How often should you wash your hair?

When summer comes around like it is now, our bodies are

affected a great deal by temperature, humidity, and ultraviolet rays.

Especially when the stifling heat becomes intense, it is common

to sweat profusely as if it were raining, even without any special

movement.

This is something we have to deal with until the season passes,

and when we look at a body covered in sweat and all kinds of secretions,

it can feel unpleasant and somehow off-putting, so we end up being

even more thorough with face washing and showers than at other times.

And the shampooing that is part of our daily routine is also done diligently,

whether in the morning or evening.

We go through this process as a regular habit and naturally do not question it,

but did you know that the number of times you wash your hair can vary

depending on each person’s scalp type?

While some people have abundant hair that grows normally,

others may feel that the amount of hair falling out is much greater

than before even when they shampoo gently without strong stimulation,

using a comb or softly touching their natural hair with their fingers,

and when they notice that the areas where hair has fallen out look especially sparse

and empty, they may become worried that the things they did without thinking

have led to hair loss. It is understandable to be concerned,

but if you reduce how often you wash your hair out of fear that more natural hair

will fall out, buildup of waste and impurities can instead become an indirect

cause of worsening hair loss. So even if you have a condition that causes

natural hair to fall out, it is best to wash at least once a day if possible.

And if your scalp is of the dry type, washing your hair several times a day

would be like pouring oil on a fire.

To maintain healthy hair, an appropriate amount of sebum is necessary,

but if too little sebum is secreted, the skin and natural hair can become dry.

When that happens, the surface of the scalp may crack, and the hair may become

rough and brittle, making it easy to break or become damaged even from slight

impact or irritation.

For dry scalps, on days when there are no special circumstances such as exercising

or getting dust and impurities on the hair, washing once a day in the evening

is considered sufficient. In addition, after shampooing, it is important to dry

the hair completely, and finishing by supplying a suitable amount of oil with

products such as hair ampoules or essences can be helpful.

Oily scalps, which produce more sebum than dry scalps, may look oily again on

the natural hair by evening even if shampoo was used in the morning.

For this type, it is said to be good to divide washing into morning and evening.

If sebum is excessively secreted, it can clog pores, and once they are blocked,

it may cause inflammation in the hair follicles or skin.

So if you tend to be very oily, shampooing every day can be a way to maintain

healthy natural hair.

And if you always use gel or wax to keep a carefully styled hairstyle stable

and in place, regardless of your type, you should maintain a daily hair-washing

routine.

These styling products can cause considerable irritation to the hair and skin,

so if you go to sleep without washing away wax or gel, it can act as a cause

not only of scalp inflammation but also of unnecessary hair loss.

If you used them, be sure to wash thoroughly before bed so that no residue remains.

Above all, the number of times you wash your hair is important, but it is also

key to properly understand and follow the correct way to shampoo.

First of all, it is important to choose and use a product suited to your skin type.

Before starting, take a minute or two to brush your hair thoroughly, which can

remove waste and foreign substances stuck to the hair and help prevent tangles.

Even if the weather is cold, using hot water is not advisable.

It can cause minor burns to the skin and also affect the hair, so lukewarm water

at a moderate temperature is recommended.

Also, some people deliberately use their nails and scratch their skin as if to

feel refreshed while washing, but this should be avoided as much as possible

for the health of the skin.

Keeping up habits that need correction for a long time can also become a cause

of hair loss, so you should use your fingers—not your nails—to massage gently.

It is also good to rinse several times so that no residue of cleanser remains on

the skin or hair, and you should be careful not to comb wet hair immediately.

In this state, the hair roots are weakened, so the hair can fall out easily.

When drying, avoid hot air, which can damage the fibrous structure of the hair

and cause breakage or hair loss, and it is important to completely dry the skin

and hair with warm air.

If you leave the hair damp and wet without drying it properly and go to sleep,

it is like creating an environment where bacteria can thrive, so it can cause

skin inflammation. Based on the methods shared here, let’s pay attention to

scalp and hair care and keep them healthy consistently.
