What is a Hair Serum?
Think of a hair serum as the secret weapon in your beauty arsenal, much like your favorite face serum. Just as you apply a serum after cleansing your skin to enhance your skincare routine, a hair serum provides that extra layer of protection and nourishment for your strands. Hair serums shield your locks from environmental damage like heat, pollution, and UV rays, helping to keep your hair healthy and vibrant. Whether you’re dealing with dryness, frizz, or dullness, there’s a Kérastase serum ready to help you achieve your hair goals.
