The short answer
Both treatments smooth frizzy hair — but they work very differently. Traditional keratin treatments coat the hair with a protein layer, often sealed with formaldehyde-releasing ingredients. Nanoplasty rebuilds the hair from the inside using nano-sized amino acids and proteins, with no formaldehyde. The result: nanoplasty looks more natural, lasts longer, and is gentler on your hair and scalp.
How each treatment works
Keratin smoothing fills and coats the hair cuticle, then locks the coating in with heat. It delivers a sleek finish, but the coating washes out gradually and the sealing process can be harsh. Nanoplasty's smaller molecules penetrate the hair fibre itself and restructure its internal bonds. Because the change happens inside the hair rather than on its surface, regrowth blends in softly with no harsh line.
How long they last
A keratin treatment typically lasts 2–4 months and fades as the coating washes away. Nanoplasty typically lasts 4–6 months, and because it's structural rather than a coating, it doesn't "wear off" so much as grow out. Aftercare for nanoplasty is also simpler — no strict no-wash window and no special sulphate rules in the first days.
Which one is right for you?
Choose nanoplasty if you want months of sleek, low-maintenance, frizz-free hair without formaldehyde. If you love your waves and just want frizz control, consider Wella SmoothFiller instead — it smooths while preserving your natural texture. And for permanently poker-straight hair, Shiseido Japanese straightening restructures the hair permanently. At Hair Avenue we offer all three, so a free consultation will land you on the right one for your hair type, routine and budget. Nanoplasty starts from $384.
