Look, if you're spending any time in the pool or at the beach, you need the Swimcap Water-Resistant Hair Mask. Philip Kingsley originally made this stuff for Olympic swimmers, so you know it's legit. It basically creates a shield around your hair so chlorine, salt water, and sun damage can't totally wreck it.Here's what's cool about it – it keeps your hair hydrated and shiny even when you're putting it through hell. If you've got color-treated hair, it'll stop that weird greenish tint that pool water loves to cause. The formula's loaded with good stuff like Olive Oil and Castor Seed Oil that actually feed your hair, plus this ingredient called Hydrolyzed Elastin that keeps your hair bouncy and full of life instead of limp and sad.It works for any hair type and smells pretty nice without being overpowering. Just slap it on before you hit the water or go lay out in the sun, and you're good to go. Your hair will thank you later.
