When should a barber refrain from proceeding with chemical services?

Refraining from proceeding with chemical services when there are signs of irritation or abrasions is crucial for the safety and well-being of the client. Chemical services, which can include treatments like perming or coloring, often involve strong chemicals that can aggravate existing skin conditions, leading to discomfort, burns, or more severe reactions. If a client has open wounds or signs of irritation, applying these chemicals can exacerbate the issue and may even result in chemical burns, allergic reactions, or infections. Therefore, it is essential for barbers to conduct a thorough assessment of the client's scalp and skin condition before any chemical service, ensuring that the skin is intact and healthy to avoid any adverse effects.
