* Natural Moisturizer: Sebum, the oil produced by your scalp's sebaceous glands, is a natural moisturizer. It coats the hair shaft, preventing it from drying out and becoming brittle.
* Protection: Sebum acts as a protective barrier against environmental damage, such as sun exposure, pollution, and wind. It can help to shield the hair from these stressors.
* Adds Shine: A healthy amount of oil can give hair a natural, healthy shine.
* Scalp Health: Sebum plays a role in maintaining the scalp's pH balance and protecting it from infection. It also helps to keep the scalp moisturized and prevents it from becoming dry and itchy.
Important Note: The key is balance. Too much oil can lead to a greasy appearance, clogged pores, and potential scalp issues. However, too little oil can result in dry, damaged, and brittle hair.
