How long to leave semi permanent hair dye in before rinsing

Hair dye is a trendy procedure. We like to dye our hair at home. Often it seems that this is a very simple process: it is enough to apply the dye, hold the right amount of time, wash off, and a new hairstyle is ready.

And for how long to leave hair dye in?

You should leave hair dye in for 30-45 minutes. Follow the instructions on the box. After 30 minutes, the ammonia and peroxide from hair dye go deeper into the hair structure and change its pigment.

The procedure lasts from 30 minutes to three hours, depending on the hair length, dyes type, and color. 

Of course, dying in itself is not particularly difficult, it requires only thoroughness, accuracy, and attentiveness.
