R+Co Biotin Thickening Shampoo & Conditioner Set 2×8.5 oz — Sulfate-Free, Vegan Volume for Fine Hair

R+Co Dallas Biotin Thickening Shampoo and Conditioner Set is a sulfate-free, vegan duo formulated with biotin to add immediate lift, body, and visible thickness to fine or thinning hair.

This two-piece kit pairs a lightweight, fortifying shampoo with a moisturizing yet non-weighty conditioner to create fuller-looking hair without residue. The formulas are free of sulfates and parabens, cruelty-free and vegan, and carry R+Co’s Dark Waves scent — a warm mix of cardamom, pineapple, tangerine, and lavender. Use this set together to strengthen strands, improve manageability, and support a round, lifted style from root to tip.

How quickly will I see more volume after using the Dallas duo?

Most users notice increased lift and a fuller appearance after their first wash because the shampoo cleanses without stripping and the conditioner layers lightweight body. Results build with regular use as biotin-targeted ingredients help improve strand resilience and reduce the look of breakage over time.

• Instant visible lift at the roots after rinsing and styling
• Progressive thickening effect with consistent use
• Lightweight conditioning prevents flattening between washes

Will this set work on chemically treated or colored hair?

The sulfate-free formulas are designed to be gentle on color-treated and chemically processed hair while still providing cleansing and body. Because the conditioner is weightless, it helps preserve style and shine without dragging color down.

• Sulfate-free cleansing reduces color fade compared with harsher shampoos
• Biotin and fortifying agents support weakened strands from chemical services
• Safe for routine use on highlighted, colored, or relaxed hair types

How should I use each product to maximize thickness and manageability?

Apply the shampoo to wet hair, gently massage into the scalp to lift at the roots, then rinse thoroughly. Follow with conditioner applied mainly to mid-lengths and ends, leave on for 1–2 minutes, then rinse for best volume and softness.

• Shampoo: massage into scalp for targeted lift, then rinse
• Conditioner: avoid heavy application at roots; focus on lengths and ends
• Rinse and style as usual to preserve natural body and movement

What can I expect from the scent and formulation ingredients?

The scent is Dark Waves, a sophisticated blend of spicy cardamom, bright pineapple and tangerine, with a calm lavender base for an approachable, luxe aroma. Formulation highlights include biotin for fortification and lightweight emollients that hydrate without weighing hair down.

• Dark Waves fragrance: warm, fruity-spicy profile for salon-fresh hair
• Biotin-infused to support stronger-looking strands
• Vegan, cruelty-free, and free of sulfates and parabens
