Telogen EffluviumTelogen is the last of the three stages in the hair growth cycle. After growing in the anagen stage, hair enters a short transition stage, catagen, before reaching telogen. Telogen is often described as the resting stage. At the end of the telogen stage, the hair shaft falls out (the actual shedding of the hair shaft has recently been named exogen.

The Catagen Phase
The catagen phase is a short transition stage that occurs at the end of the anagen phase. It signals the end of the active growth of a hair. The hair detaches from its blood supply during the catagen phase. This phase lasts for about two to three weeks while a club hair is formed.
The Anagen Phase
Also during this phase, the cells in the root of the hair divide rapidly, adding to the hair shaft. Scalp hair stays in this active phase of growth for two to six years. At any time, about 80 percent to 90 percent of the hairs on your head are in the anagen phase. The amount of time that a hair follicle stays in the anagen phase is genetically determined. Some people naturally have longer anagen phases and can grow their hair very long, while others will never see their hair get much longer than a foot and a half. At the end of the anagen phase, an unknown signal causes the follicle to go into the catagen phase.
The Telogen Phase
After the short catagen phase, the hair is released and the hair follicle rests for three months. The club hair falls out. Typically, you lose 50 to 100 hairs per day. After three months, the follicle goes back into the anagen phase and begins to grow a new hair. It’s important to note that all hairs do not go through these stages at the same time. The reason that you don’t temporarily go bald is that, at any given moment, some hairs are in the anagen phase, some hairs are in the catagen phase, and some hairs are in the telogen phase.
Receding Hair line

A “Christmas tree” pattern of diffuse hair loss, with the “base” of the “tree” at the hairline and the “tip” of the “tree” at the center of the scalp. The women having this hair-loss pattern have difficulty parting their hair in the middle and often do a comb over to camouflage the thin area. This type is the most prevalent type of female hair loss and is easy to fix with hair transplantation because their donor area is oftentimes unaffected.

A “Diffuse” pattern of hair loss that expands throughout the top scalp. Some studies have indicated that a diffuse thinning of hair is experienced to some degree by a majority of premenopausal women and by a large majority of postmenopausal women. There is a visible pattern of thinning that affects the top scalp and often the temporal areas as well making these women less favorable candidates for hair transplant. The most common feature for female alopecia is that the involved areas can be camouflaged with coloring or “creative” styling until it reaches a certain point of decreased density.

A type of “Malepattern baldness” with preserved central density. The regular femaleshaped hairline is affected by the loss in both corners (i.e., frontotemporal triangles). These women often wear fringes (bangs) to camouflage their bald area, which sometimes can be difficult to accomplish in cases of severe recession along the hairline.
