Rachel runs the spinster net facebook page, and has been dying her hair with henna and indigo for some time, and she gets a great blue / black colour. I’m delighted that Rachel has agreed  to share her recipe here, and it is outlined below. If you are inspired to try henna and indigo on your hair check out the pack available at hennacat (always do a strand test).

Henna will dye hair red with tones from auburn to mahogany depending on your natural hair colour. The intensity will depend on how long you leave it on for, the quality of the henna and your hair type.

Indigo is a blue dye but will only give a blue rinse to white hair when used on its own. When mixed with Henna powder it can dye hair differant tones of brown and red brown. When used immediatly after Henna it can dye hair black or blue black.

1. Step One: Henna your hair (stage 1 of Indigoing hair)

You will need

  • Henna powder, non metalic bowl, wooden spoon, hot water
  • moisturiser/barrier cream, rubber gloves, plastic carrier bag or cling film
  • 2 large old towels
  • up to 5 hours to spare
  1. Mix the Henna powder with hot water
  2. Move or cover things that may get stained accidently
  3. Apply moisturiser all round the hair line to avoid staining face, neck and ears
  4. With and old towel around shoulders and wearing gloves apply Henna paste to hair
  5. Wipe off any stray Henna with a clean damp cloth
  6. Wrap hair in carrier bag or cling film
  7. Shake any stray Henna off the towel and wrap
  8. I then place the 2nd towel over my pillow and go to bed/ wait your chosen amount of time
  9. In the morning/after your chosen time rinse out Henna till water runs clear and towel dry

Stage 2: Indigo your hair

Indigo will not do much to your hair on its own so first you will need to Henna your hair – See above- Hennaing your hair (stage 1 of Indigoing hair).

I Henna my hair at night, go to bed, rinse it in the morning then apply the indigo and go back to bed for 2 hours then rinse. I do this as lying down stops it from dripping – that’s my excuse and I’m sticking to it 😉

The next stage is to apply the indigo to your hair.
