How long does the telogen or resting stage of hair growth last?

The telogen phase, also known as the resting stage of hair growth, is a critical part of the hair growth cycle. This stage typically lasts for around 3 to 4 months, during which the hair follicle remains dormant. At the end of this period, the hair is eventually shed, making way for new growth to occur in the anagen (growth) phase.

Understanding the hair growth cycle is important for hairstylists, as it impacts hair health and the timing of treatments. Knowing that the telogen phase lasts about 3 to 4 months helps in managing client expectations regarding hair shedding and regrowth, as well as in assessing the overall health of their hair.
