Hair Dyes
Semi-permanent, neon and UV hair dyes
This category includes vibrant semi-permanent hair colours in yellow, green, pink, red, orange, peach, purple and silver, along with selected neon or UV-reactive shades and a hair-highlights item. Each product has its own quantity, formula and directions, so application and results should not be assumed to be identical across every colour.
Types and shades
- Semi-permanent hair dyes: bold colours whose longevity varies by product, hair base and washing frequency
- Neon colours: bright shades for a more striking visual result
- UV-reactive shades: products described by the manufacturer as reacting under suitable ultraviolet light
- Hair highlights: individual decorative hair pieces rather than a full hair-colour treatment
What affects the final result
The same shade can look different depending on natural or previously coloured hair, porosity and any prior lightening. Do not assume from a product image that bleaching is or is not required. Read the directions for the specific dye, check how much product is recommended for your hair length and confirm that it is intended for your starting colour.
Patch testing and application
Follow the manufacturer's warnings exactly, wear gloves and complete the required allergy alert test and a strand test before full application. Do not use hair colour on an irritated scalp, eyebrows or eyelashes unless the label expressly allows it. Protect clothing and surfaces, observe the stated processing time and rinse as directed.
