About Keratin Treatment
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
