Why does hair become drier with age?

As we age, our sebaceous glands become less and less active. The hair loses its elasticity and breaks more easily.

 

Factors such as stress, drug treatments, heat styling, coloring, sun exposure, pollution and smoking all accelerate aging. These aggressions degrade first the hair's surface, then the cuticle, and finally attack the hair fiber.

 

To avoid premature hair aging, it is therefore important to protect the hair from these external aggressions.
