RENPURE Biotin & Collagen Thickening Shampoo and Conditioner Set 24 oz — Sulfate-Free, Volumizing Duo for Fine Hair

RENPURE Biotin & Collagen Thickening Shampoo and Conditioner is a sulfate-free hair set formulated with biotin and collagen to help fine hair look and appear fuller and healthier.

This two-step system combines Vitamin B7 (biotin) and collagen-derived proteins in a shampoo and matching conditioner to add body and manageability to fine or thinning-looking hair. Both 24 oz bottles are made from recycled plastic and the formulas exclude sulfates, parabens, dyes, gluten, phthalates, and propylene glycol. The pairing is designed for daily use, delivering gentle cleansing followed by conditioning to detangle and smooth without weighing hair down.

How does this set create more noticeable volume?

The shampoo gently cleanses while ingredients like biotin and protein work to coat and temporarily thicken individual strands, so hair feels fuller to the touch. The conditioner deposits lightweight conditioning agents and proteins that help maintain lift at the roots and reduce flattening through the lengths.

• Biotin (Vitamin B7) supports strand structure for a fuller appearance.
• Collagen-derived proteins add temporary body and texture.
• Sulfate-free surfactants cleanse without stripping natural oils.
• Lightweight conditioning avoids heavy buildup that can weigh hair down.

Will this work for colored or chemically treated hair?

The formula avoids harsh sulfates and common irritants that can accelerate color fade or stress chemically treated hair. While not a color-preservation system, the gentler cleansing and conditioning help maintain softness and manageability after salon services.

• No sulfates or parabens that can strip color quickly.
• Free from dyes and phthalates to reduce exposure to unnecessary additives.
• Suitable for routine use on many hair types after color or chemical services.

How should I use the shampoo and conditioner for best results?

Use the shampoo to thoroughly cleanse the scalp and lengths, then rinse and apply the conditioner from mid-length to ends, avoiding heavy application at the roots if you tend to have flat hair. Rinse with cool to lukewarm water for smoother cuticles and repeat as needed depending on hair type and styling routine.

• Apply shampoo to wet hair, lather, then rinse completely.
• Work conditioner through mid-lengths and ends for 1–3 minutes, then rinse.
• For added lift, rinse roots thoroughly and concentrate conditioner away from the scalp.
• Use regularly as part of a daily or frequent washing schedule.

What ingredients are intentionally left out and why does that matter?

RENPURE omits sulfates, parabens, dyes, gluten, phthalates, and propylene glycol to minimize exposure to common irritants and to provide a gentler wash experience. Bottles are made from recycled plastic, reflecting a lower-waste packaging choice.

• ZERO sulfates and parabens to reduce harsh stripping and potential irritation.
• No added dyes or gluten for simpler formulas and fewer unnecessary additives.
• Recycled plastic bottles for a reduced environmental footprint.
• PETA animal-test-free certification for cruelty-free sourcing.

Who is this for: This 24 oz RENPURE Biotin & Collagen Thickening Shampoo and Conditioner set is suited to anyone seeking a gentler daily shampoo and conditioner duo that aims to make fine or limp hair feel fuller and more manageable. It's a good match for people who prefer formulas without sulfates or parabens, those looking for recyclable packaging, and shoppers who prioritize cruelty-free products. If your hair is very dry, textured, or requires intensive repair, you may want to pair this set with a richer weekly mask or targeted treatment tailored to those needs.
