R+Co DALLAS Biotin Thickening Shampoo — 8.5 fl oz, Dark Waves scent | Volumizing, Sulfate-Free

R+Co DALLAS Biotin Thickening Shampoo is a volumizing daily shampoo formulated with biotin, coconut oil, and loquat extract to add immediate body, strength, and shine to fine or flat hair.

This salon-inspired formula targets limp hair by improving texture and lift from root to tip without sulfates, parabens, or gluten. Designed by a collective of stylists, the DALLAS shampoo layers thermal and UV protection into a lightweight, conditioning blend that helps hair look fuller while preserving natural movement. The scent, Dark Waves, gives a modern, warm aromatic finish suited to everyday use.

How does DALLAS create noticeable volume without weighing hair down?

The formula combines biotin to support the hair’s keratin network with conditioning emollients that avoid heavy residue. Instead of coating strands with heavy oils, it uses lighter botanicals and surfactants to lift roots and enhance body while maintaining softness.

• Biotin supports strand structure for fuller appearance
• Coconut oil and loquat extract add moisture without heaviness
• Sulfate-free cleansing preserves natural lift and prevents flattening
• Light conditioning agents enhance movement and detangling

What results can I expect after using DALLAS regularly?

With consistent use, hair looks thicker and feels stronger, with improved manageability and bounce. Texture becomes more defined at the root, making styling easier while reducing the need for heavy styling products that compromise volume.

• Improved fullness and body after a few washes
• Reduced breakage from strengthened keratin structure
• Smoother, more resilient strands that hold style better
• Noticeable lift at the roots for airy hairstyles

How should I use the shampoo for best effect?

Apply the shampoo to wet hair, massaging the scalp to distribute the formula and stimulate circulation, then work the lather gently through to ends before rinsing. For maximum volumizing benefit, follow with a lightweight R+Co conditioner or styling product and style while damp to lock in lift.

• Wet hair thoroughly before applying a coin-sized amount
• Massage into scalp for 30–60 seconds, then comb through to ends
• Rinse well and repeat if hair is very oily or product-heavy
• Pair with volumizing conditioners or root-lifting creams
