Four Stages Of Hair Growth

Hair has two types structures 

first, the follicle itself, which resides in the skin,  and second, the shaft, which is what is visible above the scalp.Hair on the scalp grows about .3 to .4 mm/day or 6 inches per year. hairs will be in one of three stages of growth and shedding: Anagen, Catagen, and Telogen . Each phase has its own timeline, which can be affected by age, nutrition, and overall health.




 Anagen (Growing phase)


The cells within the root are active and new hair is build up. As long as the papilla remains in good condition this process will remain active for 1-7 years, with an average growth rate of 1cm per month.

Catagen (Transition phase)

A period of transition takes place over the procedure of 2-3 weeks – growth stops and the hair root becomes separate from the papilla.

Telogen (Resting Phase)

The resting phase that continues for a period of 3-4 months – during this period the papilla rests and without a supply of nutrients, the existing hair root shrinks, leaving space for new hair growth within the follicle.


Re-Growth
The papilla reactivates and a new hair starts to grow, pushing the old hair out of the follicle – the process of shedding hair is inevitably sped up by day-to-day washing, brushing and drying.
