Lash shampoo is a specially formulated cleanser designed to clean and maintain the hygiene of eyelash extensions. It gently removes dirt, oil, makeup residue, and debris from the lashes and the lash line, helping to prevent buildup that can lead to infections, irritation, or premature lash shedding. Using lash shampoo regularly keeps the extensions looking fresh and helps prolong their lifespan while also promoting overall eye health.
