Chemical straighteners and hair curling products are safe according to the manufacturers who make them. However, be sure to read all directions carefully. Follow the manufacturer’s instructions. Do not use the instructions from one product and apply it to another product. Companies formulate their products differently for a reason. They want consumers to have optimal results. By following the instructions provided with the product, this should be easy to achieve. When it comes to using chemicals on a child’s hair, I strongly suggest waiting until the onset of puberty, or when a child has reached the age of maturation. By this time, fluctuating hormones, skin issues, hair changes and other concerns have tapered off and the child’s growth has become more stable and regimented.
