Cleaning brushes for eyelash extensions are tools specifically designed to clean and maintain the integrity of eyelash extensions. They are typically made of soft bristles or silicone and are used to gently remove any makeup, oil, or debris from the lashes without damaging the extensions. The brushes come in different shapes and sizes, some of which are angled or curved to fit the shape of the eye and lashes. Regular cleaning of the brushes helps prolong the life of the extensions and ensures they maintain a natural and fluffy appearance.
