Understanding Hair Coloring Side Effects

Hair coloring is a chemical process that involves altering your hair's natural pigment. Like any chemical process, it can cause side effects, ranging from minor to severe. These reactions can be due to the hair dye itself, the developer, or allergies to specific ingredients.

Allergic Reactions: While rare, some individuals may have an allergic reaction to hair dye, leading to symptoms like hives, itching, or difficulty breathing.
