Greasy hair never seems to stay fresh and clean, and can look heavy and flat. Within a few hours of shampooing it refuses to stay full and light and it takes on a stringy appearance. Along with looking oily, greasy hair can appear lifeless, lank and dull. Does this sound familiar to you? Do you ask yourself “why is my hair greasy?” Even if they wash it everyday, others can judge that the sufferer does not wash their hair frequently and doesn’t have good hygiene. This can cause much social embarrassment.
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 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 a more thorough cleanse, leave the shampoo in for about 5 minutes. You can always rinse your hair and shampoo a second time. How often you need to wash your hair is down to you. Ideally you should wash your hair 1-2 times per week. To find what is right for you, begin washing daily and then reduce the frequency to find your ideal balance of oil production and washing. If you plan to use a conditioner on your hair, apply the conditioner to the mid and ends of you hair only, and be sure to use a conditioner made for greasy hair. If you are using a hairdryer for hair styling don’t let the dryer get too hot, heat can cause the production of more oil.
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.
