To use these VLash B Curl lashes, first pick the right length for your client's eyes. You can either apply a full set or mix different lengths and thicknesses for a customized look. Apply a small amount of lash glue at the base of the lashes and carefully place them close to the natural lash line. Make sure they are properly aligned. When it comes to maintenance, avoid getting the lashes wet for a few hours after application. Gently clean them with a mild lash cleaner to keep them looking great. If you notice any loose lashes, don't pull them out forcefully. Instead, visit a professional lash technician to have them fixed. Store the unused lashes in a cool, dry place to maintain their quality.
