Punch shares an article about using pantyhose to help wash dreadlocks in the first few weeks that you are forming them. The idea is that the pantyhose keeps the hair in place while you wash, but it still allows the shampoo and water to go in and out.
I think that it would be an interesting experience. I think that it would take a lot longer to wash, though, but I bet that it would be worth it to people, who want dreadlocks.
Thank you for reading!
