About Keratin Treatment
What a Keratin Treatment Does to Hair
A keratin treatment coats each strand with a protein solution and seals it using a flat iron at around 230 degrees. The process smooths the cuticle, reduces daily frizz, and keeps curl patterns relaxed for several weeks. It does not repair broken bonds or stop hair from falling out.
Ventilation Needs and What Those Fumes Mean
Keratin fumes contain aldehydes that irritate eyes and airways. Open at least 2 windows and keep a fan pulling air outward during the ironing stage. Anyone in the home during sealing should wear an N95 mask. A lingering chemical smell after 6 hours means the product was not fully cooked out by the iron.
When to Avoid the Treatment Altogether
Skip the service if your scalp shows open cuts, dermatitis, or active psoriasis. Postpone it for at least 3 months after a keratin straightening with strong formaldehyde. If you have very short hair under 10 cm, the treatment will not hold and is not worth the cost.
Smell, Fumes, and Ventilation During Service
The flat-iron pass releases a strong odor that can linger between 10 and 30 minutes. Keep a window open and step outside if fumes irritate your eyes or throat. Request the stylist to lower the iron temperature by 20 degrees if the smell feels overwhelming.
Questions That Separate a Trained Professional from a Beginner
Ask how many full applications they complete each month and request a portfolio of before-and-after photos. Confirm they measure hair porosity before choosing the formula. Check that they seal at 230°C with a titanium plate, not a ceramic one. A pro who refuses to share the brand name or the safety sheet is skipping safety steps.
Pre-Wash and Product Removal Before the Appointment
Wash hair the morning of the visit using a sulfate-free clarifying shampoo. Skip conditioner, leave-in products, oils, or dry shampoo for at least 24 hours before. The cuticle must be clean so the keratin can bond properly. Any residue blocks absorption and leads to patchy results that show within the first wash.
How to Find a Qualified Professional
Look for a stylist with a keratin-specialist certificate from a recognized academy and at least 200 documented treatments. Ask for a portfolio of before-and-after photos taken under the same lighting. Verify that the professional carries product liability insurance for chemical services.
How to Prepare Your Hair Before the Visit
Wash your hair 24 hours before the appointment with a sulfate-free clarifying shampoo. Do not apply conditioner, oils, or styling products that day. Arriving with clean, dry hair helps the solution bond correctly during the flat-iron seal.
Compatibility with Color-Treated or Bleached Hair
Keratin can be applied over colored hair, but timing matters. Wait at least 2 weeks after any chemical service, including dye, bleach, or highlights. Bleached hair tends to absorb more product and may darken slightly after treatment. A strand test on 10 hidden hairs is worth doing before committing to a full head.
Active Ingredients Commonly Used and What to Ask the Pro
Traditional formulas contain formaldehyde or methylene glycol, which release gas during ironing. Newer versions use glyoxylic acid or cysteine derivatives. Ask the professional which system they carry, request the safety data sheet, and confirm the formaldehyde level stays under 0.2% if you want the gentler option.
