If you have dark hair, you will only be able to achieve a dark blue colour without using bleach. If you have dry or coloured hair, it’s best to visit a hair salon in order to achieve a quality result. This type of dye won’t lighten coloured hair or damaged evenly, so you won’t be able to get a quality finish. Avoid using hair chalk or spray-in color, as this won’t show up on dark hair.
If your hair is really knotty, use a detangling spray to help loosen the knots. Make sure your hair is pretty clean and free of product before you dye it. If you haven’t washed your hair in the last 48 hours, it may be best to shampoo it with a small amount of shampoo, then dry it before you get started. However, don’t scrub your scalp, as you want to leave some of your natural oils in place to protect it from the chemicals.
Don’t worry too much if dye gets on your skin, as it will fade after a few washes. Never wear your favourite shirt when dyeing your hair, as the colour is nearly impossible to remove from fabric. Apply the dye in an area that is easy to clean, such as on tiles.
Mix the dye over the sink to avoid accidental spills. If a mixing bottle isn’t supplied in the box, mix the dye and the developer in a disposable bowl with a plastic spoon. If you have long hair, it may be easier to mix and apply your dye using a bowl and brush. Most packets will come with a brush. If there isn’t a brush provided, purchase one from a pharmacy or hair salon.
Start at the front of your head and slowly work your way to the back of your head. Also, be sure to wear gloves so the dye doesn’t get on your hands while you’re massaging it into your hair. If you’re using a brush, paint the dye onto your roots with a downward stroke and then slowly work your way down to the ends of your hair. Try to apply your dye as quickly as possible to create an even result. However, make sure you fully saturate your hair. When you are brushing the dye onto the hair at the back of your head, use a mirror to help you see or ask a friend to help you.
Avoid leaving the dye to soak for longer than the directed time, as it can damage your hair. Similarly, don’t rinse the dye out before the soaking time is up, as this can give your hair an uneven colour. Put a plastic shower cap over your hair to prevent the dye from dripping onto the floor. Set a timer to help you keep track of time.
Don’t worry if you notice blue dye going down the drain, as that is just the excess dye that hasn’t been absorbed into your hair. Avoid using hot water, as this can damage your hair.
The shampoo will also help re-balance your hair’s pH. Sulfate- and sodium-chloride free shampoos are good products to consider.
If your box of dye doesn’t have a sachet of conditioner, use a colour-safe conditioner instead.
If you don’t have any makeup remover, try using coconut oil instead. If you have a lot of dye on your skin, you can try applying shampoo over the dye before you wet your hair. This may help prevent the dye from staining your skin. Dye stains tend to fade over a couple of days.
