Why women do not go bald?

For starters, women also have baldness, although not as intense as common in men.

 The most common form of baldness is known by doctors as androgenetic alopecia and that says it all: baldness is motivated by genetic inheritance and by androgen hormones, which define male sexual characteristics.
 That is, although women also suffer from hair loss, the problem is determined by male hormones.

Understand why: the main biochemical reaction that generates baldness happens when the enzyme 5-alpha-redutásia acts on testosterone (the main type of male hormone), producing another hormone, dihydro-testosterone (DHT).
 This hormone is largely responsible for the thinning of the wires and the consequent fall, but he is not solely responsible.
 After all if one does not have cellular receptors sensitive to DHT in the scalp, the hormone does not act.
 And what defines the sensitivity of these receptors is genetic inheritance.
The difference is that women produce much less testosterone than men, and therefore, even if they have a genetic predisposition, are not sufficient to produce such devastation DHT in the hair - the most common is that the hair is thin, like a baby, and not come to fall. Another difference between the sexes is the position of the hair bulbs (where each hair leaves), and thus, baldness is also different. "In men, hair loss starts from the forehead region, with the famous entries, and the vertex (one point at the top of the head where the wires are). Among women, alopecia is more concentrated at the very top of the head"
