- $99 for one GK Hair Professional hair-straightening treatment ($201 value)
During the treatment, the stylist will apply a keratin formula to your hair and then seal it with a very hot flat-iron. It’s the heat from the iron, along with other chemicals in the keratin formula, that activate the smoothing effect.
Some hair-straightening products that claim to be formaldehyde-free include aldehyde compounds, which are similar to the carcinogen formaldehyde. Side effects may include nosebleeds, headaches, vomiting, and respiratory problems, among others. Learn more about the health risks here.
