Why do so many women stop taking care of their looks after getting married? While many people agree that hormonal changes can change body weight and looks still the way some women let themselves go after marriage involve more than weight gain. Some women stop doing their hair, wearing makeup or trying to look better. I am also sure you noticed how some celebrities never seem to gain weight or look bad even after giving birth. In other words, there seems to be something more than the "hormone changes" arguments going on. The word we are looking for her is motivation. Many women lose motivation to look good after getting married but the question is, why does this happen?
