Hawthorne Thick Boost Thickening Shampoo and Conditioner Set — 16 fl oz Each, Sulfate-Free with Biotin

This upgraded Thick Boost kit delivers a larger 16 fl oz bottle of shampoo and conditioner, keeping the eucalyptus-mint Steamroom scent you know while improving the formula to target thin, fragile hair. The pair works together: the shampoo removes buildup and gently cleanses, while the conditioner repairs and supports thicker-looking, fuller-feeling strands using lightweight proteins and vitamins.

How does this set help hair look thicker on busy mornings?

The shampoo creates lift at the roots and the conditioner adds body without heavy silicones, giving hair more natural volume for easier styling. Both products use ingredients that strengthen individual fibers so hair holds a fuller shape through the day.

• Rice protein and panthenol (Vitamin B5) build strand body and texture.
• Sulfate-free surfactants clean without stripping natural oils that add sheen.
• Lightweight conditioning avoids flatness while improving manageability.

What are the key ingredients and what do they contribute?

The formula combines botanicals and vitamins chosen for hair support, not as medical treatments. Biotin and vitamin E help maintain healthy-looking hair, rice protein strengthens and adds volume, and saw palmetto is included as a plant-derived component commonly used in men's grooming formulations.

• Biotin: supports resilient-feeling hair fibers and overall hair health appearance.
• Rice protein: enhances thickness and textural body without heaviness.
• Saw palmetto and olive fruit oil: plant-derived ingredients for scalp and strand nourishment.

Is this set safe for daily use and sensitive scalps?

Yes—this duo is free from sulfates, parabens, silicones, phthalates, and artificial dyes, making it a gentler option for frequent washing. The formulation is vegan and cruelty-free, designed to reduce common irritants while still delivering effective cleansing and conditioning.

• Sulfate-free cleansers reduce dryness from harsh detergents.
• No parabens or phthalates lowers exposure to certain synthetic preservatives and plasticizers.
• Vegan and cruelty-free standards accommodate ethical preferences.

How will this pair smell and how long does the scent last?

The scent follows Hawthorne’s Steamroom inspiration: a fresh eucalyptus-mint profile with subtle cologne-like depth. It’s designed to be noticeable after washing and fade naturally through the day without overpowering cologne or leave-on products.

• Eucalyptus-mint top notes for a fresh, invigorating wash.
• Cologne-quality base for a mature, clean aroma.
• Formulated to complement — not compete with — daily fragrances.

Who is this for: Hawthorne Thick Boost Shampoo and Conditioner suits men seeking fuller-looking hair without heavy styling products or harsh detergents. It’s a practical choice for guys with naturally fine, thinning, or damaged hair who want a daily-friendly routine that adds volume, strengthens strands, and leaves a clean, masculine scent. If you prefer products that are vegan, cruelty-free, and free from sulfates and parabens, this larger-size set offers more value while fitting into a straightforward grooming regimen.
