Male Pattern Baldness Causes
Hair Growth Cycle:
Hair Growth Cycle Hair grows from follicles which look like tiny pouches which we have just under the surface of our scalp skin. The life cycle of hair is normally a three year cycle and continues to grow in that pattern. Hair grows from each follicle for around three years. It then falls off and a new hair grows from the same follicle. This cycle of hair growth, hair falling and new hair growth continues throughout our lives.
Causes of Male Pattern Baldness
Male pattern hair loss is commonly referred to as androgenic alopecia or male pattern baldness. It is a genetic trait that is generally related to hormones in both males and females. Imbalance in a particular hormone called dihydrotestosterone (DHT) in the scalp can lead to a decreased growth pattern of the hair follicle, which leads to reduced production of hair and weak hair growth. This hormonal imbalance is a major cause of male pattern baldness. Anyone who has a genetic history of this hormonal imbalance that causes male pattern baldness, is liable for it to continue in them. In other words, if your forefathers have suffered from male pattern hair loss, that hereditary that you carry forward, could be a cause for male pattern baldness in you.
Male Pattern Baldness – Follicle Shrinkage
In male pattern baldness, the patient starts losing hair due to the shrinking of the hair follicle. The result ends in the follicle becoming weak and the hair that grows is shorter and finer, or absolutely no hair growth at all. In some cases, in spite of the hair follicle being alive, the hair simply stops growing. This depletion of the hair follicle is the most common cause of male pattern hair loss and on an average, affects up to 70% of men with male pattern baldness.
The following are a few of the causes that contribute to male pattern baldness:
- The hair follicles that get affected gradually become smaller in size than than normal, causing less space for the hair to grow. This results in partial or improper growth of the hair follicle and eventually leads to male pattern baldness over a period.
- When the follicle shrinks, every new hair that grows is thinner than the previous one that falls off and the period of hair growth reduces slowly. This kind of hair thinning and follicle shrinkage is a strong symptom of having male pattern baldness.
- This results in a much smaller hair follicle and a thin weak hair that does not grow out to the surface of the skin which is a major contribution to male pattern baldness.
Male Pattern Baldness Symptoms:
The pattern of male baldness typically begins at the hairline. A regular hair loss pattern where the hairline starts reducing forming an “M” shape on the scalp. The hair grows thinner and shorter, and creates a U-shaped pattern of hair on the sides of the head.
