3. What are the 3 growth cycles of hair?

The growth cycle of hair consists of 3 stages:

• Anagen – It is the growing period of a hair follicle that typically lasts about 3 to 5 years.
• Catagen – At the end of the growth period, hair follicles prepare themselves for the resting phase. This stage of the hair growth cycle usually lasts about 1 to 2 weeks.
• Telogen – This is the resting period of a hair follicle. It is usually 3 to 4 months in length and at the end of this period older hairs that have finished their life will fall out and newer hairs will begin to grow.
