All hair produces some oil to keep it nourished and healthy, as well as to protect the scalp. But too much oil production can lead to seborrheic dermatitis, a condition that causes red, scaly patches to form on the scalp, along with dandruff that is difficult to get rid of.
Having very oily hair can also make a person feel self-conscious and lower their self-esteem.
While some people may despair at their oily hair, there are several natural remedies they can try to help get rid of the grease without stripping the hair of its natural oils or irritating the scalp.
1. Wash more frequently

Washing too often or not often enough may cause oily hair.
Sometimes, oily hair is caused by excess oil that has not been removed properly. Some people with greasy hair may need to wash it every day.
Shampoo helps to get rid of excess oil. It will also remove excess hair products and any other debris that has built up on the scalp and causes the hair to look and feel greasy.
Flakes may become visible in the hair if a person does not use enough shampoo. This can cause dandruff and other scalp diseases.


2. Wash less frequently
Some people who do cleanse their hair once a day may be washing it too much. Washing too often can strip the hair of its natural oils, causing the hair to produce even more oil.
People who find their hair becomes greasy very quickly after washing it and have an itchy or irritated scalp might want to experiment with washing their hair less frequently. Doing so could help to balance out oil production and reduce greasiness.

3. Improve washing technique
It is easy for people to get into bad hair-washing habits that cause their hair to become oily and damage their scalp.
The correct way to wash the hair is to massage a small amount of shampoo into the roots and scalp.
Do this thoroughly but carefully, taking care not to scratch the scalp or hair. Scrubbing too aggressively could cause irritation and more oil production.
As most people find their hair is oiliest near the hairline, it is best to focus on washing the scalp and hair roots, rather than the ends of the hair. Rinsing the shampoo through the hair will be sufficient to clean the ends.
Rinse hair thoroughly to ensure that debris from the shampoo does not build up and weigh the hair down.
