There is no guarantee against dye bleeding on all dyed mohair although every batch is processed with extra steps taken with the intentions that it shouldn't bleed dye. All mohair made here has been made per the instructions for setting dye to the best of our abilities, it is tested a final time as it's being made into locks. Although we process every batch to set the dye, and test every batch before being listed, there is no guarantee that it will hold 100%.
Most of our mohair requires dye to obtain a color which means it is not natural. Due to the nature of dye there is no guarantee if it will hold or for how long. We do however use dye that has been advertised to hold its coloration longer than many other dyes.
We cannot guarantee that the dye will not bleed because people have been known to use chemicals on the hair which cause the dye to un-set. This is a chemical breakdown process which causes the dye to 'bleed' even though it was properly set. We strongly advise that you do not use anything harsh on the mohair, as it is very fragile and you do not want to break down the dye structure.
