Hawthorne Thick Boost Shampoo & Conditioner Set, 16 fl oz Each — Biotin & Rice Protein for Fuller-Looking Hair

This upgraded Thick Boost pair combines concentrated formulas and larger 16 fl oz bottles of shampoo and conditioner that use biotin, rice protein, saw palmetto and vitamin E to support healthier-looking hair. The set keeps a fresh eucalyptus mint scent and removes common harsh ingredients—no sulfates, parabens, silicones, phthalates, or animal testing—while delivering lightweight moisture and fortifying nutrients in every wash.

How does this set make hair appear thicker?

The shampoo gently cleanses and primes strands while the conditioner strengthens and adds lift at the roots for fuller-looking hair. Together they improve strand resilience and reduce limpness so hair looks denser and moves with more volume.

• Biotin and vitamin E to support overall strand strength.
• Rice protein provides body without heaviness.
• Saw palmetto helps create a balanced scalp environment.
• Sulfate-free surfactants preserve hair’s natural moisture.

Will the conditioner weigh my hair down?

No—the Thick Boost conditioner is formulated to rebuild damaged fibers and add moisture without coating hair in heavy oils. It uses lightweight hydrators and protein to reinforce hair structure while preserving natural movement and volume.

• Light, fast-absorbing texture that rinses clean.
• Rice protein repairs and reinforces without residue.
• Pantothenic acid (vitamin B5) to improve softness and manageability.
• Olive fruit oil provides targeted nourishment, not heavy coating.

What ingredients power the Thick Boost formulas?

The set blends proven, naturally derived actives with modern haircare excipients to support fuller-looking hair and scalp health. Ingredients are selected to strengthen, fortify and add body while avoiding common irritants and harsh detergents.

• Biotin for thicker-feeling strands and improved texture.
• Rice protein to add lift and structural support.
• Saw palmetto to help maintain a balanced scalp environment.
• Vitamin E and olive fruit oil for antioxidant protection and hydration.

How will this fit into my daily routine?

The system works as an everyday wash-and-condition solution for men seeking fuller-looking hair with minimal fuss. Use the shampoo to cleanse and the conditioner to strengthen and detangle; follow with styling as usual to maximize volume and hold.

• Wet hair, apply shampoo, lather and rinse thoroughly.
• Apply conditioner mid-lengths to ends, leave 1–2 minutes, then rinse.
• Safe for daily use thanks to gentle, sulfate-free cleansing agents.
• Pairs well with volumizing styling products for added lift.

Who is this for: Men who want a simple, effective way to make thinning or fine hair appear fuller without heavy conditioners or harsh chemicals. It’s ideal for anyone seeking a clean-label daily shampoo and conditioner with volume-enhancing proteins and vitamins, plus a refreshing eucalyptus mint scent inspired by Hawthorne's Steamroom cologne.
