Temporary Hair Colour
Temporary, or semi-permanent, hair colours penetrate your hairs’ outer cuticle to gain access to the hair’s cortex. They last for about six weeks and tend to fade progressively. As temporary colours don’t contain bleach they cannot lighten your natural shade.
Benefits of Temporary Colours
Semi-permanent colours give you a more natural colour than wash-out or 'veg' colour dyes, and are also easier to use. You can use semi-permanent dyes straight from the applicator as they don’t have to be pre-mixed. Additionally, as temporary colours are not permanent, they will eventually wash out if you are unhappy with the colour.
Disadvantages of Temporary Colours
Colour fade: Temporary dyes fade with shampooing and exposure to air. This means they need to be frequently reapplied, which can be damaging.
Overlapping: Due to frequent overlapping, temporary dyes can leave you with darker ends and lighter roots. The reverse should be true with hair colour.
