For best results, particularly with lighter shades, apply to hair that has been pre-lightened to pale blond. Apply to freshly washed (not conditioned), dry or damp hair. Apply using latex gloves. We recommend using a tinting brush to ensure even coverage. Work the dye into the hair for a few minutes and leave for at least 15 minutes (you may leave this dye on for longer as long as you cover your hair with plastic wrap or a shower cap to prevent it drying out). Rinse with warm water until the water runs clear.
For longer lasting colour, use a shampoo and conditioner for coloured hair.
Although these dyes do not contain the harsh chemicals of other dyes such as ammonia and peroxide, there is still a small chance that they could cause an allergic reaction. For this reason it is imperative that you do a strand and sensitivity test before using them. An ingredients list is available above and can also be found on the product’s packaging (ingredients list can sometimes be found under our sticker). NEVER use any of these products on eyelashes or eyebrows.
As you would expect from a dye these colours can stain textiles, ceramic, wood and other surfaces as well as temporarily stain skin and nails so be careful to cover surfaces and wear gloves when applying the colour. Once used these products may also rub off your hair and skin and onto clothing and bedding. Although this usually disappears after washing it’s worth bearing this in mind. Staining to bathtubs, basins and showers can easily be cleaned using a bleach based cleaning product.
Do not mix with peroxide.
Colours may cause permanent staining to bleached or chemically treated hair. Tip: You can avoid staining on your skin by applying a layer of vaseline anywhere on your skin where dye may come in contact.
