Hawthorne Thick Boost Men’s Thickening Shampoo & Conditioner Set — 16 fl oz Each, Biotin + Rice Protein for Volume

Hawthorne Thick Boost Shampoo and Conditioner Set is a sulfate- and paraben-free men’s hair duo formulated with biotin, rice protein, saw palmetto, and vitamin E to help strengthen and add volume to thinning hair.

This two-piece set (16 fl oz each) is designed to clean, fortify, and visibly lift hair without weighing it down. The updated formula keeps the eucalyptus-mint Steamroom-inspired scent while increasing size and improving active ingredients so you get more value and fuller-feeling hair from each wash. The pair is free of sulfates, parabens, silicones, phthalates, and is vegan and cruelty-free.

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

The shampoo gently cleanses while the conditioner rebuilds strands to create a fuller silhouette with natural movement. Instead of heavy waxes or silicones, plant-derived proteins and vitamins support strand strength so hair holds volume without stiffness.

• Rice protein plumps and adds body to each strand
• Biotin supports hair resilience and reduces breakage
• Lightweight conditioning prevents flattening at the roots
• Cologne-quality eucalyptus-mint scent for an instant fresh finish

What ingredients are responsible for strengthening and protecting hair?

Key actives in the formula were chosen to support thicker-feeling and healthier-looking hair without harsh detergents. Nutrient-rich components work together to nourish the scalp, reinforce fragile strands, and shield hair from everyday wear.

• Biotin: helps maintain stronger hair and reduces fragility
• Rice protein: fortifies strands to improve texture and volume
• Saw palmetto: commonly used to support scalp health
• Vitamin E & olive fruit oil: condition and add shine while protecting hair fiber

Will this damage-colored or treated hair?

The sulfate-free formulation avoids aggressive surfactants that strip color, making the set compatible with dyed and chemically treated hair when used as directed. The conditioning phase focuses on reconstruction and moisture balance without heavy residues that dull color.

• Sulfate-free cleansing to reduce color fade
• Light conditioning agents that detangle without buildup
• Free from silicones and harsh preservatives for gentler care
• Safe for routine use to maintain manageability and shine

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

Use the shampoo to remove oil and product, then apply conditioner to mid-lengths and ends to restore strength. For noticeable lift, focus the conditioner away from roots and rinse thoroughly; style as usual.

• Wet hair thoroughly and shampoo with a small amount; rinse
• Apply conditioner to mid-lengths and ends, leave 1–2 minutes, then rinse
• Use 2–3 times weekly or as needed depending on scalp oiliness
• Pair with styling products for extra hold or texture when desired
