THE EARTHLING CO. SHAMPOO BAR: Experience improved hair health with more moisture, volume, and growth. Our bars create a rich, foamy lather that gently removes build up without stripping your hair from its natural moisturizing oils. Marshmallow Root works like magic to strengthen hair and support new healthy hair growth while also drawing water into the hair follicle to lock in moisture and make your strands feel thicker, contributing to more volume. Rich in fatty acids, jojoba oil provides much-needed moisture and nourishment to scalp and strands without flattening or weighing hair down. Vitamin B5 restores shine and luster in dull hair while improving its strength and preventing breakage. Last but not least, our guar bean-derived conditioning agent, makes your hair soft, moisturized, and manageable while reducing frizz and flyaways. Our formula was designed to work with all hair types (curly, wavy, straight, gray, color-treated, dry, oily) which means it doesn\'t contain any sulfates, phthalates, silicones, parabens, artificial fragrances, or dyes - common ingredients that can wear down your hair or scalp health over time. Our formula is dermatologist reviewed and approved, pH-balanced, contains organic ingredients and is biodegradable. Its safe for sensitive skin and comes in 6 different scents, including a fragrance-free option for those with extra sensitive skin. Our Strengthening and Volumizing Shampoo Bar is easy to use: Wet your hair, lather the bar in your hands or directly on your head, massage into your scalp until you feel as though youve cleansed enough, rinse out completely. Feel free to shampoo twice for extra clarifying power. Store the bars on a dish in the shower to allow them to dry, your bars should last you 3+ months, replacing 2-3 plastic bottles.
