The first is tethering. The biggest advantage of this method is that it is inexpensive, it can save a lot of money compared with others, and it is also extremely convenient to disassemble. Simply cut the rope and the place where your hair was originally tied. You can do this by yourself even if you don't have to go to the barber shop to find a hair extension manufacturer. The disadvantage is that the cord is easy to see, because it is directly tied to their hair.
The second kind: patch hair extensions. This method is to layer one's hair, and then select a thin layer of hair and then attach two pieces of hair above and below. The advantage is that it's not easy to see, and it doesn't feel very out when you sleep. But the disadvantage is that the process is more painful, you must use professional glue. And you have to take it down to the barber! In THIS PROCESS CAN DROP A LOT OF HAIR, AND MUST WAIT UNTIL THE GLUE ON THE HEAD IS REMOVED. THE PROBLEM THAT FALLS HAIR SIMPLY CAN END. IT IS TO LAST THE TIME OF A WEEK OR VERY COMMONLY.
The third kind: braid is connected. This kind of hair extension is also divided into layers of hair, and then a lock of separate braids. The advantages are extremely stylish and extremely strong. If you do not deliberately pull hard, it will not come off. Disadvantage IS THE MEETING AFTER RECEIVING THE HAIR APPEARS THE HEAD IS EXTREMELY LARGE, BECAUSE BE NOT A ROOT PLACE IS CONNECTED HOWEVER BRAID THE REASON THAT RECEIVES.
