We're breaking down the new product and how it builds into a Dallas-led haircare routine on the whole so you can scoop up your most-needed product or dive into the full family to bring life back to limp hair. Saddle up! Here's how to build your biggest hair yet with the Dallas collection.

Biotin Thickening Shampoo

Your baseline for volume starts with a good shampoo. This one's going to add vitality to fine, flat hair and strengthen from root to tip for less breakage and a thicker look overall.

Biotin Thickening Conditioner

Not all conditioners are created equal, especially if you're concerned about weighing your hair down. This pick builds volume and adds lightweight hydration that keeps strands bouncy.

Biotin Thickening Treatment

Think of this treatment as a weekly turbo-boost to turn flat hair on its head. Use in place of your conditioner for body-boosting results and major frizz control that lasts up to 10 washes.

Biotin Thickening Spray

A no-brainer to amplify your blow-dry, this root-volumizing formula works on damp hair to lift each strand as you style for a sky-high finishing look.
