Bumble and bumble. Thickening Blow‑Dry Prep Spray — 8.5 fl oz, lightweight volume & root lift for fine to medium hair

This prep spray from Bumble and bumble is formulated to add lift and body before you step up to the blow dryer. Designed for fine to medium straight and wavy hair, it lays down a foundation of texture and root lift without weighing hair down or leaving sticky residue. Use it as the first step in your styling routine to help brushes and hot tools shape hair more easily and lock in a visibly fuller-looking finish.

How does this spray transform limp or flat hair?

The formula deposits lightweight polymers that cling to individual strands, creating more diameter and grip so hair holds style better. Applied at the roots and along mid-lengths, it gives your brush something to lift and your blow dryer something to amplify.

• Spray onto towel-dried hair for immediate texture and root lift.
• Provides buildable thickness without stiffness or heaviness.
• Helps hair maintain volume throughout the day when paired with heat styling.

When should I apply the Thickening Blow‑Dry Prep Spray?

Use it right after cleansing and after towel-drying — before any styling cream, serum, or heat tool. It’s a primer for blowouts, so applying to damp hair ensures the ingredients distribute evenly and activate with heat for best results.

• Apply to damp hair, focusing on roots for lift and mid-lengths for body.
• Comb or rake through to spread product evenly for uniform thickness.
• Blow-dry with a round brush or diffuser to lock in volume.

Will this product weigh my hair down or make it sticky?

No — the spray is formulated to remain light while building texture, so it won’t leave a heavy film or tacky residue. Users with fine to medium hair often find it creates natural movement and separation rather than stiffness.

• Non-greasy finish preserves natural movement and shine.
• Layerable formula works under other styling products without buildup.
• Rinses out easily during shampooing if you want a fresh start.

What does it smell like and who will benefit most?

The scent features sparkling cassis top notes, watery cyclamen heart notes, and a mint leaf base for a fresh, slightly fruity aroma during styling. It’s tailored for people with fine to medium straight or wavy hair seeking easier blow-drying, long-lasting lift, and a fuller appearance.

• Fragrance profile: cassis, cyclamen, mint leaf — fresh and subtle.
• Best for straight to wavy textures that need extra volume.
• Salon pros use it as a go-to pre-styling primer for blowouts.

Who is this for? If your hair tends to lie flat at the roots or looks thin when air-dried, Bumble and bumble Thickening Blow‑Dry Prep Spray is made to help you achieve a fuller, salon-style blowout with minimal effort. It’s ideal for anyone who wants lightweight, buildable thickness and improved manageability before using brushes and heat tools.
