Hair is a very important expression of who we are. It is often the first thing you notice when you meet someone, especially if they have nice hair. Well-groomed, luxuriant, lustrous, hair is, quite simply, beautiful and sexy. It can signify youth, health, strength and vitality. Many people don't feel right unless their hair looks perfect. If their hair looks good they feel great. Otherwise they say they are having a 'bad hair day'. This applies to men and well as women.
