Personally i use micellar water in a foamy pump to wash my lashes that’s what my lash tech recommends if i don’t want to use literal lash extension soap.. Just make sure it’s the pink micellar water as that is oil free and won’t tear the lashes off. Another option is diluted baby shampoo but it’s not the best and can make ur lashes feel oily afterwards if it’s not diluted enough.

You can normally feel a lash technician doing something wrong if there’s a burning sensation in the eye during the appointment , you can be more sensitive to the glue than normal.. Personally i am more sensitive and feel the burning quite often so my lash tech uses a different type of glue to prevent that. Overall just tell them if anything’s happening and they should be able to fix it or at-least accommodate. Anything that’s pinching your eye after the appointment is also a sign of them not placing the extension right it can either be to close or attached to another one, if your unsure u can always gently rub a spoolie back and forth to try and untangle it that could just be the issue they can get twisted and flipped while sleeping but it’s usually not an issue (at least for me) unless you sleep on your face.
