Clean Skin & Scalp Surface

First) Use Lemon Prep Abrasive Scrub and/or Alcohol Wipe to remove oils, makeup, etc from the surface; this can be done using gauze, Q-tip, glove, or finger. Be Careful to ask about Lemon Allergies!

Next) Remove the Lemon Prep with a tissue, gauze, or paper towel. Add water if needed. Be sure to use non-lotion infused tissues!
