About this product

A leave-in hair lightening spray for blonde hair that uses hydrogen peroxide to gradually lift color and add brightness. The formula includes conditioning polymers and panthenol, but it also carries fragrance and a meaningful risk of dryness, breakage, and scalp irritation if overused or used on unsuitable hair shades.

Good signs
  • Provides gradual lightening rather than an immediate harsh bleach effect.
  • Includes conditioning and film-forming ingredients that can help with manageability and softness.
  • Silicone-free and marketed for use with heat styling.
  • Suitable for natural and color-treated blondes when used as directed.
Watch-outs
  • Contains hydrogen peroxide, so it can be drying and should be used cautiously on fragile or previously processed hair.
  • Contains fragrance plus citrus-derived scent components, which may bother sensitive scalps.
  • Not a good fit for darker hair, heavily bleached hair, or irritated scalp skin.
  • Lightening results can be uneven, especially with spray application.
Best for
  • Natural or color-treated blondes seeking subtle, gradual brightening.
  • Users wanting a leave-in lightening step rather than an all-over bleach service.
  • Hair that can tolerate peroxide-based cosmetic lightening.
How to use it
  • Apply to clean, towel-dried hair and style with heat for stronger lightening.
  • Limit use to the directions on pack and avoid sensitive or damaged scalp skin.
  • Do not use on brown or darker shades, platinum or white blonde, or heavily bleached hair.
  • Protect clothing and fabrics from overspray.
