HASK Biotin Boost Thickening Shampoo — 12 fl oz Volumizing, Sulfate-Free for Fuller, Lifted Roots

HASK Biotin Boost Thickening Shampoo is a volumizing shampoo formulated with biotin, collagen and coffee to help hair appear fuller, stronger and lifted at the roots.

Fine or limp hair often needs targeted ingredients to create visible body without weighing strands down. HASK Biotin Boost Thickening Shampoo uses a tri-level formula—biotin for appearance of thickness, collagen for fortification, and coffee extract for added lift—to cleanse while supporting a fuller look. It’s sulfate-free and designed to work as the first step in a routine that prioritizes volume and manageability.

How does HASK Biotin Boost Thickening Shampoo create fuller-looking hair?

This shampoo combines actives chosen to enhance the look and feel of thin hair. Biotin helps hair appear thicker by coating strands, collagen supports structure, and coffee extract adds body and bounce. Together they cleanse away oils that flatten hair so each strand sits with more separation and lift.

• Biotin: coats strands for increased visual thickness
• Collagen: reinforces hair structure for firmer texture
• Coffee extract: boosts root lift and improves body
• Gentle surfactants: remove buildup without heavy residue

Will this shampoo work for color-treated or chemically processed hair?

HASK formulas are typically free of harsh sulfates and designed to be gentle, making this shampoo compatible with many color-treated and processed hair types. As with any product, test on a small area first if your hair has recent chemical work or sensitive scalp conditions.

• Sulfate-free cleansing suitable for color-treated strands
• Formulated to avoid unnecessary dryness or stripping
• Use with a complementary conditioner for balanced moisture

How should I use the shampoo for best volume results?

Apply a small amount to wet hair, focusing on the scalp and roots, then gently massage to lift oils and buildup. Rinse thoroughly and follow with a volumizing conditioner or lightweight rinse-out treatment to preserve lift without weighing hair down.

• Wet hair thoroughly before shampooing
• Massage into roots for lift and full-length for cleansing
• Rinse, then use a lightweight conditioner on mid-lengths and ends

How quickly can I expect to see a difference?

Immediate effects are usually cosmetic—cleaner, brighter hair with more visible lift at the roots after the first wash. Ongoing use may improve the look of thickness as actives continue to support strand strength and fullness; individual results vary based on hair type and condition.

• First wash: cleaner texture and noticeable root lift
• Continued use: improved strand separation and body over time
• Combine with styling and conditioning for optimal results

Who is this for? HASK Biotin Boost Thickening Shampoo is formulated for people with fine, limp or thinning-appearing hair who want lightweight volume and a fuller look without heavy buildup. It suits those seeking a gentle, performance-driven cleanser to use as part of a volume-focused haircare routine—especially anyone looking to add root lift, improve strand texture, and maintain color-treated hair without harsh sulfates.
