    The objective of this research was to "determine the concentration of formaldehyde in cosmetic hair straightening products sold at the 'FEVACEL' Central Market in the Independencia District in July 2018." The methodology used was a basic research type, with a quantitative approach, a quasi-experimental design, and a descriptive and prospective level. The population consisted of branded cosmetic hair straightening products sold at the 'FEVACEL' Central Market. The sample included 25 cosmetic hair straightening products, with 5 samples taken from each brand. Results indicate that the analyzed cosmetic straightening products tested positive in the qualitative formaldehyde test, with values ranging from 155 ppm to 221.6 ppm, and an average formaldehyde concentration of 184.26 ppm. It is concluded that the formaldehyde concentrations in Keratimask Kativa and Wellastrate cosmetic straightening products are within the permitted limits. However, the Lanostrate and Biokeratin brands exceed the maximum permissible value of 0.2% (2,000 ppm), with concentrations of 221.6 ppm and 210.5 ppm, respectively.
