Key takeaways
- Keratin smoothing is a commercial name for chemical hair smoothing, the same family as Nanoplastia.
- The finish is a choice: 100% straight, natural anti-frizz or curl definition.
- Results last 3 to 6 months with full processing time (40–60 min) and correct sealing.
What is a keratin smoothing treatment? It is a professional chemical smoothing service that reduces volume and frizz and can straighten the hair completely. The active works in the cortex and the cuticle and is sealed with a flat iron. Done correctly, it delivers a 100% straight or natural anti-frizz finish that lasts 3 to 6 months.
Keratin, protein, botox, Brazilian blowout and Nanoplastia are commercial names for one family: chemical hair smoothing. A Nanoplastia with hydrolysed keratin is also a keratin treatment; with hydrolysed proteins it is also a protein treatment. What really separates services is the smoothing active and the quality of the raw materials.
