Use a gentle shampoo and heavy-duty conditioner to lock moisture into your hair. Avoid shampoos with surfactants or sulfates, as these can damage your hair. Do not rub the hair too hard as this can cause breakage and frizz. Simply squeeze sections of the hair with a microfiber towel to remove excess water. A microfiber towel works best to absorb water and reduce frizz. These combs typically have wider teeth so they will detangle your hair without snagging. Follow with a finer-toothed comb to smooth the hair further. The pigtails should start near the nape of your neck; higher pigtails will cause more kinking in the hair as it dries. Secure with elastic hair bands. Every 2 to 3 inches (5.1 to 7.6 cm), wrap an elastic hair band around each pigtail. Don’t wrap too tightly or you will create bumps in the hair as it dries. You should end up with what look like “striped” pigtails. Secure with a few bobby pins. The silk will help keep your hair from tangling as it dries, reduce beneficial moisture loss, and will also help reduce frizz. You can sleep comfortably in this style, or do it first thing in the morning if you don’t have anywhere to be for a few hours. Comb through with a wide-toothed comb. Avoid using a bristle brush, at it might encourage frizzing.

TL;DR in Vietnamese:
Gội đầu và dùng dầu xả cho tóc. Dùng khăn bóp nhẹ để thấm khô nước trên tóc. Dùng lược gỡ rối để chải tóc. Chia tóc thành hai phần để cột. Cột thêm vài dây cột tóc cách khoảng dọc theo tóc. Quấn khăn lụa quanh đầu. Cuối cùng là tháo khăn, kẹp tăm và dây cột tóc.
