Soapbox Biotin & Super Fruit Shampoo & Conditioner Set, 1 L Each — Volumizing, Sulfate-Free

This two-bottle set pairs a gentle cleansing shampoo and a conditioning treatment designed to enhance fullness and resilience while respecting natural moisture balance. Free from harsh sulfates, parabens, and silicones, the formulas rely on biotin plus fruit-derived oils like elderberry and plum to target limp, damaged, or thinning-looking hair. Each liter bottle supports daily use, color-safe routines, and a cruelty-free, vegan approach—plus Soapbox donates a bar of soap with every purchase.

How does this set increase hair volume without weighing hair down?

The shampoo uses mild cleansers and lightweight conditioning agents that remove product buildup while preserving essential oils. The conditioner contains biotin and vegan collagen that help improve strand strength and body without heavy silicones that can flatten hair.

• Biotin helps support hair feeling fuller and more resilient.
• Lightweight plum oil provides moisture without heaviness.
• Sulfate- and silicone-free base prevents buildup that reduces volume.
• 1 L bottle sizes allow consistent daily use for cumulative improvement.

What ingredients make this duo suitable for damaged or thin-looking hair?

The formulas emphasize nutrient-rich fruit extracts and vegan collagen to temporarily strengthen and plump the hair shaft while cleansing safely. These components work together to smooth cuticles, reduce breakage during styling, and help hair appear healthier over time.

• Biotin supports the appearance of thicker, fuller hair.
• Elderberry extract adds antioxidant-rich nourishment to strands.
• Vegan collagen helps reinforce and improve elasticity in weak areas.
• Plum oil seals in moisture without leaving residue.

Will this set work for color-treated or sensitive scalps?

Yes—both products are formulated to be color-safe and gentle on the scalp. The absence of sulfates reduces aggressive stripping of color and natural oils, while the clean ingredient profile minimizes common irritants for many sensitive scalps.

• Sulfate-free formula better preserves hair dye vibrancy.
• No parabens or silicones that can irritate or build up on hair.
• Vegan, cruelty-free composition fits many lifestyle preferences.
• Designed for daily use across multiple hair textures and types.

How do I incorporate the shampoo and conditioner into my routine for best results?

Start by applying shampoo to wet hair, massaging the scalp to lift buildup, then rinse thoroughly. Apply conditioner from mid-lengths to ends, leave on one to three minutes, then rinse; use consistently to notice fuller-looking hair and improved manageability.

• Use a quarter-sized amount of shampoo for short hair, larger for long or thick lengths.
• Concentrate conditioner on ends to avoid weighing roots down.
• Weekly deep conditioning or a clarifying wash can complement the set.
• Regular use across multiple washes supports cumulative strengthening.
