Living Proof Style Lab Flex Hairspray — Medium-hold, brushable finish and heat protection to 410°F

Living Proof Style Lab Flex Hairspray is a medium-hold finishing spray that sets and sculpts hair while remaining touchable, brushable, and heat-protective.

Designed for everyday styling, this flexible hairspray gives control without the crunchy residue common to stronger lacquers. It works on damp or dry hair to lock in shape, allow layering, and let you restyle during the day. The formula also offers heat-shield protection up to 410°F (210°C), so you can use hot tools with added reassurance.

How does this hairspray behave on damp versus dry hair?

The product is formulated to perform on both wet and dry hair, so you can use it during the styling process or as a final finish. Spraying on damp hair helps set waves and hold shape when you blow-dry, while applying to dry hair offers instant hold and polish without stiffness. Either approach keeps strands flexible and reworkable.

• Use on damp hair to set blowouts, waves, or heat-styled shapes.
• Spray on dry hair to tame flyaways and add a soft hold.
• Remains brushable so you can blend or soften the finish.

Will it make my hair feel stiff or sticky?

No — the Style Lab Flex formula prioritizes a natural, touchable finish. It secures styles but avoids the brittle, lacquered texture of extreme-hold sprays, so hair moves and feels softer to the touch. That makes it ideal when you want hold without sacrificing a natural look.

• Medium hold keeps styles intact without locking them in place.
• Brushable finish lets you soften or restyle without buildup.
• Leaves minimal residue, maintaining natural movement.

Can I use this with heat tools, and what protection does it provide?

Yes — the hairspray offers thermal shielding up to 410°F (210°C), so it complements heat styling. Apply prior to or after using a flat iron or curling iron to add a protective layer that helps minimize heat stress. It’s not a replacement for dedicated heat protectants on damaged hair, but it adds a useful barrier during regular styling.

• Heat shield rated to 410°F / 210°C for routine hot-tool use.
• Compatible with blow-dryers, irons, and wands when used as directed.
• Helps preserve style shape while offering extra surface protection.

How can I layer or restyle hair when using this spray?

The formula supports layering and easy manipulation, so you can build hold or refresh sections throughout the day. Because the finish remains workable, you can brush through to soften or add another mist to increase hold without flaking. This makes it a versatile choice for multi-step styling routines.

• Layer multiple light sprays instead of one heavy application for tailored hold.
• Brush through to reshape or soften the effect without residue.
• Ideal for touch-ups that require quick restyling without a full redo.

Who this product is for: If you want a dependable, medium-hold hairspray that preserves natural movement, supports layering, and adds heat protection, this is a practical option. It suits people who dislike stiff finishes but still need reliable staying power — from daily commuters to stylists doing touch-ups. Use it when you want controlled shape with a soft, brushable result.
