Prepping:
Hair needs to be present. Only need a millimetre or 2. Can trim before you come in but need to be able to grab onto hair
Exfoliating a day or 2 before treatment helps insertion and generally taking care of skin with moisturising will help with penetration. Skin turnover is important for skin health and general healing becomes quicker when your skin is turning over well
Minimising adrenaline when coming to a treatment will help with minimising your tension and anxiety and therefore pain. Even coffee and chocolate will stimulate you so will make it more painful.
