The medical term for oily hair is Seborrhoe.
At the base of each hair shaft are sebaceous glands which produce sebum - the fatty oil in oily hair. The sebum allows the hair to slide through the scalp and protects the hair from the elements. If you have oily hair (oily scalp) the sebaceous glands produce too much sebum.

"Intense heat and humidity and hormonal changes (stress, birth control pills) can also accelerate oil production. Androgen, a male hormone, can activate the sebaceous glands. Stress boosts

What to do about it?
You should buy products containing ingredients like the tenside "Sodium Lauryl Sulfate" or "sulfosuccinate" - those cosmetic detergents create foam and bubbles and are great for removing oil from hair.
Shampoos for oily or greasy hair can also contain several herbs like resemary, chamomile, nettle or seaweed.
Many people think that their hair will become even more oily if they wash their hair a lot. The opposite is true: the most important thing you can do is to shampoo your hair daily with shampoos that contain gentle cleansing agents. Massage the shampoo on your hair and scalp so the sebaceous glands will loose their oil. It is important to massage not just your hair but especially your scalp.
Afterwards leave the shampoo on your head for at least three minutes in order to let the tensides do their work before rinsing the hair thoroughly.
Don't use shampoo for oily hair more than two or three times a week. it could cause itching and redness on your scalp. If you want to wash your hair daily you can use a mild shampoo the rest of of the days of the week. Don't use a shampoo with conditioning agents (also two-in-ones).
If your hair is only oily at the roots we advice you to wash it with a special shampoo for greasy hair. But don't use too much shampoo. Use the shampoo only at the roots. The hair ends will be washed too while rinsing your hair.
