Allergic contact dermatitis is an individual response and can occur at any time in a person’s life. E.g. after first exposure or after many years of exposure.
Allergic contact dermatitis only requires a very small amount of contact with the allergen to cause a reaction and takes days or weeks to heal. It is a lifelong allergy and is diagnosed by patch testing.
Affected people may or may not have a personal or family history of asthma/ eczema/ hayfever.
Common causes of allergic contact dermatitis include:
hair dye
nickel
cement and leather
glues and coatings
preservatives in some products.
