The $15 Botanic Hearth Biotin Shampoo is a nutritive hair wash that creates the illusion of fullness and body in a single use. Better yet, the formula strengthens weak strands and spurs new growth in as little as a few weeks, per fans. Devoid of hair growth drugs like minoxidil (which poses potential side effects), Botanic Hearth’s shampoo is instead powered by potent plant extracts.

Key among them is rosemary, which has garnered ample buzz as a natural alternative to minoxidil; in fact, the herb rivals the over-the-counter hair loss drug as a growth agent, studies have shown. As dermatologist Dr. Marisa Garshick, M.D. previously explained to InStyle, rosemary increases “circulation in the scalp,” delivering nutrition to hair follicles and encouraging new growth. Additionally, rosemary strengthens existing strands, Dr. Garshick added, and can quell shedding as a result.

Of course, the Botanic Hearth Biotin Shampoo also contains its titular ingredient. Despite its association with hair growth, however, biotin has little scientific evidence supporting its effectiveness in this domain. That said, biotin does provide hydration, which prevents dry, brittle hair from snapping. Finally, the shampoo features turmeric, an extract that mitigates certain types of hair loss by virtue of its antiinflammatory properties. 

Perhaps even more compelling than its ingredients? Anecdotal evidence from shoppers who swear Botanic Hearth’s shampoo wholeheartedly delivers on its claims. One reviewer who purchased the formula to stymie their “shedding” saw new growth within one week, while another with “thinning” hair said they’ve “stopped shedding” entirely thanks to the shampoo. A final fan whose hair had been “falling out” reported “a big difference” in fullness after using the shampoo for only a month—and they have the photos to prove it.
