People with fine, thin, or limp hair that lacks natural volume and falls flat during the day. Suitable for color-treated hair since the paraben-free formula won't strip color. Not intended to add texture or hold for thick or coarse hair types, which don't typically need volumizing support.

Its differentiator is being purpose-built for fine hair specifically rather than marketed as universally suitable — the film-forming polymer blend targets the 'flat by midday' problem fine hair has, rather than functioning as a generic styling spray relabeled as a volumizer.

1. Shake well before use.
2. Spray from roots to ends on clean, damp hair.
3. Do not rinse out.
4. Style as usual; pair with Biolage VolumeBloom Shampoo and Conditioner for the fuller advertised effect.

Pros:

• Formulated specifically for fine/flat hair rather than marketed as a generic all-hair-types volumizer
• Leave-in spray applies quickly to damp hair before styling
• Paraben-free and labeled safe for color-treated hair
• Lightweight, polymer-based formula designed not to weigh hair down

Cons:

• The advertised '70% more volume' figure applies to the full VolumeBloom shampoo-and-conditioner system, not the spray used alone
• Contains multiple fragrance allergens (linalool, coumarin, hexyl cinnamal, and others)
• Not intended for thick or coarse hair, which doesn't need this kind of lift
