Buried beneath the surface of the skin hair grows out of tiny pockets cells. The sebum, is the natural oil is produce my sebaceous glands beneath the epidermis. The sebum helps to keep the hair lustrous, supple and resilient.
The production of sebum varies considerably from person to person. It is influenced by a variety of factors such as endocrine gland activity, good blood circulation and nerves and tension.

What causes "dry" dandruff? "Dry" dandruff is less serious than "wet" dandruff. According to researchers, due to insufficient production of sebum, there is sluggish circulation of blood making the scalp too dry. The symptoms are itching and the formation of small, white scales attached in masses to scalp or scattered loosely in the hair. They fall onto the back and shoulders when it flakes. It isn't likely to spread elsewhere and infection is rare. Other factors believed to worsen the situation are poor diet, lack of sleep and general uncleanliness. To relieve an overly dry scalp, an oil treatment is necessary. According to experts when the scalp is itchy:
- Use a cotton ball, rub the oil unto the scalp one section at a time. To stimulate circulation, massage with your fingertips, Wrap your head in a towel and leave the oil on for several hours. Afterward, rinse with hot water. To remove the oil, two rinsing will be necessary.
Wet dandruff is the bigger problem. It is caused by over-production of the sebaceous glands. It is characterized by the fast secretion and discharge of sebum, resulting in the formation of greasy scales. Infection is common, it can spread to other body parts with hair. According to hair experts the length of time it takes to control it depends on how long the condition has existed. One important thing to consider is age. Young people can shake it more easily than older ones because of body resistance. Home remedies for "wet" dandruff:
- Use of mild shampoo is recommended, preferably an organic one.
- Wash frequently to keep the itching under control.
- Massage with brush. Massaging with brush while shampooing is also helpful. The bristles get under the scalp to stimulate and cleanse it.

Control of the scalp's function is possible but it's impossible to clear them up permanently with dandruff. Even after finding a product that works, you must be willing to switch if the skin becomes oversensitive. Try alternating between a regular shampoo and dandruff shampoo. Frequent shampooing however is not a good idea. It dries the scalp more. Hair spray and hairdryers can be irritating. Hair sprays clogs the scalp and hair dryers dries it.

- Sometimes, the sudden oiliness has been caused by the hair products you are using. Avoid moisturizing shampoos and heavy conditioners which can leave thick residue on hair and making it look oily.
- Use a dandruff shampoo that contains zinc or salicylic acid, once or twice a week. These ingredients will strip product of residue from the hair shaft and inhibit oil production in the scalp.
- Always shampoo and rinse your hair in cool water. It adds body to your hair and is gentler than hot water says a hair expert. Spent at least a minute, deeply massaging your scalp. This cleanses away sebum and dead skin flakes while stimulating your hair follicles.
