What is menthol?
Menthol is a clear or white organic compound that is derived from peppermint oil. It creates a cooling effect by penetrating the skin and stimulating the skin's nerve endings.
Mentholated products increase blood flow to the skin. Increasing blood flow to the scalp skin encourages healthier hair growth.
Menthol is used in hair products to alleviate common scalp problems like itching, dryness, and tightness associated with scalp conditions like psoriasis.
Hair Oil Regulation
Menthol is often included in hair preparations to help reduce scalp oiliness from excess sebum production. Sebum is the oil that is naturally produced by the skin.
While most people experience few side effects from using mentholated hair products, severe allergic reactions can occur. If you notice scalp irritation after using a hair shampoo, ointment, or lotion containing menthol, see a physician immediately.
