Best semi permanent hair dyes in 2023 tried and tested

Redken’s Shades EQ Demi Permanent Hair Colour Red Kicker is one of the best hair colour changers around and lasts for up to 28 washes. Called “demi-permanent” rather than “semi-permanent”, it’s ammonia-free and pH balanced for reliable, even colour without the harsh chemicals. The high-shine-giving liquid formula is perfect to gloss, refresh, tone and correct with no lift in as little as 20 minutes, making it ideal on days when you really need a quick refresh but don’t have much time.
