Soapbox Biotin & Super Fruit Shampoo and Conditioner Set — 16 oz Each, Volumizing, Strengthening Vegan Formula

Soapbox Biotin & Super Fruit Shampoo and Conditioner is a two-step haircare set formulated to boost volume and strengthen hair using biotin, elderberry, plum oil, and vegan collagen in sulfate- and silicone-free formulas.

This paired shampoo and conditioner arrives in 16 oz bottles designed for daily use on a range of hair types and textures. The set aims to gently remove buildup while preserving moisture, add lift and body, and support the look of fuller, healthier hair using plant-forward and vegan ingredients. Soapbox also donates a bar of soap to someone in need with each purchase, supporting social impact alongside haircare.

How will this set affect limp or fine hair?

The Biotin & Super Fruit duo focuses on adding visual body and lightweight support so hair appears fuller without feeling weighed down. Biotin and vegan collagen are included to improve the feel of thickness, while the conditioner provides slip and detangling without heavy silicones.

• Shampoo gently clears residue to allow natural volume to lift at the roots.
• Conditioner smooths cuticles and adds conditioned texture for styling hold.
• Lightweight emollients prevent flattening common with richer formulas.

Will the formulas work with color-treated or chemically processed hair?

These products are formulated to be color safe and free of harsh sulfates, enabling gentler cleansing compared with traditional sulfate systems. The absence of parabens and silicones reduces the risk of rapid color dulling from heavy film build-up.

• Sulfate-free cleansing helps protect color vibrancy between salon visits.
• Conditioner restores manageability without masking color with silicone residue.
• Suitable for many chemical services, but always patch-test when in doubt.

What ingredients deliver the strengthening and fruit-derived benefits?

Key actives include biotin and vegan collagen for the appearance of strength and fullness, with super fruit extracts like elderberry and plum oil contributing antioxidants and conditioning lipids. Together, they aim to improve texture and shine while maintaining hydration balance.

• Biotin — supports the look of fuller, more resilient hair strands.
• Plum oil — lightweight nourishment that enhances softness and sheen.
• Elderberry and plant extracts — natural-derived components for antioxidant support.

How should I use the shampoo and conditioner in my routine?

Start with a small amount of shampoo, emulsify with water and massage through wet hair, concentrating on the scalp, then rinse thoroughly. Follow with conditioner applied mid-length to ends, leave for 1–2 minutes if needed, then rinse; style as normal.

• Use daily or every few days depending on scalp oiliness and styling products.
• For best volume, blow-dry with roots lifted or use a lightweight styling mousse.
• Pair with a clarifying routine monthly if you use heavy styling products.

Who is this for: This Soapbox Biotin & Super Fruit Shampoo and Conditioner set is aimed at people seeking lightweight volumizing and strengthening benefits without harsh sulfates, parabens, or silicones. It suits fine to medium hair types and those with color-treated hair who want a plant-forward, vegan option. Buyers who value social impact will also appreciate Soapbox’s soap-donation program tied to each purchase.
