The chemical structure of jojoba oil resembles sebum, the skin's natural oil produced by the sebaceous glands. Sebum hydrates the scalp and helps reduce hair loss. Jojoba oil easily penetrates hair follicles, dissolves buildup and frees the follicle for further growth. It also acts as an antiseptic as it cures bacteria present on the scalp. Jojoba oil is effective in treating dry and flaky scalp.
