Mielle Organics Rosemary Mint Scalp & Hair Strengthening Oil, 2 fl oz

On the scalp. Use the nozzle to part the hair into rows, run a thin line along each part, then massage it in with your fingertips. Any oil left on your hands can be smoothed over the ends.

No. It is a leave-in oil, so you apply it and go. Most people use it two or three times a week and shampoo on their normal schedule.

Only if you overdo it. The oil is thin, and a few drops per section is enough for a full scalp. Fine hair usually does better with a smaller amount applied at night.

Yes. The formula has no sulfates or mineral oil and is intended for all hair types, including chemically treated and relaxed hair.

That is the peppermint oil. A light cooling sensation on the scalp is normal. If it feels sharp rather than cool, use less and keep it off broken or irritated skin.
