Mielle Rosemary Mint Scalp & Hair Strengthening Oil, 2 oz
Our verdict
Dry scalp, thinning edges, general hair sadness: two to three drops massaged in a few times a week is the whole routine. Itchy scalp goes quiet, new growth shows up around month two.
- Rosemary + mint blend
- Biotin + castor oil
- Applicator tip for scalp
- Under-$10 staple
Why we picked it
Rosemary and mint in a biotin-and-castor base sounds like a Pinterest recipe, but the formula is a genuine scalp treatment — light enough for weekly use, with an applicator tip that gets under braids and along the hairline.
We watched the edges fill in over about eight weeks of consistent use, and the tingle is the good kind — cooling, not burning. The 2-ounce bottle survives months of use. For under $10, it is the easiest yes in the hair aisle.
Best for
- Dry, itchy scalps
- Protective styles and edge care
- Fine hair that hates heavy oils
Keep in mind
- A few drops is plenty — this is not a drenching oil.
- Patch test the mint if your scalp is sensitive.
