Fortunately, some of the best hair-growth products don’t require a treatment with a dermatologist or trichologist – meaning you can achieve thicker, longer hair right at home. With that and the ever-evolving hair-care market in mind, one could imagine there is a vast crop of options available right now. This makes understanding what will actually work that much more difficult.

The Key Ingredients You Should Look for in Hair-Growth Products
Whether you’re looking to prevent or treat hair loss, your first step may be consulting with a trusted dermatologist or trichologist to determine the root cause and create a plan of next steps. Saedi recommends prostaglandin analogs to help promote growth or supplementing your diet with biotin. Aside from prescription formulas, Hodgdon is partial to clean, plant-based actives, which are at the heart of Vegamour’s lineup. “I recommend using products that ensure these actives are bio-available (readily absorbed by the body) and included at effective levels,” he says.
Below are hair-growth products that experts recommend to help boost your hair-growth potential.

Best Cleansing Duo: Vegamour Revitalising Shampoo and Conditioner
Vegamour’s Gro Revitalising duo is powered by natural actives of mung bean, curcumin, and red clover to support longer, denser hair. What’s more, there’s vegan keratin, silk proteins, marula oil, organic murumuru butter, and ximenia oil for a nourishing, strengthening cleanse and condition. Think of this as the ultimate start to any hair-growth regimen.

Best Capsule Supplement: Nutrafol Hair Growth Supplement
Saedi says that those in search of a hair loss treatment as a result of a deficiency (such as vitamin D, iron, or zinc) can benefit from ingestible supplements. “Ingestibles may not work for everyone experiencing hair loss, but it can’t hurt,” she notes. These supplements by Nutrafol are one of her favourites. “[This] has vitamin E, which has been shown to help with hair loss and hair damage caused by oxidative stress, which is an imbalance between free radicals and antioxidants in your body.”

Best Strengthening Oil: Mielle Rosemary Mint Strengthening Oil
Mielle’s scalp and hair oil is known to promote stronger, healthier tresses through a powerhouse blend of rosemary, mint, and biotin. The trio, working in tandem with a blend of 30 essential oils and extracts, comes together to condition hair follicles, relieve dry scalp, smooth split ends, and enhance hair elasticity.

Best Pre-Cleanse Oil: Act + Acre Scalp Detox
“An amazing way to promote growth is by implementing a weekly scalp oil into your routine,” says Reavey, with Act + Acre’s Scalp Detox in mind – describing it as “an easy-to-use, pre-cleanse oil that gently breaks down sebum, removes buildup, and restores balance to the scalp.” In fact, Vogue’s senior beauty editor, Lauren Valenti, previously wrote that its blend of botanical oils, moringa extract, and baobab and basil leaf transformed her curls.

Rahua’s Blend Scalp & Hair Treatment
“Healthy hair starts with a healthy scalp,” notes Saedi of her approach to spurring growth, starting with a good cleanse and condition, notably Rahua’s hair-care products. “I especially recommend [its] Blend Scalp & Hair Treatment to patients dealing with an itchy, irritated scalp because its anti-inflammatory effects are known for soothing the scalp and strengthening the hair follicle.” The treatment, which features a blend of plant-powered botanicals from hemp and peppermint oil to green tea, not only stimulates the follicle but balances the scalp.

Best Scalp Serum: Grow Gorgeous Hair Density Serum
Grow Gorgeous’s hair growth serum relies on a blend of caffeine, hyaluronic acid, pea sprout extract, and Chinese skullcap to stimulate hair follicles while delivering hydrating and antioxidant benefits essential to a healthy scalp. In my experience testing this topical solution, I saw growth along my edges in a matter of weeks – though I applied to my entire scalp, too.
