Our High Definition frontals Lace Frontals are the Ultra Thin lace. Our ultra thin lace has a natural hairline and very tiny knots making this frontal look completely undetectable once installed giving you the perfect scalp Illusion. We recommend letting a professional stylist install your lace, but it's also beginner friendly as well. Frontals last about 4-6 weeks or longer, but they will need to be replaced after each installment.
