OGX Thick & Full Biotin + Collagen Volumizing Shampoo & Conditioner — 2-Pack 13 fl oz, Sulfate-Free

This two-piece kit combines vitamin B7 (biotin) and collagen with gentle, sulfate-free surfactants to cleanse, hydrate, and help visibly thicken fine, flat, or thinning hair. The formulas are paraben free, color-safe, and scented with bergamot, jasmine, and vanilla to leave hair smelling fresh. Use the shampoo to lift and clarify roots, then follow with the conditioner to detangle and smooth while preserving volume.

How does this set increase hair volume and body?

The biotin-and-collagen blend targets strands by helping them appear fuller and plumper: biotin supports the look of stronger hair while collagen helps add surface thickness. The lightweight conditioner seals cuticles without flattening, so hair keeps lift at the root and improved texture along the lengths.

• Biotin and collagen work together to enhance strand fullness.
• Lightweight conditioning prevents weighed-down hair.
• Sulfate-free surfactants gently cleanse while preserving volume.

Will this be gentle on color-treated or damaged hair?

Yes — the formulas are designed to be color-safe and free of harsh sulfates, which helps reduce color stripping during cleansing. The conditioning components add moisture and detangling support to help minimize breakage on treated or fragile hair.

• Sulfate-free shampoo protects color vibrancy.
• Paraben-free conditioner adds hydration without heaviness.
• Nutrient-infused blend supports improved manageability.

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

Apply the shampoo generously to fully wet hair, massage to create a rich lather, and rinse thoroughly to remove product buildup. Follow with the conditioner, focusing on mid-lengths to ends for detangling; leave on briefly then rinse to retain buoyant volume.

• Shampoo: apply to wet hair, lather, and rinse completely.
• Conditioner: concentrate on mid-lengths and ends, rinse after brief dwell time.
• Use regularly for cumulative appearance of fuller hair.

What hair types and concerns does this duo address?

This set is formulated for fine, flat, or thinning hair but remains versatile enough for dry, oily, frizzy, or chemically treated hair that needs lift and improved texture. It focuses on visual thickness and manageability rather than altering hair structure, making it suitable for daily routines.

• Ideal for fine, limp, or thinning hair seeking volume.
• Suitable for color-treated and chemically processed hair.
• Works for a range of textures needing lightweight moisture and lift.

Who is this for: OGX Thick & Full + Biotin and Collagen is aimed at anyone who wants fuller-looking hair without heavy creams or silicones — particularly people with fine or thinning strands, those maintaining color-treated hair, and anyone seeking a gentle, everyday volumizing shampoo and conditioner. If your goal is more body, improved detangling, and a pleasant, long-lasting fragrance while keeping formulas sulfate- and paraben-conscious, this set is a practical addition to your routine.
