Frequently Asked Questions

What is the fragrance?

Natura Lumina has authorial and sophisticated fragrances. Rescuing the historical olfactive signature of Natura in Hair Care, it’s in the aromatic olfactive family, with a vegetable green irreverence combined with floral femininity and refreshing citrus, reinforcing the performance and connection between science and nature of these products.

The olfactive signature was adapted to each treatment system of this product line to enhance the benefits for each type of hair: Fruity touches of cassis and apple with the femininity of the floral bouquet of Rose and Jasmin, and with the vegetable green olfactive signature, enhance hair hydration and definition.

For curly hair, the curl tends to be dry and brittle, especially at the ends, with frizz and excessive volume.

Improved shine and frizz control, intense hydration for 24 hours long-lasting curl definition. Hair detangling from the first wash. Well defined shiny hair, no frizz, healthy hair from the first application.

We identified that the spider web protein and hair protein have the same design, revealing a unique similarity between them. Then, it can connect with the hair and promote a protein repair, with a specific focus on each damaged area of the hair fiber.

We reproduced the web protein in the laboratory and then we created a new advanced technology for hair treatment: Pro-web Biotechnology. This protein acts deeper, truly filling the hair fiber, from the inside out. And it is a smart filling, according to the hair damage. Neither more nor less.

The results? Healthy hair since the first application. Precision hair treatment, that is, it repairs different levels of strand damaged, treating each damaged differently. Truly regenerated hair. No tricks.
