Semi-permanent hair colour is a non-permanent dye that coats the outer layer of the hair shaft without deeply penetrating it. Unlike permanent hair dye, it does not contain ammonia or peroxide, making it a gentler option for those looking to experiment with colour without causing long-term damage. This type of hair colour gradually fades over time, typically lasting between 4 to 12 washes, depending on hair porosity, colour intensity, and washing frequency.
One of the biggest advantages of semi-permanent dye is its ability to enhance natural hair tones, add shine, and temporarily cover greys. It works particularly well on pre-lightened or naturally light hair, as it does not have the ability to lift or lighten the existing hair colour. Semi-permanent colours come in a wide range of shades, from subtle natural tones like browns and reds to bold and vibrant hues such as pink, purple, and blue.
Application is simple and does not require a developer. The colour is typically applied directly to clean, damp hair and left on for a certain period before rinsing out. Since it fades gradually, maintenance involves periodic touch-ups or using colour-refreshing shampoos and conditioners.
This type of dye is perfect for those who enjoy changing their hair colour frequently or want a temporary change without the commitment of permanent dye. It is also a great choice for individuals with dry or damaged hair, as it does not contain harsh chemicals that can further weaken the hair. Semi-permanent hair colour allows for creative expression while keeping hair healthier and more vibrant.
