It is very much more likely a sign of someone who has looked after their hair with proper care and attention to detail. It is important to choose a shampoo and conditioner that is right for you, hair gets dirty when sebum, an oily substance secreted by the skins sebaceous glands, coats the shaft. Dead skin cells and air bourne dirt stick to the sebum. It goes without saying that a well-balanced diet is essential to healthy hair growth. Poor diet can be reflected in hair quality to quite an amazing degree, dandruff, dry hair and even hair loss can result.
Stress can also cause a problem in both hair loss and dandruff.
Both of which can be detrimental to a lovely shiny head of hair. The type of shampoo that you use is a purely personal choice, the cosmetic companies that produce them have spent millions of pounds on research over the years so you can usually be sure that the shampoo will clean your hair. Try to avoid using a shampoo that is very mild, like a baby shampoo as this will make your hair very flyaway. One of the best shampoo types to use is a shampoo with a balanced P.H. value. These shampoo's will return your hair to its natural P.H. level and make manageability very easy.
