Greasy hair can appear stringy and fail to keep its lightness and volume within a few hours of shampooing. Greasy hair can seem lifeless, dull oily and lank. It can also appear heavy and flat, refusing to stay clean and fresh. Is this describing your hair? Ever ask yourself "why is my hair greasy?" Others may judge people with greasy hair as having poor hygiene and that they do not wash their hair very often, even if the sufferer washes it every day.
The grease found in hair is called sebum and is oil that is produced natural by the body. Each of the hairs on your head has a gland called the sebaceous gland immediately under the skin, this gland produces sebum. Oil in greasy hair protects each strand form split ends and dryness, and is in fact a sign of healthy hair. Sebum is made as lubrication for the skin and hair, providing a protective barrier and preventing drying. Sebum is the body's own natural moisturizer.
Hormones called androgens can cause greasy hair by stimulating sebaceous glands, causing them to become over active and begin over producing sebum leading to an excess of sebum in the hair. Androgens are male hormones, and although they are present in both men and women, they are higher in men. Androgens make two things happen: First, they enlarge sebaceous glands. Second, they cause the increase of oil production from the sebaceous glands.
As hormones have a role in sebum production, fluctuating hormone levels can be one of the causes of greasy hair. Greasy hair can most commonly be found in older women experiencing the menopause, teenagers in puberty, and women in general because of their monthly cycle or pregnancy. Stress can also be a cause of greasy hair as it can affect hormone levels. People who have fine hair can sometimes suffer form greasy hair because they have more hair follicles and more hair follicles means more sebum producing glands on the scalp.
There are many external causes of greasy hair. Over washing your hair can cause increase sebum production as frequent washing can strip the hair and scalp of all oils causing the sebaceous glands to excrete more to combat this. A build-up of grease can occur due to washing your hair too often. Scrubbing your hair and scalp vigorously while washing you hair can stimulate hair grease. Touching your hair can also increase the glands to over-stimulate, as can vigorous brushing which can carry the oil throughout your hair. Environmental factors such as everyday pollutants can cause hair to look greasy, as can the over use of hair styling products as the products build-up at the roots.
There are also many internal causes of greasy too. I have already mentioned fluctuating hormone levels, but one of the main culprits when it comes to internal causes of greasy hair is diet. Western diets that tend to be greasy, high in fat and sugar, processed and containing additives which can be a major cause of greasy hair as the high fat content increases oil levels in and on the skin. Hormones can be found in meat in the western, adding to the unbalanced hormone levels. A diet lacking in vitamin B can also contribute towards greasy hair.
The best way of avoiding, preventing, treating and getting rid of greasy hair is to treat it from the outside and the inside. On the outside: steer clear of brushing your hair too frequently, and too vigorously. Avoid using a moisturizing shampoo as this can leave some oil in the hair. An extra cleansing or clarifying shampoo that has a mild-ph is the best shampoo to use for greasy hair. When shampooing, massage you hair and scalp lightly and do not scrub your hair and scalp.
When shampooing, leave the shampoo in your hair for approximately 5 minutes for a better clean. Rinse and shampoo again if necessary. It's up to you as to how often you should wash your hair. Once or twice a week is the ideal but to find your own balance of washing and oil production start with washing once a day, reducing how often you wash as you find that balance. If you are going to condition your hair, use a conditioner designed especially for greasy hair, and apply the conditioner not to the roots but to the mid and ends of your hair. If you use a hair dryer to style your hair, heat will stimulate oil production, so don't let it get too hot.
For the inside: do everything you can to reduce any stress that you may have in your life. For your diet, reduce the amount of fat and dairy products, and avoid fried, fatty and greasy foods as much as possible. Consider vitamin B supplements in your diet. Avoid sugar and sugary foods like cakes, biscuits and soft drinks. Reduce the foods containing white flour like bread, pasta and pastries. Be sure to eat lots of nuts, seeds and whole grains, and leafy & green vegetables, salads and fresh fish.
