Why do you feel grumpy in wet weather?

This is because there is more water in the air and the humidity has increased. Our hair will open the stratum corneum and absorb a lot of water, and the excess water will break the "hydrogen bond", leading to curling around the hair roots. In addition to moisture, the moisture in sweat will also lead to the imbalance of moisture in hair, making the original vertical and smooth hair become short-tempered and disobedient.

In addition, the scalp is easy to breed bacteria in an excessively humid state, which leads to scalp sensitivity. High temperature, sweat, hormone secretion and other factors will increase scalp pressure, leading to scalp tightness, itching and other symptoms. The dirt and bacteria brought by rain, if not cleaned up in time, will also destroy the normal growth environment of scalp, damage hair follicles and cause increased hair loss.

How to avoid short hair in wet weather;

1, wash your hair frequently

Many people think that hair becomes dry and short-tempered because of dampness, so it is necessary to reduce the number of shampoos, otherwise it will aggravate the loss of nutrients in hair. In fact, this view is wrong When the air humidity is high, wash your hair frequently.

Because if the scalp environment is too humid, it is easy to breed bacteria and make the scalp sensitive. So washing your hair often can keep your scalp healthy and your hair fluffy.

2, conditioner dosage

Usually we use less conditioner, because we are afraid of aggravating hair oil, but when it rains, we need conditioner protection more. The conditioner can lock the moisture in the hair and make it less irritable.

3. Dry as soon as possible after washing your hair.

When the hair is wet, the cuticle opens, and nutrients and water are easily lost. So blow dry your hair as soon as possible to avoid damaging it. However, it should be noted that the temperature should not be too high when using the hair dryer, otherwise it will stimulate the scalp, increase the secretion of scalp oil, and make the hair easy to get oil.
