OGX Thick & Full Biotin & Collagen Shampoo + Conditioner Set, Purple 2-Pack — Sulfate-Free, Volume-Boosting (25.4 fl oz each)

OGX Thick & Full + Biotin & Collagen is a sulfate-free shampoo and conditioner duo formulated to visibly boost body and texture in flat to medium-volume hair.

Designed for people who want more lift without heavy buildup, this two-pack contains a 25.4 fl oz bottle of shampoo and a matching 25.4 fl oz conditioner. The formulas combine biotin (pro‑vitamin B7), collagen and plant-derived proteins to help fill and plump individual strands while remaining color-safe. A light bergamot, jasmine and vanilla aroma leaves hair smelling fresh without overpowering.

How does this set increase volume without weighing hair down?

The shampoo uses a gentle, sulfate‑free surfactant system paired with hydrolyzed wheat protein and bamboo fiber extract to coat and support each strand, creating the perception of thicker hair. The conditioner provides extra strength conditioning that smooths cuticles but rinses clean so hair keeps lift at the roots.

• Biotin and collagen for strand‑plumping support
• Hydrolyzed wheat protein increases texture and elasticity
• Sulfate‑free surfactants avoid heavy residue
• Lightweight conditioning preserves root lift

Will this set work on color‑treated or fine hair?

Yes — the formulas are developed to be color-safe and gentle on chemically treated hair while still delivering extra body for fine to medium strands. The conditioner is concentrated on strengthening and smoothing rather than adding weight, so color vibrancy and manageability are preserved.

• Color-safe ingredients protect dyed hair
• Formulation tailored for flat to medium volume
• Helps detangle without heavy silicones
• Safe for routine use in most hair care systems

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

Apply the shampoo to thoroughly wet hair, massage to a lather focusing at the scalp, and rinse. Follow with conditioner from mid-length to ends, comb through for even distribution, leave for a minute and rinse. For fuller results, pair with other products from the OGX Biotin & Collagen line.

• Shampoo: massage into scalp, rinse completely
• Conditioner: apply to mid-lengths and ends, leave briefly
• Use regularly — consistent use builds visible texture
• Combine with complementary OGX styling items for added volume

What sensory experience can I expect from scent and texture?

The duo delivers a lightweight lather and a silky conditioner finish that won’t feel heavy. Fragrance notes of bergamot, jasmine and vanilla provide a pleasant, modern aroma that lingers subtly after styling, striking a balance between fresh and warm.

• Rich but non-greasy lather from the shampoo
• Conditioner detangles and smooths without heaviness
• Warm floral-citrus fragrance blends for everyday wear
• Large 25.4 fl oz bottles for long-term use

Who is this for: This OGX Thick & Full + Biotin & Collagen 25.4 fl oz two-pack is aimed at people with fine, limp or medium‑volume hair who want more body and texture without heavy residue.

If you prefer lightweight conditioning, enjoy a subtle fragrance, and want bottles large enough for frequent use, this set is a practical option to add visible lift and manageability to your routine.
