What is the primary component of most hair products that could cause an allergic reaction?

Fragrance is often the primary component in many hair products that can trigger allergic reactions. This is due to the fact that fragrances can contain a complex mixture of various chemicals, which may include synthetic compounds that some individuals may be sensitive or allergic to. The variety of substances in fragrances means that it can provoke a range of reactions in sensitive individuals, from mild irritation to more severe allergic responses.

While herbal extracts and mineral oils can also cause reactions in some, they are less commonly associated with widespread allergic responses compared to fragrances. Water, on the other hand, is typically considered safe and is not a common allergen. Consequently, fragrances stand out as the major culprit in many cosmetic and hair care product allergies.
