The telogen phase typically lasts around 3 months. I say this because the hair does not look bent or shriveled at the root catagen phase. A Sustaining the anagen follicles intense proliferation and protein synthesis efforts requires significant ATP hydrolysis whereas the telogen follicles relative proliferation and translational quiescence is much less energetically expensive.
How the cycle works. Normally up to 90 of the hair follicles are in anagen phase while 1014 are in telogen and 12 in catagen. This means that body hair is not permitted to grow for very long when compared to scalp hair and also spends more time cut away from the blood supply too.

It is generally the longest phase and is followed by catagen. The growth phase in the hair growth cycle during which a newly formed hair continues to grow. Telogen Phase This phase is the resting period where no new cell division occurs.
The scientific terms for the hair growth phases are anagen catagen and telogen. These hairs tend to be weaker and less pigmented. From the surface anagen hairs tend to be stronger in hair shaft tensile strength and more pigmented that is these hairs have more melanin.
Telogen Phase and Body Hair In addition to having a shorter anagen growth phase body hair typically stays in the telogen phase for much longer than hair on the scalp. Tap again to see term. There are two main categories of hair growth disorders.

During the anagen phase a hair bulb forms at the bottom of the hair follicle and matures into a full-length strand of hair that grows outwards past the scalp barrier. A short transitional phase of the hair growth cycle between anagen and telogen that usually lasts between 10 to 20 days and during which the lower portion of the hair follicle regresses and hair growth ends Anagen is followed by a regressive stage called catagen of about two to three weeks then a resting stage telogen of about three months.
Catagen is the transitional phase of the hair follicle from the active growth phase anagen to the resting growth phase telogen in the hair growth cycle. The active phase of the hair growth cycle that precedes catagen and telogen that is marked by rapid division and differentiation of cells in the lower portion of the hair follicle and by lengthening of the hair shaft and that typically lasts between two to six years. The catagen phase is the second part of a hairs lifecycle.
