About Keratin Treatment
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.
How Long the Appointment Takes at Home
Plan for a window of 2 hours and 30 minutes to 4 hours from arrival to rinse. The exact time depends on hair length, density, and how much product the stylist applies. Plan for an extra 30 minutes if a toner or color was done the same day.
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.
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.
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.
Warning Signs of a Bad Application
Hair that feels gummy, brittle, or breaks 2 cm from the scalp points to an overheated iron. Excessive smoke during sealing means the iron sat on one section too long. Request a strand test on a hidden layer before the full pass if you dye your hair.
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.
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.
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.
Working Time Required for a Full Head at Home
Plan for 2.5 to 4 hours in the chair. The professional needs 30 to 45 minutes to apply the product section by section. Rinsing takes 10 to 15 minutes. Blow-drying adds 30 minutes. Flat-iron sealing is the longest step and runs 45 to 90 minutes depending on hair length and density. Long, thick hair can push the visit past 4 hours.
