OGX Thick & Full Shampoo and Conditioner Set, Biotin & Collagen — Purple 25.4 fl oz (2-Pack), Volumizing & Sulfate-Free

OGX Thick & Full + Biotin & Collagen is a two-bottle shampoo and conditioner set formulated to boost the appearance of fine, flat hair for fuller-looking strands without added weight.

This extra-strength volumizing duo combines biotin (vitamin B7) and collagen with protein-rich extracts to help plump each strand and create noticeable body. The sulfate-free formulas are designed for flat to medium-volume hair and are color-safe, leaving hair refreshed, scented with bergamot, jasmine and vanilla, and easier to style. Use the set together for the best thickening and texturizing effect.

How does this set add volume without weighing hair down?

The formulas rely on lightweight proteins and collagen to coat and expand the hair fiber instead of heavy oils that can flatten fine hair. A sulfate-free surfactant base cleanses without stripping, so strands feel lifted from the root to tip.

• Hydrolyzed wheat protein temporarily thickens individual strands.
• Bamboo extract adds texture for fuller appearance.
• Collagen helps fill and smooth the hair surface for body.
• Sulfate-free cleansing preserves natural volume and color.

What’s the right way to use the shampoo and conditioner for maximum fullness?

Apply shampoo to wet hair, massage into a light but thorough lather focusing at the roots, then rinse; follow with conditioner mainly on mid-lengths to ends to avoid flattening the scalp area. For visible lift, rinse the conditioner thoroughly and style while hair is slightly damp to lock in body.

• Shampoo: work into scalp for root lift, then rinse well.
• Conditioner: apply mid-length to ends, avoid heavy application at roots.
• Style damp hair to preserve volume—blow-dry with a round brush for extra lift.
• Use consistently as part of the OGX Biotin & Collagen line for best results.

Is this set suitable for color-treated or chemically processed hair?

Yes—formulated to be color-safe and gentle, the sulfate-free formulas help cleanse and condition without stripping dye or weakening treated hair. The protein and vitamin blend aims to support strand resilience while maintaining color vibrancy.

• Sulfate-free surfactants reduce color fading risk.
• Biotin supports hair integrity after chemical services.
• Collagen and proteins help strengthen fragile, processed strands.
• Recommended for routine use on color-treated hair when paired with color-care products.

Which hair types benefit most from this duo?

This shampoo and conditioner set is targeted at people with fine to medium hair seeking more body, along with anyone who wants thicker-looking hair without heavy buildup. While it adds noticeable texture and fullness, very coarse or extremely dry hair may need additional moisturizing treatments.

• Ideal for flat, limp, or fine hair seeking volume.
• Works well for medium-density hair needing extra lift.
• Color-treated users can use it safely for maintenance.
• Not a deep-hydration treatment for severely dry or coarse hair.

Who is this for: OGX Thick & Full + Biotin & Collagen is designed for shoppers with flat to medium-volume hair who want a lightweight, color-safe system to enhance body and texture. Choose this set if you want fuller-looking hair from root to tip with a complimentary bergamot, jasmine and vanilla scent—and pair it with other OGX Biotin & Collagen products for a complete routine.
