Temporary
Strands in shades of gray and pastels have been lighting up our social media feeds recently. While these on-trend hair colours certainly make for pretty pictures, not everyone is ready to keep such a bold look for the long term. This is where temporary hair colours comes into play. Temporary hair dye, otherwise known as wash out hair color, coats only the outside of the hair shaft, so the results don’t last. This means that when you go to shampoo your hair next, the new color will wash out and your hair will return to its natural shade, allowing you to experience a new hair color without a major commitment. However, you should know that damaged hair that’s dyed with temporary hair color can appear stained after continued use over time.
Semi permanent
Semi-permanent hair color is ammonia-free, so its molecules get under the outer cuticle of the hair shaft but, unlike permanent dye, doesn’t penetrate the strand. Instead, they wrap around the hair’s cuticle, creating a coating of color that’s gradually washed away. Think of semi-permanent hair color as a lip stain. You know it will gradually wear off and you’re free to try another shade. So how long does demi-permanent hair color last? Approximately 24 shampoos.
