Is this a rosemary oil or a castor oil blend?

Castor seed oil and coconut oil come first in the formula, with rosemary as part of the blend. Treat it as a conditioning hair oil, not a concentrated rosemary scalp serum.

Can I use it on fine hair?

Yes, but start with one or two drops on the ends only. Coconut oil can weigh down fine or low-porosity hair, so keep it away from the roots.

Should I apply it to wet or dry hair?

The instructions call for dry hair. Apply a few drops to the scalp or ends, massage until absorbed, and leave it on.

Do I need to wash it out?

It is a leave-in oil. If your hair looks greasy, use less next time or rinse it out before styling.

How much is in the bottle?

100ml. With a few drops per use, that covers months of regular application.

Will it help with an oily scalp?

It is marketed for oil control, but oils can add weight at the roots. Use it on ends and mid-lengths if your scalp is already oily.

Our take on the Rosemary Hair Care Oil

A 100ml leave-in hair oil built on castor seed oil, coconut oil and vitamin E, sold as a scalp-and-ends treatment for oil control, detangling and nourishment. It is a lightweight blend aimed at everyday use rather than a deep treatment, and it suits people who want one bottle for both scalp massage and dry ends. Against heavier single-oil products like pure castor or argan oil, it spreads more easily and rinses cleaner, but it carries less concentrated rosemary than dedicated rosemary scalp serums. Reviewers of similar blends praise the softness and slip on ends and question how much rosemary the formula actually contains.
