Why hair cuticles open

And how keraricostructive products repair them

Hair health begins with the cuticle, the outermost layer of the hair fiber that functions as a natural shield. When the cuticle is closed and compact, hair appears smooth, shiny and soft. In contrast, when they open or flake, the hair becomes dull, brittle and prone to breakage.

Why do hair cuticles open?

The main causes are related to chemical and environmental stresses

• aggressive treatments such as dyeing, bleaching or straightening

• frequent use of hair dryers and straighteners at high temperatures

• exposure to smog, sun and humidity

• lack of hydration and nutrients

Under these conditions, the cuticle lifts, the fiber loses firmness and the hair feels dull and rough to the touch...So how to do it?

How keraricostructive products work

Napura's Rikeir line is the one dedicated to keraricostructive treatments.

The main ingredients we find within the formulas are:

Wheat, Rice and AlmondProteins, which have a repairing and strengthening action: they bind to the hair's natural keratin, filling the fiber's micro-fractures and making it stronger and more elastic.

Avocado and Jojoba Oils, on the other hand, have an emollient and nourishing effect: they help seal the cuticles, creating a protective film that retains moisture and protects against future damage.
