Wet hair, especially curly hair types, is more vulnerable to damage. Be gentle when massaging wet hair and avoid vigorous rubbing. Make sure nails are filed so they do not get caught in hair and break it. Be careful when massaging hair dry with oils, as too much pressure and friction can damage wet hair strands. Also, be mindful of added essential oils that stimulate the scalp, as these can leave someone, especially the one new to head massages, light-headed.
