So the outcome was, no paint on her locs! I checked later, and the paint was still on the beads. No pink locs. The next trial was last night. I oiled the braid with jojoba and coconut oil and even rubbed the beads back and forth. I checked if any paint had scraped off, and it hadn't! This is the acrylic craft paint I used, by the way. I haven't tried the stain yet. With the acrylic paint, you need a couple coats.
I can't speak to ALL hair products, but these did fine with the coconut and jojoba oil...so far. If anything changes, I'll let you know. If you try it and have anything to add, please tell us!!!
(the incoming teeth crack me up!)
