We have remy hair (multiple donors) which is devided into 3 qualities: single drawn (thinnest) , double drawn (medium) and super double drawn. of that, super double drawn is fullest hair. Remy hair can't dye well.we also have virgin hair (single donor- with natural thin end) which is ideal for making color. Remy hair and Virgin hair of us are 100% human hair: Remy hair is hair cut from 2-3 people heads, and then we mixed all together so remy hair fuller than virgin hair Virgin hair is hair cut from just only one head and no mix
