How to properly choose your conditioner?

Applied after shampooing, this treatment, also referred to as a conditioner in English, helps to smooth the cuticles of the hair, separate them from each other, and untangle knots. It is generally chosen based on one's hair type and its composition. We help you see more clearly in this article!

Selection Criterion #1: Your hair type.

The first criterion for choosing a conditioner is to adapt it according to your hair type. While some are solely designed to detangle the hair, others may contain active ingredients, like a hair mask. There are different types of conditioners for each hair type.

  • Straight and flat hair

To care for this type of hair, it is appropriate to use a conditioner that strengthens and coats the hair fiber to provide structure and volume to the hair. We recommend you to favor natural ingredients to care for the hair without damaging it, but to avoid overly rich fatty substances like certain vegetable oils (coconut, castor, avocado...), which can weigh it down. Thus, favor active ingredients like plant proteins, such as vegetable keratin, hydrating compounds (aloe vera gel, hyaluronic acid...), vitamins (B8, provitamin B5...).

  • Curly to even kinky hair

This type of hair has the characteristic of being naturally dry. Conditioners designed for curly hair often come in the form of thick and rich creams. This type of conditioner will tone and define your hair's curls. Opt for treatments enriched with plant-based fatty substances such as mango butter, shea butter, avocado oil, or argan oil.

  • Oily Hair

Oily hair is often a misnomer; in fact, it's a greasy scalp that produces excess sebum, which slides down the hair shafts, giving the hair a sometimes unattractive shiny appearance. The conditioner for oily hair should be enriched with absorbent agents capable of absorbing impurities and fats. These include mineral powders such as green clay (I.N.C.I.: Montmorillonite) or white clay (I.N.C.I.: Kaolin / Montmorillonite) whose layered structures, known as "lamellar", allow for the absorption of lipids. Some masks can also be enriched with Moroccan rhassoul (or ghassoul). Known as the "cleansing earth", this volcanic clay acts like an absorbent filter that will purify the hair.

Note: No matter what type of hair one has, the conditioner should always be applied after shampooing. It should be spread over the ends and lengths of the hair. If applied to the scalp, it may weigh down the hair and give it a greasy appearance.

Selection Criterion #2: The Ingredient List

In order not to harm your hair, favor a conditioner enriched with natural and/or organic ingredients. You can refer to the naturality index sometimes listed on the product in question or to a biological certification.

Note! Conditioner can come in two forms: liquid and solid. It is the ingredients of liquid conditioners that need to be checked. Solid conditioners are often of natural and ecological origin.

There are certain categories of ingredients to avoid in conditioners as they can damage the quality of your hair or be harmful to the planet.

  • Parabens

    Used as preservatives, parabens are potential endocrine disruptors (= substances that can interfere with hormonal balance). Since 2014, the use of certain parabens has been prohibited in cosmetics.Among the ingredients, they can be easily identified by their I.N.C.I. name, which typically ends with paraben (Butylparaben, Propylparaben...). For your information, organic hair care products do not contain parabens.

  • Silicones

    Silicones are synthetic ingredients that have been used since the 1970s. Originally, they were chosen to replace petroleum substitutes like paraffin in cosmetic products. Their sensory qualities, which are hard to match, have made them widely used ingredients in the cosmetic market.However, for several years now, they have been under scrutiny due to their environmental impact, and some are suspected of being harmful to health.

    Regarding their presence in certain conditioners,silicones should be avoided as they areocclusive compounds. In the short term, they prevent the active ingredients in hair care products from penetrating the hair fiber. In the long term, they weigh down and grease the hair. To identify them among the ingredients, their I.N.C.I. name ends with -icone, -iconol, or -xane, such as phenyl trimethicone, polysiloxane, etc.

  • Sulfates

    Tensio-actives are responsible for removing oil from the hair. Sulfates are stripping agents and can damage the hair fiber. They also have a drying effect on the hair. Not being a cleansing treatment, not all conditioners necessarily contain sulfates. These can be identified in the list of ingredients under the names sodium lauryl sulfate or ammonium lauryl sulfate.

    Not all sulfates are harsh. It all depends on how they were derived. While it's advisable to avoid sulfates that come from a chemical base, you can freely use those derived from a plant base such as coconut or sugar.
