what does permanent hair color mean
Permanent color uses a developer (usually 10, 20, or 30 volume) to change the color fo your hair. This color is, as the name suggests, permanent. It will not wash out. Some people find that their hair will not hold permanent red hair color molecules. Usually this is caused by hair damage, but it could also be natural porosity issues. Permanent hair color is supposed to be called âhair colorâ, not âhair dyeâ. I donât know when it became the standard term, but a lot of salon professionals get really upset about it, so itâs best to use the correct term. Semi-Permanent. One of the terms you hear most when referring to crazy colors is âsemi-permanentâ.
