Summer is here and it is hot outside! One great benefit of the temperature heating up outside is most people cool down the temperature during showers. Cooler showers or rinsing hair in colder water helps add shine to hair. Exactly how we close our pores to improve our skins overall look our hair shaft shares the same principle. It has a cuticle that when rinsed with cooler water is able to close, like your pores do, and offer a more radiant appearance. So keep it cool when it comes to rinsing your hair to stay shiny all year long.
