Numéro d’image : 13766162
| Hair follicle, illustration. Hair is formed from the protein keratin. It is a dead tissue that is pushed up by growth from the bulb at the base of the follicle, which lies in the dermis layer of the skin. To the right of the follicle is a sebaceous gland (orange). Sebaceous glands secrete an oily fluid called sebum onto the hair, which waterproofs and protects it. | |
