The common types of hair loss in life are: 1, androgenetic alopecia, also known as seborrheic alopecia or male pattern baldness, mainly occurs in the 20-50 years old, with the change of life rhythm and work pressure, the incidence rate is gradually increasing, and the trend of low age, middle-aged and young people have become the main force of “hair loss army”. The occurrence of androgenic alopecia is related to genetics and androgens, psychological factors can trigger and aggravate the disease, and lifestyle such as staying up late, hair dyeing and perming can also seriously damage hair health. Hair loss can be controlled or even recovered by timely and scientific comprehensive treatment for patients with hair loss. Androgenic alopecia can occur in both men and women, but the performance varies. 2. Alopecia areata is a kind of sudden and limited hair loss, commonly known as “ghost shaving”. The disease can occur at any age, but is more common in young adults. The incidence is the same for both men and women. In most patients, hair loss areas of round or oval shape with varying diameters and clear borders appear suddenly on the scalp, and in severe cases, the number increases and fuses with each other to form irregular patches, or even total baldness (total loss of hair) or alopecia areata (total loss of hair along with eyebrows, eyelashes, axillary hair and pubic hair). The prognosis is generally good in mild cases, but poor in severe cases, and most cases have recurrence. The pathogenesis of alopecia areata is very complex, so you need to find the right cause and treat it according to the disease, there is no panacea for all hair loss, if the medicine is not right, it will aggravate the condition. Therefore, if you are suffering from hair loss, you must go to a professional dermatologist who treats hair loss diseases to find the correct cause of hair loss and develop the best treatment plan. Hair growth is about 0.8cm-1cm per month and damaged hair follicles need a long recovery time, so hair loss patients must keep a good attitude and stick to the treatment for at least 3-6 months to reap the joy of success. Many hair loss patients tend to suffer from the problem of being too hasty because of excessive psychological pressure, and stop persisting after 1-2 months of treatment when they do not see significant results. In fact, hair loss treatment is a continuous and coherent process, the first three months of hair loss treatment is the “danger period”, if you give up at will, the consequences may lead to shrinkage of hair follicles, which is not conducive to good treatment results.
