What is the role of conditioner?

Conditioner: What is its usefulness?

Designed to focus on the lengths and ends, theconditioner is a hair care product with a coating texture that has been technically developed to temporarily seal split ends, give the illusion of thick hair, and enhance the feel, appearance, volume, shine, and overall manageability of hair. The concept of conditioner was first created specifically for men by a perfumer named Edouard. He wanted to develop a formula intended to soften mustaches and beards. The conditioner, which has continued to evolve since, now offers numerous benefits to keep hair shiny and soft.

Contrary to popular belief, short hair also requires conditioner, albeit less frequently than long hair.

Benefit #1: The conditioner improves the texture of the hair.

Hair that has just been washed can be dry, dull, and difficult to style. Split ends occur when the protective cuticle of the distal hair shaft and the exposed cortex separate. Indeed, most shampoos have an alkaline pH, which causes the hair shaft to swell. This swelling loosens the protective cuticle, predisposing the hair shaft to damage. The use of a conditioner flattens the cuticle scales on the hair shaft thanks to cationic surfactants. They are excellent for increasing the adherence of the cuticular scales to the hair shaft, which enhances the hair's light-reflecting capabilities, adding shine and luster, and also reduces friction between hair fibers.

Benefit #2: The conditioner restores the protective film.

During the hair washing process, the lipid layer that envelops the hair fibers is removed by the shampoo. This layer is responsible for the hair's hydrophobicity, and its removal can damage the hair by making the fiber hydrophilic. Thanks to conditioning substances (silicones, vegetable oils, propylene glycol, etc.), the conditioner will help to cover the hair shafts with a protective layer to restore the fiber's hydrophobicity. It thus contributes to restoring hair shine by reflecting light, and to protecting it against damage and split ends.

Benefit #3: The conditioner to facilitate detangling.

Its application on the hair fiber will limit the formation of knots and facilitate styling. It is particularly beneficial for wavy, curly, or even kinky hair that tends to frizz. The conditioner is capable of neutralizing static electricity due to the negative charge (anionic) of treated or damaged hair, which attracts the positive charge (cationic) to adhere to the hair shaft, thereby improving its manageability in both wet and dry conditions.

Our resurfacing conditioner is suitable for all hair types.
