HASK Biotin Boost Thickening Shampoo & Conditioner Set 12 oz each — Sulfate-Free, Color-Safe

HASK Biotin Boost Thickening Shampoo + Conditioner is a two-step haircare set designed to add visible fullness and strengthen fine, limp strands without sulfates or parabens.

This paired system combines a fortifying shampoo and a matching conditioner, each 12 oz, formulated to lift roots, improve hair body, and improve manageability while remaining color-safe and free of sulfates, parabens, phthalates, gluten, and drying alcohols. The fragrance is herbaceous and refreshing, and the formulas are intended for regular use to build thicker-looking hair over time. Below you’ll find concise answers to common buying questions and practical details about how the set performs in everyday routines.

How will this set add volume to fine or flat hair?

The Biotin Boost formulas use a tri-level thickening approach to create fuller-looking strands: they work at the fiber level to strengthen, at the root to lift, and at the cuticle to improve body and texture. Gentle cleansing removes residue that can weigh hair down, while the conditioner helps support strand thickness without heavy silicones.

• Shampoo removes buildup and prepares strands for lift.
• Conditioner supplies lightweight moisture and strengthens fiber.
• Biotin-infused blend supports the appearance of thicker hair.

Is this safe for color-treated or chemically processed hair?

Yes — both formulas are labeled color safe and omit sulfates and harsh drying alcohols that can strip dye. The gentler surfactants help preserve color while still providing an effective cleanse for daily or frequent routines.

• Sulfate-free cleansing to minimize color fade.
• No drying alcohols to help maintain moisture balance.
• Color-safe formulation suitable for most salon-treated hair.

What ingredients and claims should I know about?

The set emphasizes biotin for fortifying benefits and a blend that targets volumizing and strengthening. HASK also highlights a clean formulation profile: free from sulfates, parabens, phthalates, gluten, and drying alcohols. The scent is herbaceous, offering a fresh, botanical aroma during use.

• Biotin-focused formulation for strand support.
• Free of sulfates, parabens, phthalates, and gluten.
• Herbaceous fragrance for a refreshing wash experience.

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

Apply shampoo to wet hair, lather at the roots and through lengths, then rinse thoroughly; follow with conditioner focusing on mid-lengths and ends to avoid weighing roots down. For added lift, rinse conditioner fully and style using root-lifting techniques or a blow-dryer with a round brush.

• Use daily or every other day depending on scalp oiliness.
• Concentrate conditioner on mid-lengths and ends, not roots.
• Pair with volumizing styling products if extra lift is desired.

Who is this for: HASK Biotin Boost Thickening Shampoo + Conditioner is aimed at people with fine, limp, or thinning-looking hair who want a gentler, color-safe system to boost volume and strengthen strands. It’s a good match for those seeking a clean-label routine without sulfates or parabens and for users who prefer a lightweight conditioner that won't flatten root lift. If your goal is thicker-looking hair from regular at-home care and you value fragrance and a salon-friendly finish, this set is designed to fit into that daily regimen.
