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.
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.
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 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 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 secret of how to treat, cure, prevent and avoid greasy hair is to treat it from both the outside, and the inside. For the outside: avoid brushing your hair too frequently, and when you brush avoid brushing your hair vigorously. When you wash your hair, the best shampoo for greasy hair is a mild-ph extra cleansing/clarifying shampoo that is formulated for greasy hair. Avoid moisturizing shampoos as they can leave some oil in your hair to protect against dryness. When washing your hair, avoid scrubbing your hair and scalp vigorously, lightly massage your hair and scalp instead.
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.
