Living Proof Style Lab Flex Hairspray — Flexible, Brushable Hold, Humidity-Resistant Finish (7 oz)

Living Proof Style Lab Flex Hairspray delivers a flexible, brushable hold that builds structure, finishes styles, and resists humidity without flaking or visible residue.

Designed for everyday styling, this versatile hairspray works on damp or dry hair to shape, set, or refine looks while preserving natural movement and shine. It provides enough grip to support structured styles when applied to wet hair, and a light, finishable hold when misted on dry hair. The formula layers easily, can be restyled without stiffness, and leaves hair looking polished rather than coated.

How should I use Flex to build and shape styles?

Apply Flex to towel-damped hair to create structure and support during the styling process. Spray from a short distance while molding sections with your hands or tools; the product helps hair hold shape as it dries so your style lasts longer without feeling crunchy.

• Spray on damp hair before blow-drying to add body and workable hold
• Use while sculpting with a round brush or fingers for defined shapes
• Layer as needed—formula is brushable and won’t cause buildup

Can I use this hairspray to finish a style on dry hair?

Yes — a light mist of Flex on dry hair provides flexible hold and natural movement while adding glossy shine. It tames flyaways and offers humidity protection without flaking, so your finishing touch looks smooth and polished all day.

• Spray lightly to set curls or tame frizz without stiffening
• Use a closer spray for targeted control, or wider for overall sheen
• Reworkable formula allows touch-ups without sticky residue

Will this product build up or make hair feel stiff over time?

Flex is formulated to be brushable and layerable, so it won’t leave stiff, crunchy buildup with normal use. You can restyle throughout the day and remove product with routine cleansing without a heavy residue left behind.

• Brushable texture means styles can be softened after setting
• Layering won’t weigh hair down when applied as directed
• Removes with regular shampooing—no long-term coating

How does Flex perform in humid or active conditions?

Flex provides humidity protection that helps hair retain shape and resist frizz in damp or humid environments. It balances hold with movement so hair remains touchable and natural-looking even when moisture levels rise.

• Designed to reduce humidity-related frizz and loss of shape
• Maintains a soft, flexible finish rather than a hard shell
• Suitable for daily wear and active, on-the-go schedules

Who is this for: Living Proof Style Lab Flex Hairspray is ideal for anyone who wants a reliable, flexible finish—styling professionals and everyday users alike. It’s especially useful for people who need buildable structure when styling from damp hair, a natural-feeling finish on dry hair, or a humidity-resistant product that won’t flake or leave visible residue. If you prefer touchable styles that can be reshaped during the day, Flex delivers workable hold without stiffness.
