Semi-permanent hair dye typically lasts between 4 to 12 washes, which generally translates to about 2 to 6 weeks depending on hair type, the specific product used, and how often you wash your hair
. Most commonly, you can expect the color to last around 6-8 washes or roughly a few weeks before it starts to fade noticeably
. The longevity of semi-permanent dye depends on factors such as:
- Hair porosity: More porous hair tends to hold color longer, sometimes up to 15 shampoos with certain products
- Hair care routine: Washing with cool water and using dry shampoo can help extend the life of the color
- Original hair color: Lighter hair may retain color longer, while darker hair might see faster fading
- Product formula: Different brands and formulas vary, with some lasting only 3-6 washes and others up to 12 washes or more
Semi-permanent dyes deposit color on the hair surface without altering the hair structure permanently, so the color fades gradually without damage and can be refreshed or changed easily
. In summary, semi-permanent hair dye lasts about 4 to 12 washes or roughly 2 to 6 weeks, with some high-quality products lasting up to 15 washes depending on hair condition and care
