Causes of greasy hair, and best products/shampoo for greasy hair

By Jennifer Summers

Greasy hair can look oily and dull, and have a lank and lifeless appearance. It can look flat and heavy, and it never seems to stay clean and fresh. It takes on a stringy appearance within a few hours of shampooing and refuses to stay full and fluffy. Does this describe your hair? Do you ask the question, why is my hair greasy? Greasy hair can cause social embarrassment as others may judge that the sufferer has poor hygiene and does not wash their hair frequently enough, even if they actually wash it every day.

Grease found in greasy hair is natural body oil called sebum. Sebum is produced by the sebaceous gland. Each hair has a sebaceous gland immediately under the skin. Greasy hair is healthy hair as the oil (sebum) is produced to stop each hair strand from drying and to stop the ends splitting. Sebum is produced by the body to lubricate hair and skin and prevents drying by providing a protective barrier. Sebum is your own built-in moisturizer for the body.

Greasy hair is actually an excess of sebum in hair which is a result of overactive sebaceous glands over-producing sebum, stimulated by hormones known as androgens. Although they are present in both men and women, androgens are male hormones and are higher in men. Androgens do two things: One, they increase the size of sebaceous glands in the skin. Two, they cause the sebaceous glands to increase the production of oil.

Because hormones play a role in the production of sebum, one of the causes of greasy hair is fluctuating hormone levels. Greasy hair is most commonly found in teenagers going through puberty, in women because of their monthly cycle or pregnancy, and older women going through the menopause. Stress is also known to affect hormone levels and can therefore be a contributory factor towards greasy hair. People with fine hair often find that they suffer from excessive greasiness, as they have more hair and follicles meaning there are more glands on the scalp, each producing sebum.

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 key of how to avoid, stop, treat and cure greasy hair is approach it from the outside and inside. Starting with the outside: avoid brushing your hair too often, and avoid brushing your hair vigorously. As you wash your hair, massage your hair and scalp lightly instead of scrubbing them vigorously. The beast shampoo for greasy hair is a mild-ph shampoo that is extra cleansing or clarifying. Look for a shampoo that is specially formulated for greasy hair. To protect against dryness moisturizing shampoos can leave oil in your hair, these should be avoided.

For the best results, the longer you leave the shampoo in, the better. If necessary, rinse your hair and shampoo again. The question of how often to wash your hair is as unique as the individual. The ideal frequency is 1-2 times per week, but to find your own balance start with washing everyday then reduce that to find a good balance of washing and oil production. If you use a hairdryer when styling your hair don't let it get too hot as heat will stimulate more oil production. When it comes to conditioning your hair, again use a conditioner designed for greasy hair. Apply conditioner to the mid and ends of your hair, but not the roots.

On the inside: with your diet, Reduce the number of foods you eat that contain white flour such as pasta, pastries and bread. Increase the amount of green and leafy vegetables in your diet, along with seeds, nuts, whole grains, salads, fresh fish and vegetables. Avoid sugar and foods containing sugar e.g. soft drinks, biscuits and cakes. Reduce the amount of fat in your diet, avoiding fried, greasy and fatty foods. Consider supplementing vitamin B in your diet. Reduce and eliminate as much stress as you can from your day to day life. - 15683
