    I’m from London but I live in Singapore now and use a golden blond water colour to do root touch ups as there’s nothing like this in Singapore. My hair always feels really good afterwards like when it’s had a treatment.

    Claire Chaplin

    I’ve been a loyal customer for over 20 years and use the colour when I’m not able to come in. I started buying 5/75 in lockdown to use at home to cover up my greys. It leaves my hair silky soft and shiny, and I wouldn’t use anything else.

    I buy the H2O colour for my partner so he doesn’t look grey. It works without it looking obvious so that no one can really tell.

    I go to the salon when I visit London and have my hair done but always leave with a couple of light brown water colours to tide me over as I love the feel of it and it’s easy to do at home.

    I use the H2O dye at home because it covers my grey and I don’t get a sore head like I do with other colours – I couldn’t do without it. Thank goodness I found it!

CONDITIONING

H20 WATER COLOUR - SALON SHINE AT HOME

Sensitive scalps and stressed hair deserve the gentlest, most conditioning colour.

Traditional home hair dyes can be harsh, causing breakage and itchy scalps.

  • Zero hair breakage
  • Natural looking regrowth
  • Enhance or cover greys
  • Kind to sensitive scalps

Our H20 Water Colour for home-use is a gentle, effective alternative that’s kinder to your hair and skin. Say goodbye to damaging processes and hello to vibrant, natural-looking colour.

CONSIDERATE

H20 WATER COLOUR - THINKING ABOUT THE PLANET

We are on a mission to banish single-use plastics from home hair colours.

We’ve worked hard to find packaging and products that can be reused, composted and recycled in your normal waste collections.

  • Plastic Free Colour Pouches
  • Reusable Cap
  • Reusable Gloves
  • Tint Brush For Life

Our H2O Water Colour comes as a powder to simply mix with water. You can order a cap, gloves, or a tint brush from us or use your own and just order the colour.

SKIN SENSITIVITY TEST

ALWAYS SKIN TEST 48 HRS BEFORE USE

  1. Allergies are personal and a minority of people may react to one of our ingredients. This can change over time, so even if you’ve used Natural Colour Works™ H20 Water Colour before, we recommend that you ALWAYS skin test 48 hours before use.
  2. Take a pinch of Natural Colour Works™ H20 Water Colour powder from the pouch and mix it with a few drops of water in a small bowl. Use a kitchen clip to reseal the pouch immediately and make sure it doesn’t get wet.
  3. Wash a small patch of skin inside your elbow and pat dry. Apply some of the colour mixture to this area with cotton wool.
  4. Allow to dry for 48hrs.
  5. If you feel any irritation, redness, swelling or burning during this time, it’s likely that you’ve got an allergy to one of the ingredients and you shouldn’t use it. 

GET STARTED

Please read all instructions carefully and always protect your clothes and home from colour staining. Use old towels.

What you will need from the kitchen:

  • Clean bottle with lid
  • Measuring jug
  • Bowl

See our video for ideas of what to use!

MIXING

  1. Carefully pour 70 ml or 5 tablespoons of hand-hot water into your clean bottle per pouch of Natural Colour Works™ H20 Water Colour. Don’t over dilute.
  2. Add all the H20 Water Colour powder into your bottle and screw on the lid tight.
  3. Give it a good old vigorous shake for at least 10 seconds until you can’t hear liquid sploshing around anymore. Great for the arms and you now have a bottle of H20 Water Colour foam.

FULL HEADERS

If this is your first time using Natural Colour Works™ H20 Water Colour, or your hair is completely faded out and showing no signs of regrowth, we’d recommend a full head treatment.

  1. Start with clean, dry hair that’s been washed with a clarifying shampoo. Don’t use conditioner or 2-in-1 products.
  2. Apply a barrier cream or Vaseline to the hairline and ears before colouring to help reduce staining.
  3. Wearing water resistant gloves (either ours or your own) pour your Natural Colour Works™ H20 Water Colour foam into a stain resistant bowl and using your tint brush for life apply foam to your roots at roughly 1 cm intervals. 
  4. Give any grey an extra thick covering and massage the left-over foam through the rest of the length of your hair evenly.
  5. Pile your hair up on top and cover with your Reusable Cap making sure to fix it tightly to prevent any drips or hair drying out. 
  6. Leave it on for 90 minutes, then rinse the foam out of your hair until the water runs clear.
  7. Use your usual shampoo to wash and rinse again, then apply your conditioner as usual, rinse, style, and you’re good to go.

GETTING TO THE ROOTS

If you’ve used Natural Colour Works™ H20 Water Colour before and are looking to touch up the roots and boost that glossy shine, follow these simple steps.

  1. Start with clean, dry hair that’s been washed with a clarifying shampoo. Don’t use conditioner or 2-in-1 products.
  2. Wearing water resistant gloves (either ours or your own) pour your Natural Colour Works™ H20 Water Colour foam into a stain resistant bowl and using your tint brush for life apply foam to your roots just to cover the regrowth. Apply it thickly to grey hair and be careful not to go over your last application. Hold onto the rest of the foam for later and pile your hair up on top with a clip. Cover with your Reusable Cap making sure to fix it tightly to prevent any drips or hair drying out. 
  3. Leave it on for 90 minutes, then apply the remaining foam through the rest of your hair, recover with your Reusable Cap and leave for another 15 minutes.
  4. Rinse the foam out of your hair until the water runs clear. Use your usual shampoo to wash and rinse again, then apply your conditioner as usual, rinse, style, and you’re good to go.
