Rumors say: If you find that the recent frequent hair loss, indicating there may be some kidney problems.
Reply:
false. ? Male hair loss is mainly genetic factors, and the reasons for female hair loss is more complex, with the mental state and stress have a relationship. Normal hair loss need not worry, but if suddenly a large number of hair loss in the short term, we need to pay attention may be caused by conditions such as nephrotic syndrome, primary disease in need of treatment.
Demonstration:
According to the survey, one in four men will be in middle age become "bald", while only 6 percent of women suffer similar problems.
Male hair loss, to blame genetic
Although the "bald" detrimental to the overall feel manly, but in fact is precisely the cause of hair loss is a male hormone. The most common hair loss is called "androgenetic alopecia", the name sounds a bit strange, in fact, in the past called "seborrheic alopecia", "male hair loss", or "bald early." In the past we do not know the reasons for hair loss, it has been wrongly attributed to cause hair oil. In fact, hair follicles and sebaceous glands are sensitive to androgens - male hormones in the sebaceous glands can become hypertrophic, produce more and hair follicles in androgen influence smaller, thinning hair shorter birth, not to grow long enough will fall, this is the cause of hair loss.
Androgenetic alopecia and is related to genetic findings, male hair loss caused by genetic factors, the most important reason is that, with DHT (dihydrotestosterone, DHT) role. After puberty, testosterone will be with the blood circulation in the hair follicles reach the ball cells through the cell membrane into the cytoplasm, and in the cytoplasm and testosterone 5- reductase will react DHT, into the nucleus of cells to produce metabolic systems, leading to hair shortening occurs long advance into telogen.
The man with the "hair" gene, DHT receptor activity in some parts of the head of hair follicle cells is too high, it can easily be combined with DHT, affected. Forehead, top of the head and behind the occipital hair follicle cells more sensitive to DHT, so these parts of the easiest hair loss.
Female hair loss, too much pressure
Since the women themselves androgen low content of estrogen and androgen action and confrontation, so androgenic alopecia rarely occurs. The most common female hair loss is alopecia areata, we often say "receive many", unwittingly found within a small range of hair were finished off. Alopecia areata also will have more than women, men and even children can also occur.
"Receive many" more complex reasons, but most of them are with the spirit of factors, especially the anxiety caused by some unexpected turn of events, such as marital crisis, dangerous friends, depression and other emotional extreme. Some autoimmune diseases and endocrine diseases can also be associated with alopecia areata.
In 2003, the British media have to see Manchester United's game at Victoria, the opportunity to take photos of their thinning hair and baldness parts clearly visible. It is said that the week after their son narrowly escaped kidnapping of Victoria suddenly found the head of a small piece of almost no hair, then this site is also increasingly sparse. A British hair experts also said that this is because she has been a great mental stress caused.
Treatment: effective drugs, but there are side effects
For androgenetic alopecia, the medical profession found only two effective drugs, one is oral drug finasteride, which is a specific inhibitor of 5- reductase, the enzyme inhibition can hinder the conversion of testosterone to DHT , they are able to promote hair growth and prevent further hair loss.
However, finasteride has many side effects, including the feminization of male sexual dysfunction, scrotal pain, severe hair loss and its effect is not obvious.
The other is for external use spironolactone, can competitively hinder DHT receptors attached to the hair follicle, and therefore can prevent the effect of DHT on the hair follicles, but only for mild hair loss.
So, hereditary "baldness" is still a headache problem, otherwise it will not even take it all the British royal family Mozhe. Fortunately, Europe has a common male gene, so I do not even wear wigs wedding of Prince William, is also still the world live.
Normal hair loss, no need to worry
One person per day in the amount of hair loss normally 30-100 roots, studies have found that women in July and November, the most severe hair loss, this seasonal hair loss, hair loss as pets, like Do not worry, as long as the season, a lot off hair phenomenon will disappear. Some wasting disease, such as high fever, work stress, burn the midnight oil may cause hair loss in the short term, but after the removal of these incentives, can restore itself.
If a lot of hair loss for two consecutive months or more, it may be caused by other diseases, such as nephrotic syndrome, hypothyroidism, adrenal gland tumor, which requires treatment of primary disease. Hair loss caused by chemotherapy, after chemotherapy was discontinued three to six months will grow back.
Smoking and drinking, although not cause hair loss reasons, but also for hair growth and produce adverse whether the computer radiation will aggravate hair loss has not been scientifically proven, but an unhealthy lifestyle will definitely affect the growth of hair, and a regular life, nutrition a balanced diet will make the hair benefited.
