DetailsCrepe Wool is synthetic hair that is commonly used for "free laying" facial and body hair. Crepe Wool can be steamed straight, but do not apply direct heat with a flat or curling iron, as this product will melt and burn. Also great for blending into human hair pieces to help add volume and texture. Comes in human hair and primary shades. Each strip is 1 yard (3 feet) long. Comes in 20 shades.
