2019年8月12日 就職・転職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.https://www.yneed.co.uk
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 excess of sebum in the hair and comes as a result of an over production of sebum (oil) from over active sebaceous glands, stimulated by hormones called androgens. Androgens are male hormones that are present in both men and women, but are higher in men. Androgens do two things: First, they enlarge the sebaceous glands in the skin. Second, they cause these glands to increase oil production.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.
