Unfortunately, if you already had an allergic reaction, it is more likely that you will have it again. Most of the clients that had an allergic reaction in the past, experience discomfort and itchiness during next treatments. Please remember that an allergic reaction is something you can develop at any point while having your lashes done, despite having it previously done or after the patch test procedure. If you experience, any discomfort, itchiness or redness around eye area after your treatment, please see your GP immediately and get in touch with the salon.
