The going bald soon be reversed after scientists discover why hair growth stand in life & # 39; after

Can & # 39; a long-loss & # 39; age-related hair, scientists declared at the back & # 39; new medical breakthrough.

The researchers believe they have discovered how to reverse the process by bringing gradually go bald hair b & # 39; success on the injured skin.

Scientists in School & # 39; New York Medicine activated pathway in the brain called sonic hedgehog.

This pathway is very active while babies are in the womb and hair follicles are formed, but is in the hair or injured & # 39 ;.

The figures suggest that about a quarter & # 39; the men start to go bald by the time they turn 25, starting with Prince William runs thin with only 22.

Women can also suffer with & # 39; 40 percent women suffer a loss of & # 39; visible hair at the time they are 40, according to the American Academy of Dermatology.

The study examined the damaged skin of laboratory mice, focusing on cells called fibroblasts to exacerbate collagen.

Collagen is a protein mainly responsible for maintaining the shape and health of the skin and hair.

The researchers also focused on fibroblasts because the cells have been known to help direct some of the biological processes involved in healing.

The team, led by Dr. Mayumi Ito, activate the signaling pathway of sonic signal octopus, which is used by cells to communicate with & # 39; other.

By spurred communication between these cells, the hair regrowth was observed within four & # 39; weeks in mice.

The hair root and shaft structures began to appear after nine & # 39; weeks, according to evidence published in the journal Nature Communications.

Scientists until now assume c scars and collagen accumulation in the damaged skin were behind its inability to get & # 39; connecting hair. But this evidence throws new light.

S & # 39; are the causes of hair loss?

The hair loss is common, b & # 39; about 25 percent of men begin to bald by the time they turn 25, according to The American Hair Loss Association.

Estimation & # 39; eight million women in the UK are currently suffering from a certain loss of & # 39; hair, according to a study & # 39; 2,000 women by cosmetics giant L & # 39; Oréal.

The most common type of & # 39; & # 39 loss; hair can & # 39; is activated by changing life events such as moving home, death or pregnancy, leading to an overall reduction in hair.

The tablet & # 39; Yo-yo, the contraceptive pill, the stress, eating disorders, drug chemicals in the water and modern pesticides in food were also associated with & # 39; loss & # 39; hair.

With most of these, the loss of & # 39; hair is temporary and can & # 39; be helped.

The nutritionists can say that if nutrient levels are low, it will be expressed by the hair. The hair follicles that have their roots in the scalp should be surrounded by a rich supply & # 39; blood to ensure that they are undernourished.

The dermatologists suggest that faddy diets usually result in iron deficiency, as can & # 39; avoid red meat. The vegetarians or vegans who are low in vitamin B12 and zinc may be susceptible to loss of & # 39; hair.

Research shows that the hair cut is linked to & # 39; progestogen – the synthetic form of progesterone found in Therapy & # 39; Pill and Hormone Replacement.

Dr. Ito said: "Now we know that this is a matter & # 39; signaling in cells that are very active as we develop in the womb, but lower in mature skin cells as we age

"Our results show stimulating fibroblasts using sonic path & # 39; & # 39 Hedgehog can, cause not before hair growth in wound healing."

Cutting & # 39; hair on the skin is damaged unmet need in medicine, said Dr. Ito, because the eviction of thousands suffered from trauma, burns and other injuries.

Not only is this breakthrough for skin injured, but the evidence is promising to improve hair growth in mature skin, it added.

Can & # 39; help in the search for better drugs to get & # 39; aging the hair growth.

Other experiments that turned the sonic hedgehog pathway revealed a higher risk of & # 39; tumors.

To avoid these risks, the team only turn fibroblasts located just below the skin surface where the roots of the hair follicle (dermal papillae) appear first.

B & # 39; of & # 39; successful results, Dr. Ito said this suggests that this obstacle could & # 39; was defeated, bringing science closer to the true skin rejuvenation after the injury.

The aim of doctors is to identify likely targets drug for hair breastfeeding. Currently, licensed drugs can & # 39; have adverse side effects.

Minoxidil, hand cleaner over-the-counter on foam or lotion, works by increasing blood flow to the scalp, clean the hair follicles.

Helps about two-thirds of patients, men and women – but can & # 39; have side effects ranging from rapid heart beat so swollen feet and stomach pain.

Finasteride, is only available with a private prescription for men. It works by blocking an enzyme that converts testosterone into & # 39; dihydrotestosterone (DHT), another form of & # 39; hormone which triggers kalzja.

Research shows that finasteride lead to some hair growth to 80 percent & # 39; men, but one in 60 experience impotence – and the risks increase the longer you're on medicine.
