Alterna is another brand that I really like, but when it came out with its Caviar Anti-Aging Working Hair Spray ($26) and the rest of its Anti-Aging line, a little part of me rebelled. Hair products can be more or less emollient and moisturizing, but as far as anti-aging . . . well, your hair is already dead, so bringing it back to life and making it somehow "younger" would be quite the feat.
