R+Co Dallas Biotin Thickening Shampoo & Conditioner Set, 8.5 oz (2-Pack) — Vegan Volumizing Duo

This two-piece set combines a biotin-enriched shampoo and a weightless conditioner formulated to lift roots, add body, and improve strand resilience without leaving hair heavy or greasy. Scented with R+Co's Dark Waves blend—cardamom, pineapple, tangerine, and lavender—the formula focuses on cosmetic volume and everyday manageability while following clean-beauty standards (100% vegan and cruelty-free).

How does this pair create fuller-looking hair?

The shampoo cleanses the scalp and hair while biotin and other supporting ingredients provide a thicker-looking strand profile, and the conditioner delivers hydration without collapse. Together they create lift at the root and pliable body through the lengths so styles appear bigger and last longer.

• Biotin-enriched shampoo to help hair appear stronger and fuller.
• Lightweight conditioner that hydrates without weighing hair down.
• Designed to add instant visual lift and long-lasting manageability.

Will this set work on chemically-treated or color-treated hair?

Yes — the formulas are free of harsh sulfates and parabens, making them gentler on color‑treated and chemically processed hair than traditional cleansing systems. They’re formulated to support body and softness without stripping color or adding damaging surfactants.

• Sulfate-free cleansing preserves color vibrancy.
• Conditioner restores manageability for processed lengths.
• Cruelty-free and vegan ingredients suited for modern hair care routines.

How do you use the Dallas Thickening Shampoo and Conditioner for best results?

Apply shampoo to wet hair and massage at the scalp to lift impurities and enhance root body; rinse thoroughly. Follow by applying conditioner primarily to mid-lengths and ends, leave on for about two minutes, then rinse to maintain volume without stiffness.

• Massage shampoo into the scalp for root lift; rinse clean.
• Apply conditioner to ends and leave two minutes before rinsing.
• Use regularly for visible fullness and improved styling hold.

What texture, scent, and finish can I expect after using the duo?

Hair feels soft, bouncy, and more voluminous rather than heavy or crunchy. The Dark Waves fragrance layers warm cardamom and lavender over brighter pineapple and tangerine notes for a sophisticated, long-lasting scent profile.

• Soft, manageable finish that supports styling volume.
• Luxurious Dark Waves scent—warm, fresh, and refined.
• Non-greasy, full-bodied look suitable for daily or styling use.

Who is this for? This R+Co Dallas Biotin Thickening Shampoo and Conditioner set is aimed at people with fine, flat, or thinning hair who want cosmetic fullness without heavy products. It’s a good fit for those seeking a clean-beauty option that supports styling volume, for anyone maintaining color-treated or chemically styled hair, and for users who prefer vegan, cruelty-free formulations with a sophisticated scent.
