Unfortunately, if you’ve ever had any type of irritation or reaction after having eyelash extensions applied, you won’t be able to get them anymore. If you are a person who regularly suffers from eye irritation from hayfever, or if your skin is very sensitive to cosmetic products, it’s probably not a good idea to have extensions applied. Also, we ask clients with any type of eye infection or contagious illness to wait until they are completely symptom-free.
