Our Lace Frontals are 13x4 10A 100% human hair. You have the option to choose from either a Classic Frontal which is made with an thin light brown transparent lace or HD (High Definition) Frontal made with a thin almost see through lace. Both Frontals are available in a number of our standard lengths (12-20"). Our closures can last up to 2 years+ with the proper care. We highly suggest wearing a silk head wrap or bonnet such as the Bossy Bonnets and Head Scarfs that can be found under “The Beauty Tools Collection. This hair can be bleached, dyed and/or straightened.
