Normal Hair
If your hair is naturally lustrous and easy to manage, it falls in the category of normal hair. The oil glands are producing the amount of oil that your need for the health of the hair. The distribution and flow of oil along the hair shaft is normal, keeping the hair free of problems. This, however, does not mean that your hair does not require regular care. There are several factors that can upset the normal balance of the scalp, like exposure to the sun, air pollutants, permanent wave lotions, sprays, dyes, chemical colourants or illness. Therefore, normal hair must also be given regular care.

Dry Hair
If your hair is difficult to manage and has the 'flyaway' look, you probably have dry hair. The oil glands are not secreting enough natural  oil, or the hair has suffered damage from chemical  reatments and exposure to the elements. Dry hair looks dull and acquires split ends easily. It may also be brittle and break off easily. Sometimes, the use of wrong shampoos can cause dryness. So also can a bad case of dandruff.

Oily Hair
If you have an oily skin, the chances are that your hair is oily too. The sebaceous glands are over-active and are producing excessive oil. Your hair looks good when you shampoo, but becomes limp soon after.

Mixed Condition Hair
This kind of hair usually has poor distribution of oil along the hair shaft. The scalp may be oily, but the hair is dry. There may be dandruff, with the scales clogging the pores of the scalp.
