How do I use the toning shampoo, and what safety precautions should I take?

Using the Wine Red V48 is simple, but because it's a colourant, a few steps matter.

How to use: Wet your hair thoroughly, apply a generous amount of the shampoo, and massage it into a lather. Leave it on for a few minutes so the colour pigments can coat the hair – the exact time isn't specified in the product description, so follow the instructions on the label. Then rinse thoroughly until the water runs clear. You can follow with a conditioner if you like, though the product already contains aloe vera to help keep hair smooth.

Safety precautions:

• Always do a 48-hour patch test before first use, even if you've coloured your hair before – sensitivities can develop over time.
• Avoid using it on eyebrows or eyelashes.
• If you have previously reacted to hair dye products, be especially careful.
• This product is ammonia-free, so it's less harsh than permanent colouring, but it's still a cosmetic colourant.

If you have a chronic skin condition, are pregnant or breastfeeding, or are on medication, consult a specialist before use. Also, note that this shampoo only adds tone – it does not lighten or bleach your hair.
