What relaxer ingredient requires the use of a base cream on the scalp to prevent irritation?

Sodium hydroxide is a highly alkaline ingredient commonly found in relaxers and is known for its strong effects on the hair structure. The reason a base cream is necessary when using sodium hydroxide relaxers is to protect the skin on the scalp from potential irritation or chemical burns. Sodium hydroxide can raise the pH significantly, which can be very damaging to sensitive skin, especially if it comes into direct contact with the scalp.

Applying a base cream creates a barrier that minimizes the risk of irritation while allowing the relaxer to work effectively on the hair. The protective base cream typically contains oils and other soothing agents that can shield the scalp from the harshness of the chemical. This is crucial for safe application and to prevent discomfort during the relaxing process. Understanding the importance of using a base cream in conjunction with sodium hydroxide helps maintain both hair health and client comfort during chemical services.
