Marc Anthony Instantly Thick Biotin Shampoo — Lightweight Volumizing Shampoo for Fuller, Thicker Hair (Aloe & Phytokeratin)

Marc Anthony Instantly Thick Biotin Shampoo is a lightweight volumizing shampoo formulated with biotin, thickening polymers and phytokeratin to give fine, flat hair the appearance of fuller, stronger strands.

This shampoo cleanses while adding visible body and manageability without leaving a waxy residue. The formula pairs strengthening actives like biotin and phytokeratin with conditioning botanicals such as aloe, sunflower oil and vitamin E, producing lift at the roots and smoother mid-lengths for easier styling. It’s designed to deliver a noticeable boost in fullness from the very first wash and works best when used alongside the matching conditioner.

How does this shampoo add volume without weighing hair down?

The blend of lightweight thickening polymers and biotin creates body at the hair shaft without heavy oils or silicones that flatten fine hair. Phytokeratin helps reinforce strands so they hold shape better, while aloe and vitamin E add hydration and slip for smooth comb-through.

• Biotin supports hair’s structure for a fuller look.
• Thickening polymers lift and coat strands without heaviness.
• Phytokeratin improves resilience and helps hair keep volume.
• Aloe and sunflower oil add moisture and shine without tackiness.

Will this work on all hair types, including color-treated hair?

This lightweight formula is safe for most hair types, from fine to medium, and is gentle enough for color-treated hair because it avoids harsh sulfates and parabens. It focuses on creating instant volume rather than chemical restructuring, making it a versatile choice for everyday use.

• Paraben-free, sulfate-free, phthalate-free formulation.
• Suitable for fine, flat, and dry hair seeking lift and body.
• Color-safe when used as a regular cleansing step.
• Pair with the Instantly Thick + Biotin Conditioner for best results.

How do I use it for maximum thicker-looking results?

Start with wet hair, apply a palm-sized amount, lather at the roots and work through to the ends, then rinse thoroughly. Follow with the matching conditioner to lock in volume and manageability; styling with a root-lift mousse or blow-drying with a round brush enhances the effect.

• Apply to wet hair, lather, and rinse for daily use.
• Use the full Instantly Thick + Biotin system for complementary benefits.
• Blow-dry or style while damp to amplify volume at the roots.
• Adjust amount based on hair length and thickness for best coverage.

What ingredients should I expect and what do they do?
