One-page reference card for patch testing protocols in salons.
The 48-hour patch test is the clinical standard for predicting allergic contact dermatitis before salon chemical services[1]. Applied to the post-auricular area or inner elbow, a small amount of the exact product to be used is left in contact with skin for 48 hours. In any country, the cosmetics authority’s guidance specifies when patch testing is mandatory or recommended[2].
