The American cancer society recently put out a warning that many keratin treatments have been found to contain high levels of formaldehyde (known carcinogen). It is marketed as being a “natural treatment” so many aren’t aware that they should even check for toxic ingredients. I would tell her to make sure it’s an organic brand of keratin treatment and review the ingredients thoroughly or switch to another method of hair maintenance.
