The Anagen phase is considered the “growth period” when the hair is actively growing. The hair bulb is anchored into the scalp providing it with nourishing blood flow. About 80-85% of your follicles are in this stage which lasts for 2-6 years. It is the best time for Hair Removal Treatments.
The Catagen phase is a short “transitional period” when the hair stops growing and the hair bulb detaches from the nourishing blood supply.
The Telogen phase is the “resting period” where the detached hair strand rests in the follicle. Hair is no longer growing but it hasn’t shed yet (about 10-15% of your hairs are in this phase). The follicle remains dormant for around 3 months while new hair growth begins to form underneath it.
The Exogen phase is the “shedding phase” where the hair finally exits or “sheds” the follicle as it begins a new anagen phase for new hair growth.
When the hair growth phases are disrupted - the Anagen “growth” phases can shorten and Telogen “resting” phases can lengthen. This answers why certain treatments may take longer to show results and why consistency of treatments is crucial.
