Question 9

Describe and name the hair cycles

Answer 9

1. Anagen: Growing phase
   It’s the longest phase, lasting about 3 to 5 years for the hairs on your head, could continue growing for 7 or more years.
2. Catagen: Transition phase
   starts when the anagen phase ends, and tends to last about 10 days or so. During this chapter, hair follicles shrink and hair growth slows.
3. Telogen: Resting phase
   typically lasts around 3 months. An estimated 10 to 15 percent of your scalp hairs are in this phase.
   Hairs don’t grow during the telogen phase, but they don’t usually fall out either.
4. Exogen: Shedding phase
   essentially an extension or a part of the telogen stage of hair growth. Losing 50 to 100 hairs per day during the exogen phase is normal.

can last about 2 to 5 months, new hairs are growing in the follicles as old hairs fall away.
