RENPURE Biotin & Collagen Leave-In Conditioner Spray — 8 fl oz, Lightweight Volume & Detangling for Fine or Thin Hair

RENPURE Biotin & Collagen Leave-In Conditioner is a lightweight spray treatment that helps fine, limp hair look fuller and shinier without weighing it down.

This leave-in formula combines Vitamin B7 (biotin) and collagen to visibly boost body and manageability while delivering moisture and detangling benefits. Designed for daily use, the spray works on damp hair so you can comb, style, and go — no rinse required. The product is vegan, cruelty-free, and formulated without sulfates, parabens, silicones, mineral oil, petrolatum, or gluten, and comes in a fully recyclable bottle and lid.

How does this formula add body to fine or thin hair?

The biotin supports hair shaft resilience while collagen provides lightweight protein and moisture retention that increases the appearance of thickness. Together they help hair lift at the roots and maintain fuller-looking strands without a heavy residue. Results are most noticeable with consistent use and when paired with a complementary shampoo and conditioner.

• Vitamin B7 (biotin) to support structural strength of hair strands
• Collagen to add protein and moisture for improved density appearance
• Weightless spray format that won’t flatten fine hair
• Daily use recommended and compatible with styling products

What’s the best way to use the leave-in treatment for visible lift?

Apply the spray evenly to towel-dried hair, focusing on roots and mid-lengths, then comb through to distribute the formula. Do not rinse; style as usual — blow-drying with a round brush will help amplify body. For a fuller regimen, use alongside RENPURE Biotin & Collagen Shampoo and Conditioner.

• Spray on damp hair, root to tip
• Comb through to detangle and even coverage
• Style immediately; no rinsing required
• Use daily for best cumulative effect

Is this leave-in spray safe for colored or chemically treated hair?

The formula is free from sulfates and parabens, which makes it gentle enough for many color-treated or chemically processed hair types. Because it’s free of silicones and heavy oils, it won’t create buildup that can dull color or weigh hair down. If you have specific concerns about a treatment, perform a strand test or check with your stylist.

• Sulfate- and paraben-free to reduce stripping of color
• No silicones or heavy petrolatum that cause buildup
• Suitable for regular styling routines when used as directed
