The inside of our skin is lined with glands called Sebaceous glands. These are exocrine glands which means that they secrete substances into the body targeting specific tissues by means of ducts, whereas endocrine glands secrete substances directly into the blood by no means of ducts. (1)
These glands secrete a substance called Sebum which an oily, waxy fluid. These sebaceous glands are found concentrated mostly in the epithelial areas on the face and scalp. Thus the oily substance that is sebum is found on the surface or our face and scalp. Sebum, however, is not a bad thing for our skin, in fact, it helps to keep our skin moisturized. It provides nourishment hydration to your skin and hair and plays a vital role in its care.
However, an abundance of Sebum is not something that can be good for your skin. When you have an excess of sebum it could combine with dead skin cells, and dirt to clog up your pores. This can thus lead to Acne, whiteheads, blackheads, and other skin issues. When there is excess sebum on your scalp dandruff is one of the common issues we see.
The dry and dead skin cells on your scalp can combine with sebum to become flakes causing dandruff, this can further lead to forms of hair loss, such as hair fall, and hair thinning.(2)
Although these may seem to be problems that arise from sebum itself, you need to understand that your skin and hair needs sebum for its nourishment. Sebum is crucial for the growth and nature of your skin and hair. The problem arises when there are other things that come in the way, such as dead skin cell, dirt, or an imbalance in hormone levels.
The only time when sebum can cause issue is when there is an overproduction of it by your skin. This happens particularly when you have a hormonal imbalance. Hormones such as androgens control the production of sebum in your skin. Thus most of the time when we see an excess production of sebum is during adolescence when your hormones are all over the place. (3)
You don’t have to get rid of sebum at all, all you have to do is find the right balance in this case. As we saw that hormonal imbalance is one case, there are other times as well when there can be an excess amount of sebum secretion. This can depend on the weather as well. Sometimes a humid weather might add onto the oil on your skin, whereas a dry weather could also trigger an excess production of oil on your skin.
Something over scrubbing or washing your skin can also make it dry, this could also cause excess production of sebum, which in turn will become one of the reasons for Acne or any other skin issues that you might see.
A few things that you can do to create a balance are, wash your face not more than twice a day. Wash your hair regularly, but then again don’t over do it. Make sure you use the right products for your face, if you have oily skin stay away from comedogenic products, and lastly eat right, food rich in oil can cause a sebum imbalance.
