Understanding Hair Growth Cycles and Hair Loss

We all lose a particular amount of hair every day – anywhere from 50 to 100 to 125 hairs. True hair loss occurs when these hairs we lose don’t grow back, or when the quantity of hair we lose every day exceeds this normal range.

Hair loss can occur as a results of medications, like chemotherapy treatments or blood thinners, which may damage the telogen hairs, or stop the natural cellular division that then produces weakened hair that’s vulnerable to breaking. High doses of vitamin A also can cause hair loss also . the foremost common sort of hair loss, however, is where more and more hair follicles enter what’s called the resting phase (telogen phase) within the hair growth cycle.

Overall, hair grows continuously from the scalp, but it moves faraway from the scalp in 3 phases. Hair isn’t all uniformly in one phase. Different parts of the scalp are going to be in several phases, so at anybody time you ought to have hair follicles altogether 3 stages. Generally, most (90%) of the hair are going to be within the anagen phase, 10 to 14% of the hair are going to be within the telogen phase, and just one to twenty of hair within the catogen phase.

The first phase is that the Anagen phase, which is that the growth phase. this will last anywhere between 2 and eight years. A shorter anagen phase will limit how long your hair can grow. Hair cells at the basis divide rapidly, which lengthen the hair shaft.

In the next phase, the catagen phase, the outer root of the follicle shrinks and attaches to the basis of the hair. Hair growth stops here. This phase lasts 1 to 2 weeks.

The telogen phase is that the resting phase. This lasts from 5 to six weeks in normal hair. Hair doesn’t grow during this phase, but it stays firmly rooted within the scalp as long because the follicle stays during a resting phase below it. New growth begins at the top of the resting phase, and this is often when natural hair shedding will happen, because the new growth pushes the old hair out.

In male pattern baldness, more hairs enter the telogen phase. This effects of this are a rise in hair shedding. Hair gradually becomes thinner and shorter, and within the end, the hair follicles pack up .
