Our hair care oil contains mineral oil and castor seed oil. It promotes better absorption by the scalp, resulting in healthy hair; the massager accurately delivers the oil to the hair roots, providing a comfortable experience with gentle massage. It's easy to use: 1. Cleanse your scalp and hair. 2. Pour an appropriate amount of oil into the massager and gently massage it onto your scalp. This hair care oil prevents hair loss, promotes hair growth, moisturizes hair, and strengthens hair.
