DO NOT apply eyelash extensions on yourself. This adhesive is not for beginners. Many states require a cosmetology or esthetician type license to apply eyelash extensions – it is the buyer’s responsibility to comply with local regulations. **Important Safety Information:** The eye area is extremely delicate and more prone to reactions from sensitivities or allergies than other parts of the face. Some adhesives may release fumes that can cause a stinging or burning sensation. During the consultation, assess whether your client may be sensitive to the products used. Always conduct a patch test on new clients at least 24 hours before the full application—ideally 48 hours in advance. Please note that a negative patch test does not guarantee your client won't react during a full lash extension service. Open and honest communication is essential to ensure your client understands all potential risks associated with eyelash extensions. _Return Policy: First-time buyers may return the adhesive within 30 days for a full refund. The glue must be physically returned to Lash Stuff at 2367 Rulon White Blvd., Ogden, Utah 84404.
