Want to know that it is best to wash your hair once in a few days, let's first talk about: shampoo your hair, what is it that washes?
Many people intuitively think that washing hair is washing hair, but it really isn't!

When washing hair, what needs to be cleaned more than hair is the scalp.
The scalp is part of the human body's skin, which produces oil, produces keratin, and is more likely to cause skin problems due to poor cleaning, followed by hair loss problems [1].
Therefore, when washing hair, if you just do it against the hair, you are likely to still feel itchy and dandruff after blow drying.
Because it is more important to "wash the scalp" when washing hair, the frequency of shampooing should be determined according to the situation of the scalp.
If the scalp is oily, a day without washing has been oiled to the end, then advise you to wash your hair every day, after all, even if others have no opinion... You should be very uncomfortable yourself!
If the scalp does not like to produce oil, two days without washing is still dry and fresh, then you can wash it every two days, or even wash it every three days.
In fact, the frequency of shampooing does not require rote memorization, whether it is oily scalp or dry scalp, as long as you follow the principle of "keeping the scalp clean and fresh".
Which is better about washing your hair frequently or not washing your hair often? The truth is this:
Washing your hair frequently will not cause hair loss
As long as there is no violent pulling during the shampooing process, the hair that falls down is the hair that has entered the rest period, and it is not a pot of hair loss at all
Moreover, the hair that enters the telogen phase is shed early by washing the hair, which is more conducive to the hair follicle entering the next growth cycle [2].
Not washing your hair for a long time is even less healthy
The accumulation of grease and skin in the scalp will make the microorganisms that feed on grease and horn grow and develop.
At worst, the scalp is satiated or smelly (caused by microbial breakdown of grease and dandruff), and the risk of infection and dermatitis is increased.
Once the scalp is infected and dermatitis, dandruff increases, hair follicles are blocked, and hair loss is naturally found [1].
Some people like to wash their hair in the morning and start the whole day refreshingly; some people like to wash their hair at night and clean it into the bed.
When is it best to wash your hair? As long as it is blown dry, it is good at any time.
After all, washing your hair in the morning without blowing drying out, encountering strong winds, catching a cold for a second;
At night, I lay down when I washed my hair wet, and when I woke up, I had a headache.
Don't blame Brother Dian for not reminding you when the time comes
After washing the hair, whether it is dried naturally or dried by the hair dryer is also a big problem.
Natural air drying is better for hair and minimal damage to hair texture.
But natural air drying is too time-consuming for Rapunzel, and the scalp is always wet and easier to catch a cold.
Therefore, hair dryer drying is still necessary~
First, I would like to share with you a few tips for blowing your hair:
1. Blow dry the scalp first, blow in the order of the root to the end of the hair, so that the drying speed is fast and it is not easy to catch a cold.
2. The hair dryer should be taken as far as possible, and the wind blown out should not burn the skin [3].
3. Blowing wind in the direction of the hair, can help the hair scales of the hair to close, so as to blow out smooth hair.
4. When the hair is semi-dry, you can switch the cold air to full dry, which further reduces the damage of the hair blowing to the hair.
Finally, 4 shampoo and hair care tips:
1. Comb through long hair before washing to protect hair and save time
2. Use conditioner for long hair, remember not to apply scalp
3. You can also use the shampoo comb to clean the scalp
4. Rinse the hair product more, leave no foam and no residue
Protect your hair!
After all, there really isn't much left!
