deeply feed and strengthen the hair, making it more resilient and encouraging smoother, healthier strands,” says Aanand Geria, MD, FAAD, a board-certified dermatologist and founder of Geria Dermatology in New Jersey.

Best Smoothing Hair-Growth Mask: Marc Anthony Grow Long Restoring Anti-Breakage Mask

This under-$10 mask is formulated to smooth the hair’s cuticle and enhance elasticity, thanks to a combination of hydrolyzed keratin and growth-promoting ingredients like caffeine and biotin. The texture is pleasantly thick, so a little went a long way on my hair type. In fact, after almost one month of use, it still looks like I’ve barely used up any of the product.

My hair felt soft, shiny, and had a noticeable reduction in frizz after each use, though I did notice it weighed down my volume if I applied too much. In terms of hair growth, I noticed a little over half an inch in less than one month—not bad considering the extremely low price point. If you live in a humid climate where you’re constantly battling frizz and are interested in growing your hair out, this is an excellent budget-friendly pick.

Best Leave-In Hair-Growth Mask: K18 Leave-In Molecular Repair Hair Mask

This viral leave-in K-18 hair mask is beloved by hairstylists, influencers, and derms alike. It promises to repair hair and fight damage on hair’s molecular level in just four minutes, thanks to its patented K18 peptide technology. “It works by reconnecting broken keratin chains; restoring strength, elasticity, and smoothness to damaged hair without weighing it down,” says Dr. Geria.

The K18 peptide mimics the structure of actual hair, Dr. Geria notes, which helps strengthen strands that have suffered the consequences of bleach, color, and chemical treatments. Unlike some of the other masks on this list, this is a leave-in treatment; you can apply it to shampooed, towel-dried hair, then style your hair as usual.

“The mask quickly absorbs into your hair with minimal residue and is very lightweight—moreso than a traditional conditioner or leave-in—making it a great option for finer hair like mine,” says Glamour contributor Bella Cacciatore. “I’ve been using K18 for a few weeks now—every wash for four washes at first, as recommended by the brand, then about once a week—and the difference is pretty noticeable. My hair feels soft and smooth, and looks bouncier and healthier, especially when I blow it out. I’ve also noticed my slight waves are more defined, and my broken baby hairs near my crown are less likely to stick up straight since incorporating K18 into my routine. Basically, it’s shampoo-commercial hair in a bottle—it’s worth the price tag and the hype.”

Best Hydrating Hair-Growth Mask: Briogeo Don’t Despair, Repair! Deep Conditioning Mask

This mask expertly quenches dry, damaged hair while promoting strands’ strength and elasticity, thanks to its high-impact ingredient list. “Moisturizing ingredients like rosehip, almond, and avocado oil hydrate and improve hair elasticity, biotin strengthens the hair shaft making hair stronger and more resilient, and algae extract is an anti-inflammatory and antioxidant,” says Dr. Queen. In addition to hydrating hair and fighting dryness, this mask is fantastic for smoothing frizzy hair and making it more manageable.

“The before image here is from February of this year. I had just stepped out of the hair salon and dyed my hair back to dark brown after years of highlighting it. The highlights underneath did end up coming through after two months which is why my hair is now a brown (which I love!). After this hair transformation, I started incorporating the Briogeo hair mask. It’s now April and my hair feels so healthy. I’m able to blow dry it and style it without feeling like I’m drying out my ends. I’ve noticed less hair breakage and frizz. The mask has been a great addition to my haircare routine,” says Glamour senior commerce editor Jenifer Calle.
