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.
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.
Fluctuating hormones can cause greasy as hormones play a part in sebum production. Greasy hair is most common in women because of either pregnancy or monthly cycle, older women going through the menopause, and teenagers experiencing puberty. Stress can be a contributory factor in greasy hair as it is known to affect hormones levels. People with fine hair on their head may experience excessive greasy hair as they have more hair follicles and more sebaceous glands producing more sebum.
There are several external causes of greasy hair. Washing your hair too frequently can cause more sebum to be produced as frequent washing can strip the hair of oils, to combat this sebaceous glands excrete sebum. Sebaceous glands can be stimulated through vigorous scrubbing of the hair and scalp while washing. Touching your hair can also stimulate sebaceous glands, along with vigorous hair brushing which carries oil throughout the hair. The over-use of styling products can cause hair to look greasy as the products can build-up at the roots. Everyday environmental pollutants can also cause hair to look greasy.
There are also several internal causes to greasy hair as well. Along with changing hormone levels, a major cause of greasy hair is the food you put inside of you, i.e. you diet. Western diets are usually much greasier, containing more fat. They are usually processed, containing many additives, and typically are higher in fat and sugar. The high fat content of the diet increases oil in the skin which can lead to greasy hair. The meat in a Western diet often contains some hormones, and these hormones can add to the levels of unbalanced hormones. Greasy hair can also be a sign of a diet that is low in vitamin B.
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.
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.
