What’s Normal About Hair Loss?
It is important to note that spillage of the fur is a natural process with 100 to 300 hair follicles that are randomly laid each day. In this article we will look at two different aspects of normal hair loss. First, we will examine what actually takes place in the hair growth cycle. Second, we assess the progression of hair loss over time.
The hair consists of long, twisted keratin fibers protected by a coating of keratinized cells. Just below the surface of the skin is a cluster of active cells known as dermal papillae, from which the hair grows into the root.
This growing fiber eventually hardens and grows from the head skin. At this stage, the hair fiber is only dead with the root, which contains living cells.
The hair enlargement cycle consists of three different stages in more detail:
1. Anagen phase – a growth process that lasts for two to seven years. On average, each hair grows about 6 inches (15 cm) per year.
2. Catagenic phase – a transition phase that lasts about two to four weeks. The hair shaft separates from the dermal papilla and moves within a shrinking follicle.
3. Telogen phase – a rest period of about three months, allowing the follicle to leave before the hair falls. Thereafter, the cycle repeats itself until other factors intervene to prevent the cycle from repeating.
Obviously, for men and women, hair loss has a role in the development of time. People are born with soft and thin body feathers in various quantities. Over time some of these hair become stronger and develop other features such as color and texture. The pubic hair is characterized by a low spread in the forehead until the beginning of puberty. For men, it only lasts a few more years.
As the men progress in their twenties, the hairline recoils into the frontal temporal region, and elsewhere has a more mature appearance with slight thinning. This concave appearance is not equal to premature calf, all of them are degrees.
The Norwood Scale is an extremely useful tool to develop a hair growth strategy as it allows you to create your own hair loss profile as understood by physicians and other hair loss specialists. Even more important, it can help you to listen to your mind and help you distinguish between normal hair loss that does not require corrective action and excessive loss that needs to be acted on immediately.
