The best way to get your ponytail in instead of trying to fight with all the hair at the back is lean forward and brush all your hair down to your face. Bring all of the hair from the back forward. Once you have done this then you can gather all of your hair in one bunch and apply the holder that you are going to be using.
Now many people would use elastics but if you are going to use these then make sure that they are coated or covered in material such as scrunches for example. Once you have done this, you can stand back up straight and adjust your ponytail to exactly where you want it to hang from. Some individuals like a ponytail that will hang almost from the top of the head whereas others like it in the middle section of the back of the head and some even lower. This is going to come down to the type of look you want and if you are going to do anything further as far as styling with your ponytail
