The Earthling Co. Shampoo Bar — Citrus Sun 3 oz, Vegan Sulfate-Free Solid Shampoo for Dry Hair that Strengthens & Volumizes

The Earthling Co. Citrus Sun Shampoo Bar is a vegan, sulfate- and paraben-free solid shampoo designed to cleanse, add body, and support stronger-feeling hair while being gentle on sensitive scalps.

This 3 oz Citrus Sun shampoo bar swaps bottled formula for a concentrated, low-waste solid that foams like liquid shampoo but comes without silicones, harsh sulfates, or artificial dyes. Formulated with botanicals such as marshmallow root extract and elderberry, plus humectants like glycerin and vitamin B5, the bar aims to hydrate dry strands, lift limp hair, and leave the scalp feeling balanced. The product is cruelty-free, made in the USA, and packaged with eco-friendly materials.

How will this shampoo bar clean my hair compared to a liquid shampoo?

The bar produces an instant, foamy lather that removes oil, product residue, and everyday grime without stripping essential moisture. Because it is concentrated, a little goes a long way, and it rinses clean for soft, manageable hair.

• Foaming solid formula that mimics bottled shampoo performance
• Removes buildup while maintaining hydration
• Concentrated form lasts longer than many liquid equivalents

Can this bar help improve hair thickness and reduce breakage?

Formulated with nourishing plant extracts and strengthening agents, the bar supports fuller-feeling hair by reinforcing strands and reducing visible breakage from daily styling. It’s intended to fortify hair over time when used consistently as part of a gentle care routine.

• Marshmallow root and elderberry help support hair resilience
• Vitamin B5 helps maintain elasticity and shine
• Regular use can make hair appear stronger and less prone to split ends

Will this shampoo bar work for dry, color-treated, or sensitive scalps?

The formulation avoids sulfates, parabens, silicones, phthalates, and harsh soap, making it suitable for many sensitive or treated hair types. It’s pH-balanced, dermatologist-friendly, and includes hydrating ingredients to restore softness to dry or brittle hair.

• Hydrating glycerin and vitamin B5 for moisture and sheen
• pH-balanced blend aimed at minimizing irritation
• Safe for color-treated hair when used as part of a gentle regimen

How do I use and store a shampoo bar for best results?

Wet hair thoroughly, rub the bar between hands or directly on hair to create lather, then massage into scalp and lengths. Rinse completely; repeat if needed. Keep the bar dry between uses on a well-drained soap dish or rack to extend its life.

• Use warm water to activate lather quickly
• Store on a ventilated surface away from standing water
• One bar typically lasts as long as multiple bottles, depending on frequency
