I tried both. First the Dye Remover in hot water, dipped hairpiece hair for several minutes and nothing!

Then these bleaching products.

I followed the instructions to mix, put a couple of strands of hairpiece hair in the mixture for 15 minutes and it did absolutely nothing!

Am I using wrong products? The hairpiece hair color is #1.
