In the realm of hair straightening, a chemical process is employed to permanently alter the hair’s structure, reducing curl and wave patterns. During this treatment, a protective substance is frequently applied to the scalp prior to the application of the straightening chemicals. This barrier aims to mitigate potential irritation and chemical burns. An example would be the application of petroleum jelly to the scalp before a sodium hydroxide relaxer is used.
The strategic application of this protective barrier is crucial for client comfort and safety. It minimizes the risk of scalp sensitivity and damage often associated with potent chemical straighteners. Historically, such precautions were not always standard practice, leading to increased incidents of scalp irritation. Modern techniques prioritize these safeguards as an integral part of professional chemical straightening services.
