How big is the harm of blow hair?
The harm of blowing hair with hair dryer is obvious. Many people are used to dry their hair with hair dryer after washing their hair at home, but if they don't use it properly, the water in their hair will be blown away. If the moisture content of hair is reduced to less than 10%, the hair will become rough and bifurcated, which is the result of frequent use of hair dryer. So what can I do after washing my hair?
1. Natural air drying or hair dryer drying
Is it better to air dry your hair after washing or blow dry it with a hair dryer? The answer is not completely correct. Hair dryer can accelerate evaporation, but overheated temperature can cause hair to become dry, lusterless, even bifurcated and broken. There must be some damage to hair when using hair dryer frequently. If the weather is warm and suitable for natural air drying, try not to use the hair dryer; if it's winter or there's an important date, and the hair is too much to dry, use the hair dryer. Compared with the damage of hair dryer, it's more uncomfortable to go out with wet hair, and it's not good for hair.
2. Hot air or cold air
Professional stylists will use hot air at the beginning and cold air at the last stage, because the main purpose of hot air is to dry hair, and cold air is more for modeling, we can also learn from this sequence. If you just want to dry your hair, there is no problem with the whole hot air. Some people are sensitive to the changes of cold and hot air. If you don't master it well, you may feel uncomfortable blowing. Finally, no matter what wind, it should be far away from the scalp. 15-20cm is necessary, otherwise it will stimulate the scalp greatly.
3. All or half
Blow dry the hair completely or blow it to 70-80% dry. It depends on the specific situation. If you plan to go out after blowing your hair, whether it's for blowing or natural drying, it's better to wait until the hair is completely dry before going out, so as to avoid headache caused by evaporation of water and heat, and the hair is also easy to get dirty; if you don't go out immediately, it's better to blow the hair to 70% or 80% dry, because the 'protective film' grease on the scalp has been removed during the shampoo process At this time, the water is also lost in a large amount, and the hair will certainly become dry, so that the hair will gradually air dry, which is equal to give the hair a certain buffer time and protection effect, not to crack instantly.
4. Use hair care essential oil
The main function is to apply it on the hair before blowing, insulate the hair and reduce the damage of the hair. It's simple but it works, and hair can be much smoother.
5. Pay attention to the direction of blowing hair
Blowing from the hair root to the hair tail is the best way to protect the hair, because you are blowing along the growth direction of the hair scales, and the hair will blow more and more smoothly; blowing from the hair tail to the top, blowing against the growth direction of the hair, the hair will become fluffy and shapeless, because at this time, the hair root will not be too close to the scalp under the action of the wind. Pay attention to blowing the hair roots first, then the hair ends, or let the hair ends dry naturally, so as to minimize the damage of the hair dryer.
In addition, it is better to keep moving the hair dryer, because when blowing an area, if the hair dryer is still, it is easy to damage the hair. Therefore, it is recommended to use both hands when blowing the hair, one hand to move the hair dryer away.
It's better not to blow back to wet the hair, because the hair scales are open. Blowing along the direction of hair growth will make the hair scales close. If you blow back, the hair scales will open, and the more you blow, the more fidgety.
