LOL...I would that over poking my dreads hundreds of time with a needle like some else suggested. I wasn't looking to do anything...just seeing how long other people had latex paint stay in their hair. I really think about a month it all... there really isn't that much.
Ohhh ,I've had plenty of paint in my locks, every color imaginable ( I remodel a lot) .....usually it takes a few washings then it will basically disintegrate , then you can pick out all the leftover chunks. But be careful when picking out the pieces cuz it can cause breakage .....
