About Keratin Treatment
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.
Why Results Last Longer on Some Hair Types Than Others
Coarse, thick, or very curly hair holds the keratin film for about 4 to 5 months. Fine or wavy hair loses it sooner, often after 8 to 10 weeks. Bleached or chemically processed hair absorbs more product but also strips it faster. Heat exposure and wash frequency after the treatment shorten the timeline noticeably.
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.
Red Flags That Signal a Poor Application
Hair feels stiff, straw-like, or gummy immediately after rinsing. Strands break when stretched instead of bending. The coating flakes off in white pieces within 5 days. Roots stay frizzy while lengths look flat, meaning sectioning was uneven. Any of these signs means the formula was left on too long, rinsed poorly, or ironed at the wrong temperature.
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 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.
Price Drivers: Why Quotes Vary by 100% or More
Home visits cost more than salon work because of travel time and setup. Hair length and density drive product use: short hair needs 30 to 40 ml, long hair up to 120 ml. Brand matters too, with imported Brazilian formulas priced higher than local equivalents. Expect a 40% to 60% surcharge for very long or very thick hair.
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.
Products Used and What to Ask About Them
Most kits rely on formaldehyde or glyoxylic acid as the active straightening agent. Ask the professional for the exact brand, the percentage of active ingredient, and the safety data sheet. If you are pregnant or have respiratory issues, request a formaldehyde-free formula.
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.
