If you are looking for great quality and affordable “virgin” hair, then our Black Line Extensions are some of the best that you could get. While some clients can bleach it to #613, our recommendation for our Black Line hair stands at #27. With good hair care the hair lasts up to a year. The weight of the bundles is around 100 grams with rubber band, and 95 gram without. The fullness of the bundles is on the higher end of single drawn. Any higher and it will generally get called double drawn.
