2 T. Colorant*
1/2 t. Kaolin Clay
1 T. Witch Hazel
1/2 t. Arrowroot Powder
1/2 t. Water
*Oxides and Bramble Berry neon pigments worked best, but micas didn’t really work at all – they just crumble apart.
Mix dry colorant and kaolin together in a bowl big enough to stick both hands in.
Place arrowroot and water in a separate small container and microwave for 5 seconds. You do not want it gummy, just slightly thickened. If it’s not thick after 5 seconds, try again on three second bursts.
Add the witch hazel to the dry powders, and hand mix together (while wearing gloves!). Once well mixed, add arrowroot powder and water slurry. Really squish the mixture together. You don’t want it crumbly or wet, or to have bits of undispersed clay. It should have texture just like kid’s modelling clay. If it is too dry, spritz witch hazel one spritz at a time until correct consistency is reached.
Roll mixture on a piece of parchment paper until you get the shape you like. Allow to air dry overnight.
To Apply Hair Chalk
Put an old sheet or towel over the shoulders of the person you’re applying the color to. Wet designated area of hair desired to be chalked. We used a spray bottle of water.
Wearing gloves, apply the chalk to the wet area by dragging it along the strands. Use your fingers to rub the chalk into the hair really well.
Heat-set the chalk using a blow-dryer, curling iron, or straightener. A curling iron or straightener may not be the best idea for those with damaged hair. You can also straighten or curl the hair after you blow-dry it.
Spray chalked hair with hair spray so that it doesn’t brush off onto clothing.
