If you’re planning to dye your weave, you should make sure that the product you buy is made of 100% human hair. Synthetic hair will fall apart if you bleach it, or expose it to extreme heat. While “human” means virgin, don’t assume that it’s the same as “virgin”. Before buying a hair weave, the hair goes through many processes. Some of these processes include chemical cleaning, curl imprinting, and more, which can change its color. It’s always a good idea to ask the seller about the process behind each weave’s creation before making a purchase.
