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