You can potentially help increase eyebrow hair growth with two ingredients: (1) bimatoprost, the active ingredient in Latisse; and (2) minoxidil, the active ingredient in Rogaine, says dermatologist Marisa Garshick. In a small-scale study, patients noticed increased hair density after coating their brows with .01 percent bimatoprost lotion (similar to the .03 percent bimatoprost in Latisse) once a day for six months.
Similarly, in another small-scale study, patients saw thicker brows after applying 1 percent minoxidil lotion to their eyebrows twice a day for 16 weeks (though please don’t rub Rogaine on your brows, unless you want major irritation). Still, more studies are needed before dermatologists can conclude whether or not these ingredients directly increase eyebrow-hair growth.
In the meantime, other topicals, like antioxidants, peptides, and moisturizers, can be helpful in your journey to thick, bushy brows. “Peptides, vitamins and antioxidants may help to strengthen and improve the overall texture and quality of the brows,” says Dr. Garshick, “which can improve the overall appearance, but may not specifically grow eyebrow hairs.”
