Divide your hair into 2-inch (5-cm) sections, starting at the nape and gradually working up the back of the head and around to the sides and front of your hair.  You can either separate all the sections out at the beginning of the process or separate them out as you work. The choice is up to you, but if you are new at this and want to make sure that the sections stay even in size, you might find it easier to separate all the sections out at the beginning. Clip each section back with a bobby pin or other clip. Working one section at a time, apply a dot of hair gel to your natural hair, smoothing it down securely.  The hair gel gives your hair a little extra hold. Using it helps prevent the twist from unraveling when completed. The gel can also help tame some frizziness that may occur after you wash your hair. You can also apply a little gel as you need it during the twisting process. Gel should only be used in small dabs for the purpose of smoothing down stray pieces. Take one section of Marley hair from your package and bend it at the halfway point. Hold it between two fingers at this point so that it forms an upside-down U-shape.  Take this time to separate the strands of the Marley hair. Since the hair comes in tightly bundled sections, separating these sections is definitely necessary. All you really need to do is to pull down on each section a few times until you notice the hair start to unwind or loosen from its bundle. They should still be clumped together well enough to work with when done. You should also play with both hanging ends of the section so that the hair tapers off instead of coming to a blunt, hard stop. Start with a section of hair at the back and bottom of your head. Place the bent center of your Marley hair over the top of your real hair, keeping your real hair in the center. You should be holding three sections of hair in your hands at this point. Braid the three sections together for about 1 inch (2.5 cm). This braid will secure the extensions in your hair. After you braid the hair,...

TL;DR in Indonesian:
Pisah rambut Anda dalam beberapa bagian. Gunakan minyak rambut di satu bagian. Tekuk satu bagian rambut Marley. Letakkan rambut yang ditekuk pada satu bagian dari rambut asli Anda. Kepang di tempat. Lilit rambut di bagian ujung. Ketika menggunting rambut yang berlebihan, gunakan bagian tajam dari pisau cukur dan potong bagian ujung dengan sudut vertikal secara hati-hati. Ulangi jika diperlukan.
