What is the best way to protect your hair from the sun and wind?

Serum is your secret ally for shiny and healthy hair. The role of hair serum is to protect it from external factors. Serums typically contain ingredients such as keratin or argan oil in their formula. They penetrate deep into the hair to moisturize and renew it. If you incorporate a serum into your hair care routine, your hair will always be protected, strong, and hydrated.
