Silicones seal the skin and hair. Their extreme creepability allows them to penetrate particularly deeply into the hair and makes them difficult or impossible to rinse out. Silicones can be identified by endings such as ‘con(e)’, ‘ol’ or ‘oxan(e)’. Because they are also difficult to break down and harmful to the environment, you should choose natural products.
