Key benefits:

• Gives glossy, natural-looking colour and increased volume (maximise leave-in time for deeper shade)
• Conditions and strengthens hair, leaving a healthy shine
• 100% certified organic indigo, fairly traded and chemical-free

Indigo Black works by semi-transparently coating your hair shaft; the final shade depends on your existing hair colour and porosity. It may darken brown hair to a darker brown or black; lighter or grey hair must first be coloured red or brown before applying Indigo Black, otherwise an unattractive bluish tint can occur. Leave-in time of 0.5 to 4 hours determines depth of colour; longer or repeated applications give darker results. Colour longevity averages 3 to 4 weeks on roots but can become more persistent on porous, weathered lengths. Remove product build-up with a clarifying shampoo before use and always strand test a root-to-tip section to check outcome. Colour deepens over hours and days as it oxidises. Chemical lightening affects results and bleaching after indigo use is not recommended unless the dye has faded or grown out; if attempting bleach, strand test first.

For a natural darkening option, choose Indigo Black from Holland & Barrett; follow in-box instructions and strand test guidance to achieve the best, safest results.

Advisory Information:For external use only. Read the instruction leaflet carefully and use only as directed. Keep out of the reach of children. Patch test before use for 24-48 hours with a small amount of paste on your inside elbow covered with a plaster. Wait 48 hours. In the unlikely event of a rash or irritation, discontinue use. Avoid getting the hair colour paste in your eyes - if this does occur flush thoroughly with water. Do not breathe in the powder when mixing. Read and carefully follow all the instructions enclosed in the pack. To summarise, the Herbal Hair Colour powder is mixed with warm water before application. The paste is left on your hair for 1 to 3 hours depending on the depth of colour required. We strongly recommend doing a strand test first before putting the colour all over your hair, because the colour result can be different on different people's hair. You should wait 24 hours after the strand test to see how the colour develops, because it oxidises and darkens over time.
