After washing and towel-drying your hair, apply a small amount of L'Oréal Frizz Killer Serum to your damp hair.
Distribute evenly through your hair, focusing on the mid-lengths to ends.
Style your hair as usual, using a blow dryer, straightener, or leaving it natural.
For extra smoothness, you can also apply a small amount to dry hair to tame flyaways throughout the day.
