I let it soak in water and vinager for half n hour and then wash it with a shampoo and let it hang dry until next day.
The water is always brownish when I rinse it and it eliminates left over dyes and other chemicals that make my scalp itch.
I plan on getting some cornrows sometime next week, I'll try that. Will it work for human hair Yaki? Can you do it to all hair types, excluding synthetic?
