3 ingredients to avoid in your shampoos and hair care

Certain components attack the fiber and / or pollute the planet. Rodophe Diotel, founder of the Rodolphe & Co brand, lists the main ones and deciphers them for us.

We are talking more and more about “clean” cosmetic formulas, that is to say free of ingredients harmful to our health and the planet. Here are a few that are often found in hair products.


They are derived from petrochemicals. Used for their immediate shining effect on the fiber, they weigh down the hair and suffocate the scalp. Hair quickly becomes greasy after using a product containing silicones.

They are pollutants for the planet. Their names are dimethicone or cyclopentasiloxane and therefore generally end with -one and -oxane.


Used in shampoos as foaming agents, they tend to irritating the skin and being too cleanser for the scalp. Their name contains the word “sulfate” (sodium laureth sulfate, ammonium lauryl sulfate…).

There are surfactants made from coconut and sugar that are much milder and just as effective.

Some preservatives

The phenoxyethanol, the Happy birthday, the methylisothiazolinone (or MIT) are often used to store hair products. The first two are known to be endocrine disruptors (they can unnecessarily stimulate hormone receptors). The latter is allergenic and may irritate the skin. It can cause itching, eczema, or other dermatitis.
