Herbalosophy Biotin & Collagen Shampoo & Conditioner Set — 2 x 16.9 fl oz, Thickening & Repair with Argan Oil

Herbalosophy Biotin & Collagen Shampoo & Conditioner Set is a two-bottle hair regimen formulated with vitamin B7, collagen and argan oil to help strengthen, smooth and visibly thicken fine, dry or damaged hair.

This duo combines a gentle cleansing shampoo and a rich conditioner designed to support hair that looks fragile or limp. The sulfate-, paraben- and gluten-free formula aims to preserve color while helping reduce breakage from everyday styling. With balanced pH levels for both bottles, the set focuses on improving manageability and softness without stripping natural oils.

How does this set help hair feel thicker and stronger?

The shampoo and conditioner work together so strands appear fuller while feeling fortified. Biotin (vitamin B7) supports the hair’s surface integrity, and collagen helps provide smoothing support to the shaft. Argan oil adds hydration and shine without weighing hair down.

• Biotin helps reduce brittleness for improved elasticity.
• Collagen supports smoother, fuller-looking strands.
• Argan oil conditions and adds visible shine.
• Color-safe, non-sulfate base protects hair pigments.

Will this set work on dry, damaged or color-treated hair?

Yes — the formula is created to be gentle enough for damaged and color-treated hair while still providing conditioning benefits. The conditioner’s lower pH helps close the cuticle for smoother texture and easier detangling. Because it’s free of sulfates and parabens, it’s less likely to strip color or essential moisture.

• Shampoo pH 5.5–6.5 preserves scalp balance.
• Conditioner pH 4.5–5.5 helps seal and smooth hair cuticles.
• Sulfate- and paraben-free to protect color and moisture.
• Formulated to detangle and reduce further damage.

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

Use the shampoo to cleanse thoroughly, focusing on the scalp, then rinse. Apply the conditioner from mid-lengths to ends, leave on briefly, and rinse for softer, more manageable hair. Consistent use as part of a regular hair care routine yields the best visible improvement in texture and resilience.

• Wet hair and apply shampoo to the scalp; lather and rinse thoroughly.
• Distribute conditioner through lengths; leave 1–3 minutes for absorption.
• Rinse with cool or lukewarm water to help seal cuticles.
• Use 2–3 times weekly or as needed for daily maintenance.

What ingredients are highlighted and why do they matter?

This set spotlights vitamin B7 (biotin), collagen and argan oil as core actives for strength, texture and moisture. Biotin supports hair surface strength, collagen contributes smoothing support, and argan oil nourishes strands for improved shine and softness.
