This can happen particularly in Winter due to the use of heating, which makes the air drier. Fumes from the glue are attracted to humidity and when the room is dry, will be attracted to the eyes, nose, and mouth, which can create irritation. We recommend the use of a humidifier in Winter to counteract this. Another reason could be that if your clients eyes were half open during the treatment, fumes could easily go into the eyes. In this case, your client can get chemical burn- red line, which can be mixed with allergy. Make sure your clients eyes are properly shut throughout the treatment.
Being a lash artist is not easy. Clients always think that they’ve reacted to glue, but this is not always the case. Sometimes they can react to a cleanser, primer, eye pads etc. Always read the ingredients listed on the product, as your client may be allergic to one of them. Even if you do everything correctly, your clients may develop sensitivity/allergy, as we are using chemicals. Direct them to see a doctor.
