A rash or swelling on the skin is a key indicator of a possible allergic reaction during a beauty service. Allergic reactions are typically the body’s response to allergens, which can be present in various products used during beauty treatments, such as hair dyes, skin treatments, or cosmetics. When the body detects a substance as harmful, it releases histamines and other chemicals, leading to symptoms such as redness, swelling, and the formation of rashes. Recognizing these signs is crucial for professionals in the beauty industry to ensure client safety and to take appropriate measures, such as discontinuing the product or service and advising the client.

In contrast, dryness of the skin can indicate a variety of conditions such as dehydration or irritation but is not specific to allergies. Increased oil production is often related to skin types and hormonal changes, rather than allergic reactions. Hair breakage, while possibly indicative of damage from harsh chemicals or improper care, does not signify an allergic response. Understanding these distinctions helps beauty professionals to respond effectively to their clients' needs.
