Although hair has often been compared to \"3,000 strands\", but only with sparse hairs on the head, but it also is very troubling. In the eyes of parents, their little baby any physical characteristics, manners are the matter of great concern, especially looking at small baby that slick watermelon skin, a pinch or looks East and West a clump, some parts not long hair or dilute sparse drain pan for a few small head of hair, so MOM and dad are brooding.
Formation of hair
For hair problems, first of all to understand the formation of hair. Mackay Memorial Hospital Pediatric genetic Department Director Lin Xuanpei said that hair is produced by the hair follicle, and important member of the hair follicle and skin tissue, closely related to the formation of the skin. Embryonic development of the hair follicles of the initial matrix to three months in the epithelial layer, just start I saw in the eyelid, eyebrow, Chin and nose and other parts of the Department, after which only began to appear in the back, abdomen, and limbs. At the same time increasingly becoming of more mature follicle matrix and the cyclical growth phenomenon. Hair follicle cells are buried in the dermis, and begin to form soft hair, sebaceous glands, vertical muscle and vascular bundles are attached, and form a more complete hair structure, hair began to appear at this time of course.
The embryos before the seven-month-old, the whole part of scalp hair, except for head, all in a fast growing, relative position, behind the head hair in a State of slow growth.
Baby hair growth process
Newborn development stage after lanugo hair, soft hairs, and finally evolved into a permanent, time varying speed. In General, the fetus in the womb when the 4-month-old will make lanugo. After birth at term, every newborn has experienced at least once (rear) and two (Central Department) natural shedding of hair, and a new longer hair. Semi-after the age of hair growth into another phase, is a process of making bodiless lacquerware for hair, long permanent hair, started the stability of the hair growth cycle. Some of the babies in the womb, lanugo will gradually fall off; if lanugo less shedding, hair appears more infants at birth.
Baby hair growth, usually from the stop start his forehead, the regional difference in hair growth, it often feels sparse sparse sparse. Folk customs are rumors, born in early childhood full of hair and eyebrows shaved off in full when a month pushes the hair follicle stimulation, will grow thick and dense, in fact, this concept is not quite right. 2 to 3 months of birth, hair growth are still in slow stages, parents do not need too much tension. Usually about half a year after the birth, growth of hair will gradually be; if more than one year but the hair does not have signs of growth, you need to ask the doctor.
Color shades
Shades of hair and is closely related to genetic. With Oriental people, hair color is black, baby after birth as it has entered the permanent hair, hair color should appear black, but there are a few lighter than the baby\'s hair is dark brown or brownish-black, mostly normal. If some hair rendering hair status, perhaps because some hair follicles renders the aging stage, there is no right. But if a chunk of hair rendering a large number of white State, it may be affected by the disease.
Closing remarks
After the above describes the formation of hair, I believe that parents are to their baby\'s hair at the top there is a deeper level of understanding. Against hair loss, baldness causes and also to further grasp, if children encounter a similar situation, should be facing, reducing even more worrying, etiology of assisting children to seek, receive appropriate advice and treatment.
