In the context of beauty treatments for pregnant clients, certain chemical relaxers and hair dyes should be avoided due to potential exposure to harmful substances that could affect both the mother and the developing fetus. Many hair dyes contain chemicals, such as ammonia and peroxide, that might be absorbed through the skin or inhaled, raising concerns regarding their safety during pregnancy. Some studies suggest a possible link between exposure to certain chemicals in hair products and adverse pregnancy outcomes, such as low birth weight or developmental issues.

Pregnant clients tend to have heightened sensitivities and may react differently to hair treatments due to hormonal changes. For these reasons, it is advisable to choose products that are specifically marketed as safe for use during pregnancy or consult with a healthcare professional before proceeding with any chemical treatments.

While natural oils, facial exfoliation, and hair trimming are typically considered safe practices during pregnancy, they do not carry the same level of concern as the chemical treatments. Therefore, it is crucial for cosmetologists to prioritize the health and well-being of pregnant clients by avoiding potentially harmful chemicals during any beauty treatment.
