Final answer:
Chemical treatments should be avoided if the scalp shows abrasions, infections, or inflammation, to prevent further irritation and ensure the integrity of the service.
Step-by-step explanation:
Chemical services should not be performed if the scalp analysis shows any signs of abrasions, active infections, or inflammatory conditions. Performing chemical services on a compromised scalp can lead to further irritation, exacerbation of the existing condition, and can also affect the integrity of the service itself. If any signs such as redness, swelling, cuts, or signs of infections are present, it is important to avoid chemical treatments until the scalp has fully healed.
