Both treatments smooth the hair. But comparing them is like comparing a moisturising mask to Botox — a similar visible result, completely different mechanisms. Your choice depends on your hair condition, your goal and how much straightening you actually want. Here's what to consider.
Brazilian keratin — what is it?
Brazilian keratin replenishes the keratin fibre inside the hair. The formula penetrates the cortex, and heat styling with a flat iron sets it into chains. The result is smooth, glossy hair with no frizz.
The keratin formula penetrates the cortex
Heat styling with a flat iron sets it into chains
Result: smooth, glossy, frizz-free hair
Nanoplastia — what is it?
Nanoplastia (nano-restoration) is a newer technology. Amino acids in nano-particles penetrate deeper into the hair structure, filling gaps in the cortex. It's often seen as gentler on the hair than full keratin treatment. Nanoplastia formulas usually contain no formaldehyde, or only trace amounts.
Comparing the key features
Both treatments take a similar amount of time. Both can be used on coloured hair, though it's worth discussing your hair condition with a specialist beforehand.
Ideal for Brazilian keratin
Very frizzy, curly or wavy hair
Goal: strong smoothing and straightening
Thick hair that tolerates chemical treatments well
You want to minimise styling time every morning
You want results that last several months
Ideal for nanoplastia
Weak, damaged hair — from colouring or bleaching
You want nourishment and smoothing, not necessarily full straightening
Curls you want to tame, not eliminate
Sensitivity to stronger chemical treatments
How long should you avoid washing your hair after the treatment?
How to care for your hair after the treatment
Sulphate-free shampoo (SLS-free) — essential; SLS can wash out the treatment effect quickly
Keratin mask or conditioner — extends the effect and nourishes the hair
Heat protection when styling — always, no exceptions
Chlorine (swimming pools) — can damage the effect; a swimming cap is the minimum precaution
Salt water — carries a similar risk to chlorine
Olaplex — what is it, and why isn't it the same thing?
Olaplex isn't a smoothing treatment — it rebuilds disulfide bonds damaged by colouring, bleaching or perming. It works on a completely different aspect of hair structure.
