Chemical relaxers are strong formulations used to straighten curly or wavy hair, and they contain ingredients that can alter the hair structure. A main contraindication for their use is if the client has had a recent chemical service or is experiencing scalp irritation. Recent chemical treatments can leave the hair in a weakened state, making it more susceptible to damage from additional harsh chemicals. This increases the risk of severe hair breakage and scalp burns, as combining multiple chemical processes in a short timeframe can be damaging.

Scalp irritation further compounds this issue. Using a chemical relaxer on an irritated scalp can lead to pain and severe adverse reactions, including burns or allergic responses. Therefore, ensuring that the scalp is in good condition and that enough time has passed since any prior chemical treatment is essential for the safety and health of the client's hair and scalp.

Avoiding the application of chemical relaxers under these conditions is crucial for the overall wellbeing of the client and the integrity of their hair.
