Clients ask me this almost every week, usually with some version of: "Aren't they all just... keratin?" Not quite. The three treatments work through genuinely different mechanisms, and picking the right one changes both your results and how long they last.
Here's the honest breakdown.
Keratin Treatments
Keratin treatments — including the vegan formula I use — coat and seal the hair's outer cuticle layer with a protein-rich formula, then lock it in with heat. The cuticle lies flatter, light reflects more evenly, and frizz has a much harder time forming. It's the most classic smoothing method, and a strong first choice if your hair is generally healthy but reactive to humidity.
Results last: 3–5 months
Best for: frizz control, shine, cutting down daily styling time.
Hair Botox
Despite the name, there's no actual botulinum toxin involved — it's a deep-conditioning treatment that fills the hair shaft from the inside with a blend of proteins, amino acids, and vitamins, rather than just coating the outside. That makes it gentler than keratin and a better match for hair that's dry or a little fragile, not just frizzy.
Results last: 2–4 months
Best for: softness, added moisture, lighter-touch smoothing.
Nanoplastia
Nanoplastia uses smaller molecular particles to restructure the hair from within, at lower processing temperatures than traditional keratin. That makes it the gentlest of the three, and often the best option for fine, sensitized, colour-treated, or previously over-processed hair that needs smoothing without more stress.
Results last: 4–6 months
Best for: fine or compromised hair, colour-treated hair, longer-lasting results with less heat.
Two more worth knowing
Protein Treatment — less about smoothing texture and more about structural repair, rebuilding the internal bonds that heat and colour break down. A good pairing treatment for hair that's breaking or over-processed. Results last 8–12 weeks.
Japanese Straightening — a permanent restructuring treatment for maximum, long-term straightness. Unlike the others, it doesn't fade — it grows out, so touch-ups happen at the root as new hair comes in.
So which one is right for you?
Honestly, it depends on your hair's current condition more than what you'd guess from the name. That's why every appointment starts with a real consultation — I look at your hair's history, density, and goals before recommending anything. The right treatment isn't the most popular one; it's the one that matches what your hair actually needs right now.
