15 Top-Rated Hair-Growth Products at Sephora For Fuller, Stronger Hair

The Ordinary Multi-Peptide Serum For Hair Density ($18) packs three different peptide complexes to improve thickness and fullness. Beyond adding density, this product also helps increase blood flow in the scalp so hair grows in healthier.

One key way to encourage growth is making sure your existing hair is in the best possible shape and going from there. This Rossano Ferretti Parma Prodigio Regenerating Treatment ($98) helps repair damage with richly hydrating butters and supports thicker, healthier hair coming in moving forward.

Ouai Hair Supplement For Thinning Hair ($28) packs biotin, amino acids, and sulfur-based MSM, which all work together to increase hair growth. Oh, and there's also ashwagandha inside to reduce the stress hormone cortisol in the body (as high levels of cortisone can damage follicles that help hair grow).

Not only does the top-rated Alterna Haircare Caviar Anti-Aging Clinical Densifying Shampoo ($34) cleanse, it helps block DHT which often leads to hair loss. This shampoo also features a red clover complex to thicken, and adds in ingredients to slow natural, chemical, and environmental aging, too.

This Alterna Haircare Caviar Anti-Aging Clinical Densifying Styling Mousse ($38) also features the brand's red clover growth complex (to stimulate the growth of healthier, denser hair in the future), but its nonsticky polymers can make styles look instantly fuller with just a few scrunches.

The travel-size goodies inside this Briogeo Blossom & Bloom Hair Thickening + Volumizing Travel Kit ($25) help thin hair in the short term, thanks to follicle-stimulating ginger and ginseng that support blood flow to the scalp. There's also strengthening biotin right inside to promote growth at the same time.

The lightweight Better Not Younger Superpower Fortifying Hair & Scalp Serum ($47) has centella asiatica inside to strengthen hair follicles and caffeine for extra support. Those ingredients — along with other vitamins — leave your whole head healthier so hair can grow in thicker and fuller. This product has a 91 percent recommendation rating from Sephora shoppers.

This top-rated Reverie Cake Restorative Scalp Tonic ($72) uses active ingredients like Swiss apple stem cells to delay the aging of hair follicles and promote hair growth. There's also a blend of eight essential oils to ensure hair is smooth on the outside while restructuring is going on inside.

Sephora Collection x Olly: Lustrous Hair ($7) gummies taste like grapefruit and are packed with biotin, keratin, and vitamins C and E for stronger, fuller hair.

Castor oil, beloved for promoting hair growth, is the main ingredient in Seed Phytonutrients Hair and Body Castor Oil ($28). The product helps condition and hydrate, and packs antioxidant-rich argan oil with vitamin E to increase circulation in the scalp so hair can grow in stronger.

Give your scalp a reset with the top-rated Better Not Younger Scalp Detox & Hair Volumizing Kit ($44), which includes a full-size charcoal cleanser and a volumizing shampoo and conditioner duo. The three products work together to remove dead skin cells and buildup at the roots before adding in hair-strengthening ingredients like moisturizing bamboo and antioxidant-rich, conditioning hops.

With a 4.7-star rating and 92 percent of Sephora purchasers willing to vouch for it, this Briogeo B. Well Vegan Omegas + Biotin Supplements For Hair Thinning ($38) is a popular choice to strengthen hair. It's loaded with vitamins along with a vegan omega-3 complex (from microalgae), plus there's biotin to make the shaft and follicle stronger so less hair breaks off.

The niacinamide and biotin in the top-rated Better Not Younger Lift Me Up Hair Thickener ($34) support hair follicle function to rebuild keratin for thicker, healthier hair. The spray gel also coats hair with ceramide NG to protect the shaft and lock in moisture so hair looks instantly sleeker.

The top-rated Kérastase Initialiste Advanced Scalp & Hair Serum ($40) features peptide SP94, which penetrates roots to help reinforce hair fibers. There are also ceramides inside to strengthen against breakage.

These Hum Nutrition Hair Sweet Hair ($10-$25) vegan gummies have biotin and folic acid to help with hair growth, but they also add in tonic herb fo-ti, which is used in traditional Chinese medicine to help scalps stay healthy.
