Will this actually add volume?

Expect softness and shine more than lift. Castor oil coats the hair shaft, which can make roots look flatter, especially on fine hair. Use a small amount on the ends and mid-lengths if volume is your goal.

Can I use it on my scalp?

Yes, the directions say to massage it into the hair or scalp until absorbed. It suits dry, tight scalps, but if you are prone to buildup or dandruff, use it sparingly and wash it out regularly.

The instructions describe massaging it in until absorbed, with no rinse step. Treat it as a leave-in and use a small amount, since castor oil is thick and a little goes a long way.

Is it good for fine or thin hair?

Use it cautiously. Fine hair tends to look greasy and limp under heavy oils. Apply a tiny amount to the ends only, or use it as an overnight scalp treatment before washing.

How long will a 50g jar last?

That depends on use. As a spot treatment on ends or scalp it lasts a while; as a full-head application several times a week it will run out quickly, so it is better suited to targeted use.

Is it different from plain castor oil?

The formula is built on castor seed oil, so the core effect is similar. A dedicated product may add other conditioning ingredients and a lighter texture, but no full ingredient list is provided here.

Our take on the Volumizing Nourishing Hair Treatment

This is a 50g leave-in hair and scalp treatment built around castor seed oil, sold as a volumizing and moisturizing product for all hair types. It is a small jar meant for massaging into the scalp or hair until absorbed, so it suits people who want a simple daily or travel-sized step rather than a full wash-day routine. Castor oil is a heavy, occlusive oil, so it adds shine and softness more reliably than lasting volume, and fine or thin hair can look weighed down if too much is used. Compared with lighter scalp serums and volumizing mousses, it is oil-based and richer, which helps dry scalps but works against lift at the roots.
