Imagine a middle-aged man who has just turned 30, who is at the peak of his career. His mature charm is evident, and the happiness of his family is also admired by others. However, the trouble of hair loss makes them suffer unbearably. Due to long-term work and life pressure, hair loss is very common among middle-aged men and has become one of the focuses of attention.
In recent years, with the rapid economic development, people have increasingly high requirements for image, especially for successful people who have just entered middle age. Their career development is smooth, but their hair is increasingly sparse. So what is the reason for male hair loss? The following is a detailed introduction.
There are many reasons for male alopecia, and the most common is male type alopecia, also known as seborrheic alopecia, androgenic alopecia, or premature baldness, which accounts for more than 90%. This is mainly due to genetic factors and elevated concentrations of dihydrotestosterone (DHT), a substance in the scalp. DHT is a metabolite of testosterone (T), composed of 5 α Reductase induction. After binding to androgen receptors in the scalp, it enters the nucleus to control the growth process of hair, shortening the hair growth cycle, causing progressive microminiaturization (degeneration) of affected hair follicles, reducing the proportion of hair follicles during growth and degeneration, and making it difficult for degraded hair follicles to grow hair again.
Currently, the commonly used grading method for male type alopecia in the world is Hamilton classification, which is divided into 7 grades and 13 types of alopecia, of which grades 1-5 belong to mild to moderate alopecia, and the hair follicles have not yet completely atrophied; Grade 6 or above belongs to severe alopecia, with most hair follicles already atrophic. In addition, male type hair loss is commonly seen in men in their 30s and 40s, and there are also cases of baldness around the age of 18. If not treated promptly, the longer the duration, the more severe the hair loss.
