Examining the Safety of Keratin Hair Color
Keratin hair treatments aim to repair damage and provide smoothing benefits using a formaldehyde derivative called methylene glycol. However, questions exist around whether keratin hair dyes cause similarissues as traditional oxidative color.
What is Keratin Hair Color?
Rather than lifting cuticles to deposit pigment like permanent hair dyes, keratin color treatments feature premixed colors that coat strands via a bonding process with the signature keratin proteins. This may offer gentler, safer results.
Benefits of Keratin Hair Color
Compared to traditional ammonia/peroxide hair dyes, touted advantages of keratin hair color include:
- No harsh chemicals damaging follicles
- Less scalp irritation potential
- Minimal hair cuticle lifting for less porosity issues
- Color washes out easily without regrowth lines
Drawbacks of Keratin Color
However, keratin hair color does feature some considerations including:
- Higher cost for initial and touch-up treatments
- Color predictability and accuracy challenges
- Fading issues between appointments
- Overlapping with other services causes challenges
Examining the Safety Profile of Keratin Hair Dyes
Most keratin hair smoothing products contain formaldehyde despite "formaldehyde-free" claims. But at permitted lower levels, is this still deemed safe?
"Safe" Formaldehyde Regulations
The FDA mandates cosmetics contain no more than 0.2% methanol glycol (pure formaldehyde), while OSHA enforces air levels below 0.75 ppm during treatments. Many argue these trace amounts pose little health or allergy risks for clients or stylists.
Formaldehyde Reactions Still Possible
However, studies show dermal and inhalation exposure can trigger headaches, breathing issues, eye damage or hypersensitivity reactions in formaldehyde-sensitive individuals even at low documented "safe" amounts, especially over time.
Ingredient Detection Issues
Seeking safer alternatives, some brands use "formaldehyde-free" methylene glycol instead. But once airborne, exposure analysis proves this converts to formaldehyde anyway, sparking debate around accuracy of safety claims.
Potential Health Issues Linked to Keratin Hair Treatments
Ongoing investigations analyze if keratin hair dyes and straightening solutions may contribute to client health issues over time.
Hair Damage & Breakage
Repeated overlapping with keratin color treatments tends to dry hair overtime, leading to brittleness, fragility and splits despite the temporary smoothing effects. This worsens with bleach or heat styling.
Skin Irritation
Dermatitis, burning, redness or itching of the scalp or neck may develop from sensitivity to formaldehyde-releasing keratin solutions or fragrances. Patch testing is advised to identify risks.
Respiratory Issues
Repeated exposure to fumes may aggravate asthma or nasal passages. Poor ventilation and protective equipment escalates inhaled intake for stylists performing regular treatments.
Eye Injury
Through airborne exposure or accidental splashing, keratin solutions may damage eye tissue leading to dryness, stinging sensation or impaired vision. Use caution to protect eyes during the rinsing process.
Cancer Concerns
While not definitively linked to keratin hair dyes specifically, the National Cancer Institute warns that regular long-term contact with formaldehyde via personal care solutions may contribute to cancer development.
Safer Options for Temporary Keratin Hair Color
If concerned over risks but seeking temporary smoothing color, safer options exist without formaldehyde or peroxides. Consider these gentler alternatives:
Pure Semi-Permanent Hair Color
Ammonia-free semi-permanent hair dyes simply coat strands with pigment that fades after 4-8 gentle shampoos. No lifting cuticles means less damage for vibrant color.
Natural Plant-Based Hair Dyes
Henna, cassia, indigo, amla and other botanicals tint hair beautifully. Mix them to custom-blend colors while adding shine and thickness too.
High-Quality Rinses & Glosses
Non-permanent color conditioners add luminous hues and mirror-like shine while hydrating. Rinse out easily for lower commitment color.
When possible, allow natural gray hair growth to avoid risks associated with chemical treatments. Evaluate scalp and hair health regularly for any concerning changes while coloring.
FAQs
Does keratin hair color damage like other dyes?
Keratin colors are less damaging short-term but repeated overlapping still causes dryness/brittleness over time. Limit treatments and nurture hair's health.
Can keratin cause an allergic reaction?
Yes, sensitivity symptoms like scalp itching, eye irritation or breathing issues may develop in those with known formaldehyde allergies despite supposedly “safe” levels.
Is keratin treatment safe while pregnant/nursing?
No, exposure to fumes poses undefined risk. The FDA urges avoiding hair dyes with carcinogens like formaldehyde throughout pregnancy and breastfeeding.
What's the healthiest semi-permanent color option?
Pure ammonia-free semi-permanent hair dyes or naturally-derived rinses and glosses offer the safest temporary color with minimal risks.
