This is helpful information. I’ve had keratin treatments in the past (fewer than 10), but also had breast cancer at 38 with no family history. Studies like this always catch my attention, but what you’ve just offered is even more interesting. My stylist always insisted that the salon was using the “safe” keratin treatments, yet the smell/feel/inhalation of fumes always concerned me.
