How sebum works to protect your hair

Sebum is an oily substance produced by your body to protect your hair. It is a protective coating on the surface of the skin or scalp to hydrate it and protect it from bacteria and fungi which cause damage to your hair.  

How is sebum produced? 

Sebum is a natural oil produced by the sebaceous glands highly present on the face, scalp, and chest region. It travels through the follicular ducts that connect the gland to the hair follicle. The growing hair pulls the sebum up and onto the surface of the skin and makes it look greasy or oily. Typically, your hair becomes greasy within 24 to 48 hours (about 2 days) after washing with a mild shampoo.  

We all understand the importance of hygiene and taking a shower regularly, but it is a different story when it comes to hair care. Every time you wash your hair, you wash away the natural sebum oil, and your body sends signals to produce more sebum. If you wash your hair daily, you will see your hair becoming greasier more quickly. 

Sebum production can fluctuate for many reasons, hormone changes being the biggest one. An underproduction of sebum can cause dry and flaky scalp. Increase water intake and limit the use of shampoo to keep sebum production in control.  

What are the health benefits of sebum?  

• Hydration 

Sebum locks in moisture which promotes skin hydration and flexibility. 

• Antioxidant  

Sebum transports antioxidants which protect against the damaging effects of free radicals. 

• Protection Barrier  

Sebum prevents harmful bacteria and viruses from penetrating the skin because it's slightly acidic.  

• Sun Protection  

Sebum also works as a protectant against sunburn and UV rays.  

Let your hair become greasy for a while before washing as it promotes hair growth. If you wear hair extensions, your hair can become knotted and dry. Using mild or herbal shampoo and all-natural organic hair oils like coconut, olive, almond, avocado, etc. can help replace sebum to some extent.
