Keratin treatment: Brazilian vs organic, and which one your hair needs
A keratin treatment replenishes the protein your hair loses to coloring, heat and sun, then seals it in with a flat iron: the result is smooth, frizz-free, glossy hair for 3 to 5 months. The classic Brazilian version (also sold as a "Brazilian blowout") gives the strongest straightening but traditionally contains formaldehyde; organic, formaldehyde-free keratin delivers a softer, natural smoothness and is safe during pregnancy.
I apply both at home in Quito, so here is the honest comparison — no marketing — to decide with your hair type in mind.
What does a keratin treatment actually do?
Keratin is the protein your hair is made of. The treatment refills the gaps in damaged fiber and seals the cuticle, which is what kills frizz and adds that glass-like shine. It is not a permanent chemical straightener: your natural texture returns gradually as the product washes out over months.
Brazilian keratin (Brazilian blowout): maximum smoothing
The famous one — and the strongest. It delivers pin-straight, mirror-shiny results even on tight curls, lasting 3–5 months. The catch: classic formulas rely on formaldehyde or releasers to lock the smoothing, producing strong fumes during application.
I only recommend it in ventilated spaces, never for pregnant women or children, and always with reputable professional brands within permitted concentrations.
Organic (formaldehyde-free) keratin: the safe alternative
Formol-free keratins use gentle acids (like glyoxylic acid) and amino acids instead. They smooth about 70–85% as much as a Brazilian, but leave hair visibly healthier, with natural movement — and no irritating fumes, which matters when I work inside your home.
It is the version I apply most in Quito: for wavy or frizzy hair the result is practically identical, and it is the only one I will apply during pregnancy.
Brazilian vs organic keratin: side by side
My honest summary after years of applying both:
| Brazilian keratin | Organic keratin | |
|---|---|---|
| Smoothing power | Maximum (pin-straight) | High (natural, with movement) |
| Frizz | Eliminated | Eliminated |
| Formaldehyde | Yes (classic formulas) | No |
| Pregnancy-safe | No | Yes |
| Lasts | 3–5 months | 2–4 months |
| Typical price in Quito | $100 – $200 | $130 – $250 |
Aftercare: make it last twice as long
The #1 mistake: washing with sulfate/salt shampoos — they strip the treatment in weeks. Use sulfate-free shampoo, avoid very hot water, and space out washes. With good care, a Brazilian lasts 4–5 months and an organic 3–4. You can tie your hair up from 48–72 hours after, depending on the formula we use.

Frequently asked questions
How long does a keratin treatment last?
Brazilian: 3–5 months. Organic: 2–4 months. Sulfate-free shampoo is the single biggest factor in stretching those numbers.
Is a keratin treatment safe during pregnancy?
The formaldehyde-based Brazilian is not. The organic, formol-free version is pregnancy-safe — and it is the one I recommend and apply at home for expecting clients.
Will keratin make my hair completely straight?
A Brazilian gets very close to pin-straight. Organic keratin smooths and de-frizzes while keeping some natural movement — which most clients actually prefer.
What is the difference between keratin and permanent straightening?
Permanent (chemical) straightening breaks the hair’s internal bonds forever and grows out with a visible line; keratin is a temporary, nourishing smoothing that fades gradually. If in doubt, start with keratin — it is reversible.
How much does a keratin treatment cost in Quito?
Salons charge $100–$250. At home with me: Brazilian keratin from $140, organic from $160, free consultation via WhatsApp first.
