What should a cosmetologist do if a client shows signs of a severe allergic reaction?

When a client shows signs of a severe allergic reaction, it is critical for a cosmetologist to seek medical assistance immediately. Severe allergic reactions, also known as anaphylaxis, can escalate quickly and may involve symptoms such as difficulty breathing, swelling of the throat, rapid heartbeat, or loss of consciousness. Time is of the essence in such situations, and professional medical intervention is necessary to ensure the client gets the appropriate care.

While applying an ice pack may provide temporary relief for certain mild reactions, it is not suitable for severe allergies, as it does not address the underlying issue. Continuing the service could put the client at greater risk, as exposure to the allergen may worsen their condition. Offering water is also not a proper response, as it may not help alleviate the symptoms and could delay critical medical attention.

Hence, the most appropriate course of action is to prioritize the client's health by obtaining emergency medical help without delay.
