For styles that need to hold hard: updos, sleek ponytails, bridal and event hair, and set curls that have to survive humidity. It suits all hair types, including thick or heavy hair that drops a style quickly, and is a common salon finishing spray. It's more hold than most people need for a casual everyday look.

Power Spray is the one to reach for when a style simply cannot fall: it dries fast, holds at an 8+ level, and keeps humidity out for up to 72 hours, while also protecting against heat, UV and pollution. Being able to build from strong to ultra-firm hold with extra layers means one can covers everything from a sleek ponytail to a wedding updo.

Shake well. Spray 8 to 10 inches (20 to 30 cm) from dry hair over the finished style, smoothing strands as you go. Layer additional passes for stronger to ultra-firm hold.

Pros:

• Ultra-firm, fast-drying hold that Joico rates for up to 72 hours of humidity protection
• Buildable: one light pass for strong hold, more layers for ultra-firm
• Thermal protection up to 232°C (450°F) plus UVA/UVB and pollution protection
• Clear finish without flaking

Cons:

• Too firm for a soft, touchable everyday finish
• Layered heavily, it can make hair feel set rather than movable
• Aerosol, so keep it away from heat and flame
