When it comes to hair loss, topical minoxidil — the active ingredient found in popular over-the-counter drugs such as Rogaine — is one of the most clinically proven and expert-endorsed solutions for hair growth. That said, the drug is not without some drawbacks for some people.Minoxidil belongs to a class of drugs known as vasodilators, which, while generally well tolerated, may contribute to a fast heartbeat in rare cases. Others abandon the treatment altogether because it can be bothersome to apply to the scalp every day, and some people report itching, flaking or an unpleasant texture.While minoxidil is the only hair-loss drug that’s FDA-approved for both men and women, there are alternative products that can help combat hair thinning by creating the optimal conditions to support hair growth.Ahead, we compiled a list of these products using recommendations from trichologists and board-certified dermatologists, reviewers and previous HuffPost coverage. The experts consulted for this story do not necessarily endorse the products ahead unless otherwise noted.AmazonA biotin-infused shampoo Maple Holistics is a lesser-known hair care brand, but the biotin shampoo stands out because it contains biotin plus rosemary oil, evening primrose oil and jojoba. This combination of ingredients encourages hair growth by nourishing the scalp and hydrating the hair strands. Even from the first wash, users of the Maple Holistics formula claim their fine hair looks and feels instantly thicker, more volumized and healthier, without having to add extra steps or products into their existing routine. With extended use, others are saying they’ve noticed a significant reduction in the amount of hair that falls out during washing, quicker hair growth, and, in some cases, even new hair growth in areas around the hairline where there was previous sparseness.AmazonA budget-friendly scrub with soothing ingredientsDermatologists previously explained to us the potential hair growth benefits of using a scalp scrub, a simple product addition that, while not normally a direct hair growth treatment, does help create more favorable conditions for optimal hair growth."Soothing ingredients like aloe, tea tree, or peppermint help calm irritation and support a balanced scalp environment," board-certified dermatologist Dr. Divya Shokeen previously said. She also said she prefers sugar-based scrubs over large, coarse physical exfoliants because they dissolve easily with water, which helps prevent over-scrubbing, and provide controlled mechanical exfoliation without being too abrasive.Based on Shokeen's guidance, we selected the Mielle rosemary mint clarifying sugar scrub, the brand behind the ultra-viral hair-strengthening oil (see below) that many users claim has improved their hair growth. Just like the reviewer-beloved oil, the scalp scrub also contains rosemary oil, which can potentially accelerate hair growth by improving blood circulation in the scalp, thereby stimulating hair follicles, as well as nourishing hydrators like shea butter.AmazonA viral hair strengthening and scalp oil The viral Mielle oil is a rosemary mint scalp and hair strengthening treatment that, in years past, has become TikTok-famous for its anecdotal claims surrounding improved hair health and growth. (It’s Amazon’s second-best seller in the beauty and personal care category.) The biotin-infused formula contains nutrient oils, including jojoba, grape seed and evening primrose, all of which can address dryness and brittle-feeling hair along with other scalp health factors that can affect hair retention.AmazonAn exfoliating scalp mask by a trusted name in hair growthThis is another scalp scrub, suggested by one expert (founder of Radiant Dermatology Associates, Dr. Dara Spearman). The Nutrafol Build-Up Blocker Exfoliating scalp mask, which she said is suitable for all hair types, is especially beneficial for those prone to oily scalp or hair thinning. You may already be familiar with the Nutrafol name, as it's a brand that's become a fast favorite for treating hair loss with its line of supplements."It's formulated with [fruit-derived] alpha hydroxy acids and jojoba esters to control oil production and remove dead skin cells," Spearman said, which are typically glycolic or lactic acids that gently exfoliate dead skin cells, encourage cellular turnover and improve overall scalp texture.Intended to be used more like a rinse-off mask rather than a scrub, this treatment also contains expert-recommended glycerin for hydration and amino acids, which can help strengthen hair strands.AmazonA DHT-blocking shampoo"Dihydrotestosterone (DHT) is a hormone thought to be responsible for hair shrinkage and loss," Camp previously said. "This shampoo is formulated with saw palmetto, a botanical ingredient that is thought to inhibit the activity of DHT and promote hair growth."Endorsed by the American Hair Loss Association, this clinically developed shampoo claims to target three different zones of hair loss, including those from inflammatory and nutritional causes.AmazonAnother DHT-blocking shampoo with biotin and pumpkin seed oilThe Pura Dor shampoo is an additional DHT-blocking option that's been well-received among its users. It's an aloe vera-based formula containing saw palmetto, nourishing argan oil and tons of other hair-loving ingredients. It also features the inclusion of pumpkin seed oil, an ingredient that dermatologists have previously said might be helpful for some people experiencing hair thinning. AmazonA viral silicone-bristled scalp massagerFormer shopping writer Haley Zovickian previously wrote about how this viral shampoo brush and scalp scrubber has made her hair cleaner and reduced the appearance of flakes. According to Los Angeles-based trichologist Anna Asarte, who previously spoke with HuffPost about the things you should never do if you're suffering from hair loss, the massager can also stimulate blood flow, which helps promote the health and growth of follicles. Reviewers agree that this silicone-bristled brush has created new hair growth, while also extending the amount of shampoo required to create a full and satisfying lather. AmazonA widely revered liquid multivitamin for thicker hairAmazonA "gold-standard" dandruff shampooExperts regularly sing the praises of the reviewer-beloved Nizoral shampoo, a "gold-standard" of dandruff treatments, according to one dermatologist."The active ingredient in this dandruff shampoo is [1%] ketoconazole, which has antifungal properties," Camp explained. And although he admits that evidence is limited, ketoconazole may help to reduce inflammation and the hormonal influences that can contribute to hair loss, in addition to helping to alleviate dandruff.And if you're traumatized by other medicated anti-dandruff shampoos in the past, reviewers assure us that, unlike other market options that smell unpleasant, are harsh on hair and can have it feeling dry and gunky, Nizoral leaves tresses soft and clean-smelling.AmazonA red light therapy cap Board-certified dermatologist Dr. Brendan Camp (among other experts) previously regaled the effectiveness of red light therapy on hair growth. According to him, "low-level light therapy (LLLT) makes use of the biological effect of light on hair follicles," and this impact on the mitochondria inside hair follicles can ultimately lead to increased cellular energy and protein production.Based on this knowledge, we've previously covered the iRestore treatment helmet, an FDA-cleared laser system that uses 282 lasers and LED lights to stimulate hair follicles for new growth. According to the brand, this hands-free device uses an optical wavelength, can be used to maximize the results of other hair loss treatments like minoxidil (if you choose to use it) and can be useful for conditions like alopecia, receding hairlines, pattern baldness and thinning hair.
