The chemical structure of jojoba oil resembles sebum, the natural skin oil produced by the sebaceous glands. Sebum moisturizes the scalp and helps reduce hair loss. Jojoba oil readily penetrates the hair follicles, dissolves the build ups and frees the follicle for further growth. It also works as an antiseptic as it heals the bacteria on the scalp. Jojoba oil is effective in treating dry and scaly scalp.
