This spray is aimed at people with fine or medium-density hair who lose volume by midday or whose hair falls flat at the roots. It suits any hair length, since it can be targeted at the roots alone for lift or run through the lengths for texture. Because it depends on heat to activate the volumizing polymers, it's best for people who blow-dry their hair regularly rather than those who air-dry, and it's a consumer retail styling product rather than a professional backbar treatment, even though TIGI markets the Bed Head line through salons as well as retail.

The distinguishing feature here is the heat-activation: rather than just coating hair with a stiff polymer film the moment you spray it, the formula is designed to set its volume and texture as you blow-dry, so results build in as part of your normal drying routine instead of requiring a separate step. Combined with the option to spray only at the roots versus through the ends, it gives more targeted control over where the volume shows up than a generic all-over volumizing spray.

Shake the can before use. Spray onto towel-dried, damp hair from about 8-10 inches away, working from roots to ends and between sections. Apply at the roots for lift, or through the mid-lengths and ends for added texture, then blow-dry to activate the volumizing effect.

Pros:

• Heat-activated formula is built to work with blow-drying specifically, so volume builds as hair is dried rather than relying on the spray alone
• Can be targeted: root application for lift versus mid-length-to-ends application for texture, giving more control than an all-over spray
• Film-forming polymers add hold without the stiff, stuck-together feel of a stronger-hold finishing hairspray

Cons:

• It's an aerosol can using hydrofluorocarbon/dimethyl ether propellant, not a pump spray, which some people prefer to avoid
• Formulated specifically for fine-to-medium hair; it is not positioned for coarse, thick, or very curly hair textures needing heavier hold
• Contains parabens and multiple fragrance-allergen ingredients (geraniol, limonene, linalool, citral, and others), which matters for anyone specifically avoiding those
