R+Co Dallas Thickening Shampoo — Biotin Formula for Fuller, Stronger Hair (8.5 oz)

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

Formulated by a collective of professional stylists, R+Co Dallas targets thin-looking strands with a blend of biotin, hydrolyzed rice protein, and saw palmetto berry extract to boost fullness, resilience, and shine. The sulfate-free, cruelty-free shampoo gently cleanses while delivering ingredients that support stronger hair architecture and reduced breakage during styling. It’s lightweight enough for daily use and aims to leave hair feeling thicker without weighing it down.

How does this shampoo help hair look thicker?

Dallas works by reinforcing the hair’s internal structure and adding surface body so each strand appears fuller. Biotin supports keratin formation, hydrolyzed rice protein seals moisture and improves flexibility, and saw palmetto adds lift at the root for an overall thicker appearance.

• Biotin strengthens strand infrastructure for improved volume.
• Hydrolyzed rice protein increases shine and reduces breakage.
• Saw palmetto berry extract encourages a fuller root-to-tip look.

Will it help brittle or damaged hair become stronger?

The shampoo contains ingredients that aim to reduce breakage and enhance elasticity, helping fragile hair better withstand brushing and styling. While shampoo alone can’t repair deep internal damage, Dallas helps fortify the hair surface and supports healthier-looking strands over time when used consistently with complementary conditioners and treatments.

• Improves strand resilience through protein-based fortification.
• Locks in moisture to reduce snap and split ends.
• Works best paired with nourishing conditioners or masks.

Is this product suitable for daily use and all hair types?

R+Co Dallas is formulated to be lightweight so it can be used regularly, especially for fine to medium hair that needs lift. Those with very dry, coarse, or color-treated hair should monitor moisture balance and may alternate with a richer cleansing option or follow with a hydrating conditioner.

• Recommended for fine, flat, or thinning-looking hair.
• Safe for color-treated hair when used gently.
• Daily use is appropriate if hair doesn’t become overly dry.

What key ingredients make Dallas effective?

The formula combines targeted actives and conditioning agents to create fuller-looking hair without heaviness. Each ingredient contributes a specific benefit—biotin for keratin support, hydrolyzed rice protein for moisture retention and flexibility, and saw palmetto for root lift—creating a balanced approach to thickening and strengthening.

• Biotin: supports keratin and strand integrity.
• Hydrolyzed Rice Protein: seals moisture and improves shine.
• Saw Palmetto Berry Extract: enhances body and root lift.

Who is this for: R+Co Dallas Thickening Shampoo is aimed at people with fine, limp, or thinning-looking hair who want lightweight volume and improved strand strength without harsh sulfates or animal-derived ingredients. It’s ideal for those seeking a professional-stylist formulation that layers well with volumizing conditioners, root sprays, and styling products to create fuller, more resilient hair and a polished finish.
