Hair thin out some people from the age of twenty or thirty, forty or fifty years old bald, called little bald. If you think bald mature and a scholar of at most a few minutes when I was young, so I am pleased to tell you that little bald is hereditary, and the boy is autosomal, girls for recessive. That is, genetic boys will definitely be symptoms, genetic girl symptom does not occur. Both parents with less bald the genetic gene will be passed on to children on an equal footing, but symptoms appear absolutely different. Broadly speaking, less bald is the father to their son.
If the father is bald, grandfather was bald, the incidence of little boy of about 100%. However, if the father is not bald, whose children would be what? This depends on the grandfather, grandfather less bald, child 25% may, if the grandfather a concentrated, that kids can say that basically do not have to worry about.
Than less bald, a young person with greying hair, a young person with greying hair and genetic has a great relationship. If the father is a young person with greying hair, their children, is a high possibility of a young person with greying hair. Because the root causes of the formation of white hair is hair melanin that is generated as a result of too little, and the amount of pigment and the environment, diet, metabolism, and so has to do, so it\'s hard to say exactly how many genetic probability. If happens, fear nor use without much obstacle, kids don\'t care too much, dietary diversification, keeping open mind on the line.
