About Keratin Treatment
How to Find a Qualified Professional
Look for a stylist with a keratin-specialist certificate from a recognized academy and at least 200 documented treatments. Ask for a portfolio of before-and-after photos taken under the same lighting. Verify that the professional carries product liability insurance for chemical services.
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.
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.
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.
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.
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.
Pre-Wash and Product Removal Before the Appointment
Wash hair the morning of the visit using a sulfate-free clarifying shampoo. Skip conditioner, leave-in products, oils, or dry shampoo for at least 24 hours before. The cuticle must be clean so the keratin can bond properly. Any residue blocks absorption and leads to patchy results that show within the first wash.
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.
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.
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.
