Washing your hair and soon after feeling that it has that dirty and oily look is really quite frustrating. That's why many people want to find out how to get rid of greasy hair quickly.
We can say that, in addition to correct hygiene, you should be aware of the causes of oiliness. In general, hair produces its own oils through the sebaceous glands — sebum, which is naturally formulated to moisturize the skin and hair.
Even when functioning normally, these glands can still experience some problems. When we wash our hair with shampoo, we are removing all traces of sebum there. Our body understands, then, that it needs to reinforce the production of this substance to replenish this natural grease and keep the scalp hydrated.
In addition, there are numerous other situations that can lead to uncontrolled oil production, such as hormonal issues or even seborrhoeic dermatitis, for example. In the case of hormones, adolescence, pregnancy or menstrual period can be the triggering factors for this situation.
However, it is more common that these situations affect people with straight hair rather than those with wavy hair, since the oil does not travel so easily through this kind of lock. That's why, often, hydration is more important for those with wavy and curly hair.
Clearly, other causes are also involved, such as:
bathwater at a very hot temperature;
the habit of combing or running your hands through your hair;
unbalanced diet and lack of certain nutrients;
excessive stress on a daily basis, which can stimulate the production of natural oils.
