Keune Care Absolute Volume Thermal Protector Spray protects hair from thermal and heat styling tools. Big is beautiful – especially when hair is concerned. If you’ve got normal to fine hair and want more volume and thickness, our Absolute Volume range is perfect for you. It’s enriched with Provitamin B5. This vitamin penetrates deeply into the hair shaft, where it thickens the inner structure, strengthening and nourishing it from the inside out. Your hair will be noticeably more voluminous and full, without feeling heavy. Like its name says, this spray protects hair from thermal and heat styling tools like flatirons, curling irons and blow dryers. Added proteins ensure a flexible hold.
