For at least 48 hours and up to a week before your treatment, avoid blood-thinning medications and supplements (with your doctor’s permission), as well as NSAIDs, alcohol, and anti-inflammatory medications. You do not need to shave your hair before your treatment. On the day of your session, plan to arrive with clean hair free of any gels, sprays, or styling products. Please follow the advice of your PANDERMA practitioner.
