I have the solution for hair dye stain removal

Guys I just successfully removed a red auburn hair dye stain from my beige sweatpants.

Within the first 5 minutes of getting the stain spray RESOLVE on it and let it sit for a fee minutes. Then, mix baking soda and vinegar and pour the mix over the stain. It will come off naturally.

I am not sure if it works for all types of fabric but it certainly did the job for me.
