- Wash the hair with the Nature Eva Home Care line.
- Dry the hair.
Please note:
- When you rinse the hair it is normal for it to still feel slightly sticky as the product is never completely removed. It is only when the heat is applied from the straightener that the product evaporates and leaves the hair shiny and smooth.
- The treatment lasts between 6-9 months, although the exact time frame will vary from person to person.
- We highly recommend Nature Eva Argan Shampoo and Cream (maintenance kit) for a long-lasting effect.
- You can still style or curl the hair and once it is washed it will return to being straight.

Frequently question about Nature Eva
Nanoplastia is a professional hair straightening treatment that uses nanotechnology and amino acids to restructure the hair fibre from within. Unlike keratin treatments, it is 100% formaldehyde-free, with no harsh fumes or scalp irritation. While keratin coats the outside of the strand, nanoplastia penetrates deep into the hair cortex to repair, reconstruct and align each fibre, delivering smoother, shinier and healthier results that last significantly longer.
When applied correctly by a trained professional, results can last between four and eight months, depending on the client's hair type and aftercare routine. Coarser, curlier hair may require more frequent applications, whilst finer or wavy hair tends to retain results for longer. Using sulphate-free homecare products significantly extends the longevity of the treatment.
