RENPURE Biotin & Collagen Thickening Shampoo 32 fl oz — Sulfate-Free, Color-Safe Volume Boost

RENPURE Biotin & Collagen Thickening Shampoo is a plant-based, sulfate-free cleanser formulated with biotin, collagen and keratin to boost the look of fuller, stronger hair while remaining safe for color-treated strands.

This 32 fluid ounce bottle delivers a daily shampoo that combines vitamin B7 (biotin) with collagen and keratin to help hair appear thicker and more resilient. The formula avoids harsh sulfates, sodium chloride, parabens, dyes and gluten, relying instead on gentle plant-derived cleansers and proteins to reduce scalp irritation while supporting shine and body. Ideal for a wide range of hair types, it works well for curly, processed, or fine hair where added fullness is desired.

How does this shampoo build the appearance of thicker hair?

The shampoo blends biotin with structural proteins to coat and reinforce each strand, improving texture and visible density. Regular use can help hair look more voluminous without heavy residue.

• Biotin (vitamin B7) nourishes hair fibers for improved strength.
• Collagen and keratin add protein support to increase body.
• Plant-based cleansers remove buildup without stripping natural oils.
• Lightweight finish avoids weighing hair down.

Is this safe for color-treated or chemically processed hair?

Yes — the formula is free from sulfates and harsh salts that often contribute to color fading and dryness. Its gentle surfactants and nourishing proteins help maintain moisture balance while protecting dyed hair.

• No sodium chloride or sulfates to strip color.
• Free of parabens and dyes that can irritate sensitive scalps.
• Plant-derived ingredients support a softer, shinier finish on treated hair.
• Suitable for frequent washing routines.

What kind of scalp and hair types benefit most from this product?

The shampoo is formulated for people seeking added volume and strength, including those with fine, thinning, curly, or color-treated hair. Its mild cleansing system helps reduce scalp irritation while enhancing texture.

• Fine or limp hair that needs lift and body.
• Curly hair that needs gentle cleansing without frizz-inducing sulfates.
• Color-treated or chemically processed hair requiring a milder formula.
• Anyone wanting plant-based, gluten-free haircare ingredients.

How should I use it for best results?

Apply to wet hair, massage into the scalp to create a light lather, and rinse thoroughly. For added thickness, follow with a Renpure conditioner or a protein-rich treatment; use regularly as part of your haircare routine.

• Wet hair then work a small amount into scalp and lengths.
• Rinse and repeat if hair is very oily or product-heavy.
• Pair with a hydrating or strengthening conditioner from Renpure.
• Use consistently to maintain texture and body improvements.
