X chromosome, 母系遺傳, 要看舅舅的頭髮多寡才準.

一半一半....只是在女性該基因是隱性
所以如果你母親的兄弟有人禿頭,你父親也有禿頭
...那肯定是逃不掉了

跟家族男性有關!

EX: 外公,祖父,舅舅,叔叔,老爸 之中只要人有禿頭,你都很可能會中標

還要順便觀察鄰居老王的髮量.............

Key gene 'may reverse hair loss'

Bald mice re-grew fur once the gene was manipulated

Scientists believe manipulating genes within hair cells can reverse baldness.

An international research team has isolated a gene involved with hair growth, which may provide clues to the treatment of baldness.

The researchers isolated a gene that when faulty causes an inherited disorder called anhidrotic ectodermal dysplasia, which afflicts about 125,000 Americans, causing them to have little or no hair, missing teeth and poorly developed or missing sweat glands.

When the gene is normal, the researchers said, it apparently affects the hair follicles of men. The findings are being reported in the August issue of the journal Nature Genetics.

"The researchers don't know what it's doing yet, but there is a possibility that its activity is needed to keep hair," said Linda Sage, a spokeswoman for the Washington University School of Medicine in St. Louis, where much of the research was done.

"The gene clearly operates at an early stage of embryological development of the skin," Dr. David Schlessinger, director of Washington University's Center for Genetics in Medicine, said. He led one of the research groups in the study.

"We also speculate that it may be necessary throughout life for the continuing health of these skin organelles. So, naturally, we hope it holds the secret to hair growth," Dr. Schlessinger said.

The disorder, which does not affect women, is caused by a defective gene in the X chromosome.

女生也會遺傳到禿頭基因
但會變成隱性.....頭髮變少比較不明顯

基因是每個人都無法制的
所以一半一半

哀會這樣子問是因為我舅舅有禿頭但是有在吃柔沛
現在頭髮長出來滿多的
感覺上已經都沒有雄性禿的樣子~他吃柔沛吃的很成功
但是現在就很擔心我的小弟...總覺得他有頭髮變少的趨勢
就算吃藥變好...遺傳這種東西還是會"禍延子孫吧"

我覺得自己因素比較多
