Mielle Organics Rosemary Mint Scalp and Hair Strengthening Oil

$9 at Amazon

Amazon’s best-selling hair growth oil—which has been purchased more than 80,000 times in the past month alone—is a mere $9 ahead of Black Friday. True to its title, the formula stars rosemary oil, which stimulates hair growth by improving scalp circulation. One shopper, who had experienced hairfall prior to trying the oil, said they “barely shed at all” since incorporating the product into their routine.

Redken Extreme Lengths Shampoo

$15 at Amazon

Hailing from a Sabrina Carpenter-used salon brand, this shampoo bolsters breakage-prone strands. By fortifying weak hair, the formula stymies shedding—which, ultimately, equals longer, healthier hair over time. Castor oil, a nutrient-rich extract prized for its ability to spur new growth and boost hair health, is present. So, too, is biotin—a B vitamin and humectant that softens and smooths roughness.

Kitsch Rice Water Shampoo Bar for Hair Growth

$11 at Amazon

If you’ve yet to try solid shampoo, this shopper-loved option from Kitsch is an excellent starting point. Spiked with rice water—a protein-rich ingredient used for centuries to maximize hair health—it encourages new growth while nurturing existing hair and adding shine. One fan with alopecia said their hair is “growing faster than ever” since incorporating Kitsch’s solid shampoo into their routine.

Aromatica Rosemary Root Enhancer

$13 at Amazon

This under-the-radar, drug-free Korean hair growth serum is packed with rosemary extract—which, per studies, has been shown to rival minoxidil (the active ingredient in Rogaine) in effectiveness. Lightweight and mistable, the elixir smells like a spa and feels refreshing—not greasy—on the scalp.
