XXXHAIR LLC hair comes from a Southeast Asian country that is directly from Vietnam. We proudly provide you grade-A quality Vietnamese hair bundles cut from donor's temple, followed by hand sewn wefts. Then cleansed with organic shampoos and deep conditioned with stemmed natural herbs. Straight hair is the main texture of most Vietnamese donor's. Please note when hair bundles are washed, a slight "wavy" pattern may appear. Which can easily return to its straight texture, by flat ironing on (450-480 degrees). Making sure to use "hair heat protectant spray/serum" before applying hot irons. Bundles may last you 1-2 years after first wear. ONLY if properly maintained. We recommend following our "Hair Care Tips" which is packaged with each hair order.
