In the hustle of our everyday schedule we are left with very less or no time to take care of our hair. Also, the pollution level in the air makes the situation worse.

The human hair is made up of a tough protein called Keratin. Each strand is anchored by hair follicle into the skin and the base of the hair follicle is formed by the hair bulb. The blood vessels nourish the cells inside the hair bulb and also deliver hormones that play the major role in modification of hair growth and also structure at times.

Why does hair gets oily?

The glands in the skin produce an oily substance called the sebum. The sebum helps provide moisture to the hair and keeps it from drying out. The glands producing sebum are located next to the hair follicle. So, through the hair follicle the sebum channels out to the skin and then to the scalp. The amount of sebum production depends on every individual’s hormones.

What factors influence how often one should wash their hair?

Every individual has different factors which determines how often one need to wash their hair. Below mentioned are the key factors which helps one determine how often it is required for them to wash off their hair:

Oil

The major reason why one washes off their hair is excess of oil onto the scalp. Oil onto the scalp can leave the hair limp and clumpy. The amount of oil onto the scalp differs for every individual. The age group that is most affected by this is the teenagers and the adults till their 30’s. The content of sebum is higher in this age group. With age, the scalp eventually starts becoming dry.

Some people have very fragile and thin hair, so with every washing their hair tend to become weaker and gets damaged easily. These people might wash their hair every alternate week as well. On the other hand there are people who produce enough oil that they might need to wash it off on daily basis. However, the majority washes their hair every couple of days.

Hair Type

People who have straight and thin hair needs to wash them off frequently, while those who have curly or wavy hair can wash it at a longer interval. The straight hair gets easily coated by sebum, which tends to make the hair look greasy much faster. On the other hand the sebum doesn’t coat easily onto thick, curly or wavy hair, leaving the hair dry. As curly hair needs more moisture to stay soft and frizz free so sebum plays an important role to moisten them up and provide with beautiful and well defined curls.

Over washing of hair should be avoided especially with harsh shampoos as it can damage the hair and lead to major hair loss as well. The situation gets worse when the harsh shampoo gets combined with chemical treatments or hair styles which tug at the root.
