Allergens used for patch testing in the hairdressing series vary between dermatology centres in the UK. The aim of our study is to ascertain the hairdressing allergens currently in use and their test results in several dermatology centres in the UK. Data were obtained from databases in 9 dermatology departments. The allergens with positive results and current/past relevance were included in a new hairdressing series based on collective experience, for wider use and further evaluation.

Allergy to hair products is an increasingly common issue among people given the exposure to these products on a daily basis. Allergic reactions could be in the form of delayed-type contact dermatitis or the form of immediate-type hypersensitivity reactions. Hair products contain many ingredients and chemicals that patients may have allergies to, but common allergens are hair dyes, fragrances, persulfate salts, ammonium thioglycolate, coconut fatty acid derivatives, and acrylates.

However, not all individuals develop allergic contact dermatitis (ACD) although they are regularly exposed to PPD. It is unclear whether these asymptomatic individuals are true non-responders to PPD or whether they mount a response to PPD without showing any symptoms.

Background: Previous studies reported a low-to-moderate benefit from patch testing regarding allergen recall and avoidance.
Objectives: To determine the allergen recall and avoidance rates of patients with allergic contact dermatitis (ACD) in Turkey.
Methods: This was a retrospective cohort study based on a phone questionnaire of 465 patients diagnosed with ACD from major allergen groups, that is, metals, preservatives, rubber, fragrances (ubiquitous allergens) and hair dye/black henna, topical drug and resins (nonubiquitous allergens), at our tertiary referral centre between 1996 and 2018.
