Eyelash practice mannequin head will be a perfect tool for eyelash extension training. The shape and texture are similar to a human, so it will be an easy switch from the training head to your actual clients.
The head comes with super long lashes. You can cut them to the desired length. For beginner level, leave the lashes longer, for advanced level, cut them shorter, per your preference. Apply extensions to lashes, remove and practice again.
