What should be done immediately after completing a chemical service on hair?

After completing a chemical service on hair, it is essential to rinse the hair thoroughly with water to neutralize any remaining chemicals and remove any products used during the service. This step is crucial for ensuring the health of the hair and scalp, as residual chemicals can lead to damage or irritation if left on the hair. Rinsing cleanses the hair and prepares it for any subsequent treatments or styling.

Other options, although they may seem beneficial, are not the immediate priority after a chemical service. For instance, applying a leave-in conditioner should only be done after the hair is rinsed and checked for any potential damage. Immediate styling can put stress on the hair that may already be compromised from the chemical process, while applying heat right after a chemical service can exacerbate damage and should generally be avoided until the hair has been properly treated and assessed.
