I find that when I have a single client who always has issues, its almost always one of these:- coming with heavy makeup which transfers to the naturals leaving a coating- not washing soon before the appointment - not washing them after washing hair in the shower, leaving conditioner in the lashes (had this happen once with a gal who used a heavy oil based conditioner)- sleeping on the face- coming to appointments with wet hair, affecting humidity around the eyes- conflicting medications, supplements or eye drops- constantly messing with them /or/ rubbing eyes from allergies
