Bumble and Bumble - Thickening Spray

Apply the Thickening Spray to freshly washed, towel-dried hair before blow-drying. Distribute the product evenly from roots to ends, then style as usual with a round brush or diffuser for maximum volume and body.

The spray features three hero ingredients that work together during blow-drying:

• Hydrolysed wheat protein – strengthens each strand and adds resilience.
• Honey – nourishes and helps retain moisture for a healthy finish.
• Lanolin – conditions and smooths the hair for added shine and softness.

Yes, the Thickening Spray is safe for colour-treated hair. The formula is free from parabens, phthalates, mineral oil, sulphates (SLS/SLES) and formaldehyde — ingredients that can strip or fade colour — making it a gentle choice for chemically treated or highlighted hair.

The Thickening Spray is lightweight enough for daily use. Because it does not contain heavy silicones or weighing-down ingredients, it will not cause build-up, so you can use it every time you blow-dry your hair without compromising volume or movement.

After just one use, you can expect visibly fuller, bouncier hair with enhanced body and shine. The Strand-Plumping Technology thickens each individual strand from root to tip, delivering a long-lasting, voluminous blow-dry without stiffness or heaviness.
