Mousse contains polymers that hold hair in position. These polymers can accumulate and leave your hair feeling sticky or brittle if you use too much mousse.
The application of an excessive quantity of mousse can make it difficult to style your hair. The excess product can make your hair more difficult to manipulate.
Excessive mousse use can result in product accumulation on the hair and scalp. This can cause your hair to appear drab and lifeless.
