We recommend applying and leaving in Hotheads Smooth Conditioner prior to swimming. This nourishes the hair and allows it to absorb the moisture. This prevents the hair from absorbing harmful elements, such as chlorine and minerals. Hair tangles when dirt and sweat build up so advise clients to wear their hair up or in a ponytail when exercising or relaxing in a sauna. They must be sure to wash their hair after working out, as well as brushing before and after exercising.  Exposing extensions to sunscreen may cause discoloration.
