Causes For Hair Loss

Researchers have determined that this type of hair loss is related to hormones called androgens, especially an androgen called dihydrotestosterone. Androgens are important for normal male sexual development before birth and during puberty. Androgens also have other important functions in both men and women, such as regulating hair growth and sexual desire. Trauma such as childbirth, major surgery, poisoning and severe stress can cause a hair loss known as telogen effluvium, with a large number of hairs entering the resting phase at the same time, causing detachment. The condition also occurs as a side effect of chemotherapy, while targeting cancer cells in division. This treatment also affects the hair growth phase, with the result that nearly 90% of the hair falls out shortly after the start of chemotherapy.

It usually occurs gradually and in predictable patterns: a declining hairline and bald spots in men and slimming hair along the scalp crown in women. Hair loss is a side effect of various medications taken for common health problems. Anticoagulants, oral contraceptives, depression medications, NSAIDs and beta and calcium channel blockers can lead to thinning hair or baldness.

The next anagen phase begins when new hair grows on the same follicle. Most people lose 50 to 100 hairs a day as part of this natural cycle. The most common cause of hair loss is a hereditary condition that occurs with aging. This condition is called androgenic alopecia, male pattern baldness and female pattern baldness.

The 5% group was superior to the 2% group in terms of the initial peak in capillary weights. However, all groups showed a gradual decrease of 6% per year in hair weight during the treatment period. This would mean that patients taking minoxidil as monotherapy for MAA remain bald despite treatment. If treatment is stopped, the positive effect on hair growth will be lost within 4-6 months .

Alopecia areata is a common autoimmune skin disease that affects up to 6.8 million people in the United States. This disease causes the immune system to attack the hair follicles, which can lead to complete hair loss on the scalp and, in extreme cases, throughout 防脫髮洗頭水 the body . During the catagen phase, the hair stops growing and separates from the follicle, the structure under the skin that keeps the hair in place. During the telogen phase, the follicle rests for two to three months and then the hair falls out.

It is known as androgenetic alopecia or, more often, pattern baldness. And although the ancient Greek doctors made a first stab to explain what causes baldness, it was not understood until 1949. Minoxidil is an approved freely available drug for male pattern baldness and alopecia areata. Some people have an allergic reaction to propylene glycol in minoxidil solution and a minoxidil foam without propylene glycol has been developed. The longer the hair no longer grows, the less likely the minoxidil will regrow. Any screwed hair and any hair that can be lost is lost while using Minoxidil.

However, it is not clear how these genetic changes increase the risk of hair loss in men and women with androgenetic alopecia. A variety of genetic and environmental factors are likely to play a role in the cause of androgenetic alopecia. While researchers study risk factors that may contribute to this condition, most of these factors remain unknown.

A daily dose of milligram oral finasteride decreases the DHT scalp by 64% and the DHT serum by 68% . Finasteride was originally administered for benign prostatic hyperplasia at 5 mg daily. In practice, finasteride can be administered at a dose of one milligram per day or at longer intervals. A five-year multinational study of the effect of finasteride on treatment with MAA found it superior to placebo . The placebo group suffered a progressive decrease in hair count and lost about 26% of terminal hair compared to baseline counts at the end of the 5-year study. In contrast, patients with finasteride experienced a 10% increase in hair at the end of the first year.

It is important that the physician addresses patients’ emotional responses to alopecia, including anger, anxiety, and depression, including their belief about the impact of their condition . The main pathophysiological features of MAA are reduced hair cycle development, follicular miniaturization and inflammation. In MAA, the anagen phase decreases with each cycle, while the length of the telogen remains or continues to be constant.

A decrease in hair count was observed 12 months later, demonstrating the reversal of the beneficial effects of treatment during the first year. Androgenetic alopecia in men has been associated with several other medical conditions, including coronary heart disease and an enlarged prostate. In addition, prostate cancer, insulin resistance disorders and high blood pressure have been associated with androgenetic alopecia.
