1. Don't wash your hair for three days after dyeing your hair.

I believe that many people will have such an experience, when they dye their hair, usually the stylist will tell everyone to keep their hair unwashed for three days, which is actually because the cuticle on the hair that has just been dyed is still in an open state.

If we wash our hair at this time, it will easily lead to fading, so if we don't wash our hair within three days, we can effectively integrate the hair dye with the hair, so if you want the hair color to last longer, you must remember this small advice.

But if you really can't stand it, you must pay attention to the water temperature when washing your hair, and wash your hair with water that is too hot, otherwise the color will fade more easily, and it will be in vain.

In fact, just after the hair, our hair is damaged to a certain extent, so if you use a hair dryer at this time.

and curling irons, which can easily cause more serious hair damage. Therefore, if you really want to use such a product, it is recommended to apply a hair mask on top first.

Then use it again, so that it will have a good protective effect on the hair.

In the scorching summer, many friends may only pay attention to their own sunscreen. And ignore the fact that the hair also needs to be protected because of ultraviolet rays.

It can easily break down hair dye. Therefore, if you expose your hair to the sun just after dyeing, it is easy to lose color, so we need to bring a hat or wear some hair care products with sunscreen at any time.
