MJ wholesale wigs are 100% unprocessed human hair. Wigs are expertly produced with full and thick healthy ends! All hair is cuticle-aligned which makes for less tangles and matting. Since units are 100% virgin human hair you can dye and bleach with no problems. Many of the units come pre-plucked with lightened knots and baby hair for a more realistic installation with 130%-150% density. Special requests can be made to increase density to 180%-250% for additional charge.
