I dont offer express lashes, can do them but have no need for them.
I offer Semi Permanent Eyelash Extensions and no other type of extensions. For me it works, there isnt a market for express lashes in my area, however, that may not be the same for other areas of the country.
Dont know if that helps lol xx
What you have to remember about express lashes is that they will need to be removed and replaced after two weeks, some clients wont want to come back for removal and this is what can cause natural lash damage. Although it does work for a lot of therapists x
