R+Co Dallas Thickening Shampoo — Biotin-Infused Volume for Fine Hair, Vegan Cruelty-Free | 8.5 oz

R+Co Dallas Thickening Shampoo is a biotin-forward, vegan cleansing formula designed to add body and strengthen fine, flat hair from root to tip.

Formulated by the stylist collective R+Co, DALLAS combines targeted actives and gentle surfactants to lift limp strands, improve tensile strength, and leave hair with more visible volume and resilience. It’s made without animal-derived ingredients, so it suits shoppers seeking performance with cruelty-free credentials.

How does this shampoo add thickness without weighing hair down?

DALLAS uses lightweight proteins and botanical extracts to create fuller-looking hair without heavy silicones or waxy agents. The shampoo cleanses buildup while depositing film-forming and strengthening molecules that make each strand appear denser.

• Hydrolyzed rice protein: builds body and reduces breakage while staying light.
• Saw palmetto berry extract: adds palpable surface body for lift.
• Biotin-infused formulation: helps support keratin structure and strand strength.
• Gentle foaming base: removes residue that flattens fine hair.

What ingredients deliver the strengthening and vitality benefits?

The key actives in DALLAS target hair structure and surface texture to improve manageability and appearance. They focus on bolstering the protein matrix, locking in moisture, and protecting against mechanical stress from styling.

• Biotin: supports the hair’s keratin framework for stronger-feeling strands.
• Hydrolyzed rice protein: enhances shine, flexibility, and resistance to breakage.
• Saw palmetto berry extract: contributes to fuller-looking, thicker hair texture.
• Vegan base: cleanses without animal-derived thickeners that can weigh hair down.

How should I use R+Co Dallas to get the best results?

For optimal lift and strength, apply DALLAS to wet hair, work into a rich lather focusing on roots, then rinse and follow with a compatible conditioner or lightweight treatment. Use regularly in place of your usual shampoo for cumulative improvement in body and manageability.

• Wet hair thoroughly and apply a quarter-sized amount; adjust by length and density.
• Massage into scalp and mid-lengths for full coverage and lift at the roots.
• Rinse thoroughly and pair with R+Co conditioner for added smoothness.
• Use consistently—daily or every other day depending on scalp oiliness—for visible volume changes.

Is this shampoo suitable for color-treated or sensitive scalps?

DALLAS is formulated to be gentle and compatible with many color-treated routines, though individual sensitivity varies. It avoids harsh denaturing ingredients, but if you have a very reactive scalp or recent professional color, patch-test or check with your colorist.

• Free of animal-derived ingredients and cruelty-free.
• Contains gentle cleansing agents designed to preserve color vibrancy.
• Patch-test recommended for highly sensitive scalps or recent chemical services.

Who is this for: R+Co Dallas Thickening Shampoo is intended for people with fine, flat, or limp hair who want lightweight volume, improved strand strength, and a fuller visual texture without heavy buildup. It’s a good choice for shoppers seeking salon-grade formulas that are vegan and cruelty-free, and for anyone who wants a routine that supports thicker-looking hair while maintaining softness and manageability.
