Perfect for my hair
[This review was collected as part of a promotion.] I love how easy this heat protectant is to use! The pump makes it convenient to dispense, so I highly recommend for someone who bleaches their hair like me. I’m always looking for products to help protect my hair, and this is perfect for that.

[This review was collected as part of a promotion.] For the first time ever, my hair has volume and bounce! Thanks to this K18 Heat Bounce, conditioning heat protectant. I love that this can protect hair up to 450°F, and can be used on towel dried hair before blow drying and on dry hair before hot tools.
