Before you start trimming your hair extensions, have them installed first. Attach the extensions so they match precisely with how you want them to appear, parting your hair as required to achieve the desired look. It is wise to cut while standing up, so you can see how your hair looks as you go. You will be able to see the colour, texture and shape of your extensions better if you cut them while they are dry. This way, you can measure the length and density of your hair accurately, as you decide what style you want. Avoid using standard scissors to cut hair extensions. Instead, it is better to use more specialised tools – if you have them – such as hair shears, hair clips, hair pliers and ties, a fine-tooth comb, and a front and back mirror.
