Hair Loss
Scalp hair loss or baldness is one condition of hair and scalp diseases that has many causes and they differ in men and women. According to studies losing up to 100-150 hairs per day is usually normal but with about 100,000 hair loss in the scalp could already be alarming. Gradual thinning is a normal part of aging but hair loss may lead to baldness when the pace of shedding go beyond the pace of regrowth, when the hair comes out in patches and when the new hair is thinner than the hair shed.
Our hair goes through a cycle of growth and rest and due to hormonal changes, damage or irritation, some hair follicles have shorter growth phase and usually produce short and thinner hair shafts. Human hair grows in three phases: the anagen, catagen and telogen. The course of each cycle differs by individual, the growing or the active phase is known as anagen. Catagen is a shorter phase wherein the hairs begin to break down. The resting phase called telogen lasts three to four months and at the end of this phase, the hair strand falls out and new hair begins to grow.
Hair loss can be a cause of some illnesses and medical conditions, medications, hair treatments and styling, poor nutrition and disruption of the hair growth cycle. But hair thinning may also be a result of predetermined genetic factors, overall aging process and family history.
This type of hair and scalp disease is quite stressful and alarming especially when you are particular about your appearance. Hair loss during the teen years is usually temporary and it generally grows back after the problems has given attention and corrected.
