Silicones in hair care: harmful or not

What silicones are and why they are used

Silicones are a large group of ingredients; in ingredient lists they often end in “-icone” or “-siloxane”: Dimethicone, Amodimethicone, Cyclopentasiloxane and so on. They form a thin smooth layer on the strand surface, so hair tangles less, combs more easily, shines and frizzes less.

Different silicones work differently: Amodimethicone settles more on damaged areas of the lengths; Cyclopentasiloxane is light and evaporates, helping an oil or cream spread evenly.

Are silicones harmful

Silicones are permitted and widely used cosmetic ingredients. They don’t “suffocate” hair: the strand is not living tissue that needs to “breathe”.

The real issue is weight: if there are too many leave-ins and too little cleansing, fine hair can look heavy and lose freshness faster. It is a matter of amount and matching, not of silicones being “harmful”.

How to avoid build-up

• apply balsam, mask and leave-ins to the lengths only, not the roots;
• use oil a few drops at a time, starting with the minimum;
• rinse shampoo, balsam and mask thoroughly;
• if hair is fine and gets heavy quickly — choose the lighter Intensive Care system and use masks on schedule, not every time.
