Just dyed hair when washing attention to three points not easy to lose colour: one is the best time to wash 72 hours after the dye, to give the dye full colour time to keep it stable and lasting; two is to wash the water temperature of about 40 degrees, do not use more than 60 degrees of water wash hair; three is not to use the hair dryer after washing, can be wrapped in a towel and then coated with conditioner, wait for it to dry naturally.Point 1; wash your hair at a good time. You can't wash your hair immediately after dyeing, because you will clean your hair after dyeing in the barber shop, after that you should not be too eager to wash your hair, you can wait 72 hours and then wash your hair every 2-3 days, because very frequent washing will lead to pigment fading and colour loss.Point 2: The water temperature should be controlled. Whether it is summer or winter, do not use too cold or too hot water, summer can use about 30 degrees of water, winter with about 40 degrees of water, if the use of water is very cool or too hot, will let the hair scales shrink or expand, the pigment will be easy to lose colour will lose colour obviously.Point 3: After washing care is critical. After washing your hair as much as possible without a hair dryer, use a towel to dry and then wrap, apply some hair care to protect the hair, after washing and then wrapped in a towel to let it dry naturally, so that the best effect on hair care, and the colour of dyed hair can also be maintained better.
