Is Keratin OK for Hair?
Keratin treatments can be beneficial for some, but also pose potential risks. The safety and effectiveness depend heavily on the specific product used and the application method.
Keratin is a naturally occurring protein that's a key component of hair. Keratin treatments aim to smooth and strengthen hair, reducing frizz and improving manageability. However, many commercially available keratin treatments contain formaldehyde or formaldehyde-releasing agents, which are potential irritants and have been linked to health concerns. Environmental Working Group warns that Brazilian-style keratin treatments using formaldehyde or formaldehyde alternatives are not safe.
Benefits of Keratin Treatments
- Reduced frizz: Keratin treatments effectively smooth the hair cuticle, minimizing frizz and flyaways. InStyle highlights this as a major benefit.
- Improved shine: The treatment can create a glossier, healthier-looking appearance. Harper's Bazaar notes that keratin temporarily bonds hair together, enhancing shine.
- Increased manageability: Hair becomes easier to style and maintain after a keratin treatment.
Potential Risks and Downsides
- Hair damage: The high heat and chemicals involved in many keratin treatments can lead to dryness, brittleness, and breakage. The Environmental Working Group and multiple sources (Reddit r/HaircareScience, Vogue, Quora) emphasize the potential for damage with repeated use or harsh treatments.
- Formaldehyde exposure: Some keratin treatments contain formaldehyde, a known carcinogen. Proper ventilation is crucial during application to minimize exposure. Reddit r/HaircareScience discusses the importance of formaldehyde-free formulations.
- Hair loss: Prolonged use or harsh treatments may contribute to hair loss. Quora mentions this as a potential long-term effect.
Choosing a Keratin Treatment
Opt for treatments that are formaldehyde-free and use them sparingly. Consult with a stylist experienced in keratin treatments to assess your hair's condition and suitability for this type of treatment. Cleveland Clinic and Byrdie recommend caution, especially for those with sensitive skin or damaged hair.
