BTW - Washing brazilian hair bundles would not count as processing, please wash your hair regularly.Bottom Line: When the hair you're looking to buy has had ANY processing steps completed to it, chemical or non-chemical, then it can be not virgin. You should not believe the hype! (Sorry to the Public Enemy reference lol - but I adore P.E.)Remy hair is hair that the extension maker has taken time and expenditure to ensure that every one of the roots and ends in the donor hairs that make up the weft are going within the same direction. This lets the weft to flow and behave like your personal normal hair does. Genuine remy hair is not going to tangle or snag when cared for properly.Bottom Line: When you invest in remy hair online, inspect the product or service carefully and ensure that each of the roots and ends are laid out as I've just described.Also be careful when a hair seller tells you that their hair is "single drawn". Solitary drawn remy 
Brazilian Hair wefts come from a single donor and command the highest grade and price. Solitary drawn purely natural virgin remy hair (grades 6A and higher than) is quite high-priced. You might not come across the real deal at a bargain basement value should the retailer is being honest. I'm just being honest with you. If you're over a budget, (real) grade 5A will do you right. The only difference is Peruvian Hair in how the hair is drawn.
