You guys have asked for a dye guide and here it is! We used Rit DyeMore fabric dye, Rit's line for polyester/synthetic materials (not to be confused with just Rit Dye). It is far more pigmented as a wig toner than their standard blends since it was developed for plastics.
Swatches were made using our Classic White wefts (keep in mind that if you're dyeing a wig other than white, the dye will not cancel out the original color but mix with it. ex: If you dye a yellow wig with blue dye, you will get a green wig).
300 mL (1.3 cups) of water was used with 19.7 mL (4 tsp) of dye. Water was kept at a LIGHT SIMMER (180F/82C), NOT rolling boil (212F/100C). Color took more evenly when water was at a simmer.
Individual swatches were placed in the simmering water at 1 second, 5 seconds, 1 minute, and 5 minutes.
Colors may turn out differently for you depending on concentration of dye, heat, time boiled, and how the wig gods are feeling that day.
It's important to ALWAYS do swatch tests before dying your full wig. In addition, in the event that your fibers become curly after dyeing them, please use a regular flat iron (avoid chi irons) on low heat setting to straighten them.
