Moisturizing hair, defined as replenishing moisture in the hair shaft, is an essential practice for hair health. Like how a plant benefits from watering, hair benefits from moisture to maintain its elasticity and strength.
Moisturized hair is less prone to damage, breakage, and dryness. Historically, oils such as coconut oil, olive oil, and argan oil have been used to moisturize hair. These oils penetrate the hair shaft and provide deep conditioning.
