Hair oil is a product used to nourish and moisturize hair. It is typically made from natural oils, such as coconut oil, argan oil, or jojoba oil, which help to improve hair texture and shine. Applying hair oil can also reduce frizz and protect hair from damage caused by heat styling or environmental factors. Many people use hair oil as part of their hair care routine. It can be applied before washing hair as a treatment or used as a finishing product to add shine. Regular use of hair oil can promote healthier hair growth and maintain overall hair health.
