What could I use to remove hair dye spots from the carpet?

Question:I tried carpet spray foam and it didn't work.:(

Answers:
I used Oxi-Clean to get hair dye out of carpet and it worked like a charm! This was back in the day when you could only buy the powder, (about 3 yrs ago.) I diluted it as per the directions on the tub.
Now, for carpet stains I use an oxygen product that's made for laundry. I think Spay-n-Wash makes it, (one side is clear, the other is pink.) It has two sides keeping the liquids separate until they mingle when squirted.
