Although some have raised questions about how safe formaldehyde is, most companies say they put in only trace amounts of the chemical in their solutions. Formaldehyde is a chemical with a strong, irritating odor that is believed to be carcinogenic. Be sure to ask your cosmetologist about the amount of formaldehyde in your Keratin treatment. High levels are dangerous and should be avoided. Any treatment with less than two percent of the chemical, however, won't be effective and isn't worth your money.
So who is a good candidate for a Keratin treatment? Many people with course, frizzy hair that is difficult to work with in humid climates find the treatment highly effective, but cosmetologists say the treatment is beneficial for almost anyone. Even if you already have straight hair, Keratin is able to be a strengthening and restorative treatment.
People continue to praise this “life-changing“ hair treatment. But the cost and safety of the product is important to consider. Have any of you tried a Keratin treatment? Leave us some feedback about the results-good or bad!
