About Keratin Treatment
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.
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.
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.
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.
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.
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.
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.
Compatibility with Colored or Bleached Hair
Keratin treatments can be applied over color, but bleaching within 7 days weakens the cuticle and raises break-off risk. Wait at least 2 weeks after any chemical service before booking. Use a protein mask 5 days before the appointment to reinforce strands.
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.
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.
