What service are eyelash technicians specifically permitted to provide?

Eyelash technicians are specifically trained and permitted to provide eyelash extension services. This specialized training focuses on the application of individual or cluster lashes to enhance the length and fullness of a client's natural eyelashes. Eyelash extensions require a particular skill set, including the knowledge of proper adhesive usage, application techniques, and understanding the health and integrity of natural lashes.

The other options involve services that may require different training or licensure. Eyelash curling, while related, may not fall under the specific scope of work defined for eyelash technicians, as it could involve tools or methods not typically covered in their training. Facial treatments and eyebrow shaping also fall outside the scope of eyelash extension specialists, as they involve broader techniques and knowledge regarding skin care and facial anatomy, which are usually part of esthetician or cosmetology training. Therefore, the focus on eyelash extensions as a dedicated service reflects the specialization and skill set of trained eyelash technicians.
