Our follicles are attached to sebaceous glands, which make oil called sebum to add moisture to the hair.

It also dissolves sebum, an oily, waxy substance produced by the sebaceous glands near your hair follicles.

But instead, the culprit in the saliva is a protein called Fel d1, which is produced in a cat's salivary and sebaceous glands.

Spots and breakouts are common during high temperatures because there is an excess secretion of oil from our sebaceous glands.

Mammals have three types of sweat glands: apocrine, sebaceous and eccrine.
