Are keratin treatments safe for the hair?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)
Some keratin treatments, marketed for use as hair straighteners or relaxers, contain formaldehyde, a potentially toxic strong-smelling gas that could damage lungs, eyes, skin, and possibly even raise your risk for cancer. The Occupational Safety and Health Administration (OSHA) has found that even some keratin treatments that claim to be formaldehyde free contain formaldehyde by other names on the list of ingredients. In order to avoid a product containing formaldehyde, OSHA recommends reading ingredient lists carefully and avoiding products that contain formalin, paraform, methylene glycol, methylene oxide, formic aldehyde, methanal, oxomethane, oxymethylene, CAS Number 50-00-0 or timonacic acid. Consult your doctor if you have more questions about keratin treatments.
