## Description

Say hello to natural-looking, feel-good dark brown hair colour. Designed by the world's leading hair colourist, Josh Wood, to cover greys without compromising the health of your hair. Formulated without ammonia or PPD, Josh Wood Colour hair dye is kind to hair and leaves it soft, shiny and with a natural colour finish. To cover grown-out roots, only apply permanent colour to the regrowth. Do not apply permanent colour over highlighted or balayage mid-lengths and ends, it will colour over and remove this effect from your hair.If you want all-over colour, apply permanent colour to your roots and mid-lengths, only colouring your ends for the last 10 minutes of development time for a freshly-coloured salon finish. Need advice on choosing a shade? Email a photo of your hair to expert@joshwoodcolour.com and our team of colourists will make a personalised recommendation just for you.

Review: Very good - Easy to use - my new hair dye either buy it from here or just my look depends who has it cheaper. I do like the black gloves it comes with too. Does cover the greys too
Review: Super Dye - I usually use a different brand this was a lot cheaper so wondered if it would be ok. It's really good and smells lovely. The gloves are proper salon gloves that actually fit and there is also a wipe if you get the dye on your skin. Will definitely buy it again.
