Reasons to buy

Relief for dry, flaky, itchy scalps, noticeably less breakage and smoother strands with consistent use, the invigorating rosemary-mint scent, and the ~$10 price with a convenient dropper bottle.

Reasons to skip

It's heavy — fine and straight hair report grease and weigh-down, doing better with it as a wash-out pre-shampoo than a leave-in.
Separately, a proposed 2024 class action alleges hair loss in some users; the allegations are unproven and the case is ongoing.

The viral rosemary oil earns its following on a specific profile: thick, curly, coily or wavy hair with a dry, flaky or itchy scalp. Those users report the consistent wins — a tingly, soothed scalp, noticeably less breakage over weeks of use, smoother strands — delivered by a rosemary-mint-biotin blend at around $10 with a dropper that makes scalp application easy. Fine and straight hair is the wrong match: the oil is heavy, and lighter hair types report grease and weigh-down unless they use it as a rinse-out pre-shampoo treatment. Honesty also requires the wider context: a proposed class action filed in late 2024 alleges the oil caused hair loss for some users — allegations that remain unproven in an early-stage case, with no ingredient officially blamed. And temper the growth claims: less breakage helps you retain length; dramatic regrowth is not an established effect.

Most common complaint

It's heavy — fine and straight hair report grease and weigh-down, doing better with it as a wash-out pre-shampoo than a leave-in. Separately, a proposed 2024 class action alleges hair loss in some users; the allegations are unproven and the case is ongoing.

Worked best for

Thick, curly, coily and wavy hair with dry or irritated scalps, used as a scalp massage or pre-shampoo oil. Worked worst as a leave-in on fine, straight hair.

Frequently asked questions

Does Mielle Rosemary Mint Oil grow hair?

It's marketed for strengthening, and buyers report less breakage — which helps retain length. Dramatic regrowth claims aren't substantiated, and a pending 2024 lawsuit even alleges hair loss for some users (allegations remain unproven).

How do you use it?

Apply with the dropper directly to the scalp and massage in, or use it as a pre-shampoo/hot-oil treatment. Fine-haired users generally wash it out rather than leaving it in, to avoid greasiness.
