Best suited to fine hair that falls flat easily and needs help holding volume through a blow-dry and through the day; also works on normal and coarse textures that want a lightweight styling boost rather than a stiff hold.

Suitable for short, medium, or long hair, and for either home or in-salon use — there's no professional-only application step here.

The appeal of Naturally Full is that it removes the guesswork from building volume on fine hair: the same product primes towel-dried roots before blow-drying and then finishes dry lengths, so there's no need to layer a separate root lifter and hairspray. Because the hold is polymer-based rather than wax- or resin-heavy, it brushes out cleanly instead of leaving hair stiff, which matters most for people whose hair is fine enough that heavier stylers weigh it down.

Use on towel-dried hair before blow-drying, and again on dry hair to finish.

• Spray onto damp, towel-dried roots and blow-dry as usual to build lift and volume.
• On dry hair, mist lightly through mid-lengths and ends to add texture and set the style.
• Reapply sparingly through the day to refresh volume without adding stiffness.

Pros

• Lightweight, non-sticky finish that adds fullness without a stiff or crunchy feel, well suited to fine hair that falls flat easily.
• Doubles as both a blow-dry primer and a finishing spray, cutting a step out of a volumizing routine.
• Includes a UV filter and heat-protective polymer that help limit color fade and thermal damage during blow-drying and styling.

Cons

• Contains alcohol denat. and isopropyl alcohol, which can be drying to the hair shaft with very frequent use, particularly on porous or chemically treated hair.
• Factor-3 hold is moderate rather than maximum, so it won't hold intricate updos or resist heavy humidity the way a stronger-hold hairspray would.
• The aerosol packaging relies on hydrocarbon propellants, which some people prefer to avoid.
