So not too long ago I did my normal dye of black, and decided to switch it up to the Herbal Essences brand of dye, in the color black. I applied as normal, and I got a little freaked when it felt like my scalp itched a bit. Like bugs crawling over my scalp. I washed it out of my hair later as normal, and noted no redness or other signs of reaction.
The time has come to do another dye session and now I'm a little worried. I know I should do the patch test, but doesn't the dye lose effectiveness if mixed ahead of time and used over 24 hours later?
