About Keratin Treatment
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.
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.
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.
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.
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.
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.
Aftercare Routine for the First 72 Hours
Do not wash, tie up, or tuck your hair behind your ears for the first 72 hours. Sleep on a silk pillowcase and avoid ponytail elastics. After day 3, switch to sodium-free shampoo and conditioner to protect the keratin seal.
What a Keratin Treatment Actually Changes in the Hair Shaft
A keratin treatment coats each strand with a protein film that fills gaps in the cuticle. The coating is sealed with a flat iron at around 230°C. Hair looks straighter and reflects more light because the surface is smoother. The effect is cosmetic, not structural, so the original curl pattern returns as the coating washes out over time.
First 72 Hours After Treatment: Locking the Coating In
Do not wash, tie, clip, or tuck hair behind the ears for 72 hours. Avoid ponytail elastics, caps, and pillow folds that leave marks. Sleep on a silk or satin pillowcase to reduce friction. Skip gym sweat and rain. The keratin film is still soft and any crease pressed into it becomes permanent.
Average Duration of Results on Different Hair Types
On fine, straight hair, results usually last between 2 and 4 months. On thick, wavy, or curly hair, the smoothing effect often lasts from 4 to 6 months. Frequent washing, chlorine, and salt water shorten the lifespan of the coating within days.
