Semi-permanent vs Permanent Hair Color
Which should you choose? If you are looking for a gentle boost to your hair color that does not give you regrowth then a semi-permanent color is for you. These colors, sometimes called glazing, color stains, or washes, work by coating the hair with a non-peroxide color that washes out over a 4-6 week period. They will cover most gray hair, and will actually help to tame any annoying frizzies you may have. Semi-permanent colors are the most gentle way to color your hair and are a low risk way to try out a new color. It is recommended that you use semi-permanent colors for as long as they are giving you the results you desire.
