The Earthling Co. shampoo and conditioner bars are solid, water-free versions of liquid hair care. You rub the bar directly on wet hair — the shampoo lathers and cleans, and the conditioner re-coats the cuticle on mid-length to ends. Formulas are sulfate-free, paraben-free, and phthalate-free, and each bar lasts roughly 80 washes, replacing about 2 to 3 standard 12-ounce plastic bottles. Liquid hair care is typically 70–80% water; removing the water shrinks packaging, lowers shipping emissions, and eliminates the plastic bottle entirely. The Vanilla Coconut Shampoo & Conditioner Bar set was the first shampoo-and-conditioner bar system to undergo a clinical study, with measurable gains in shine, manageability, and reduced breakage versus a leading liquid competitor.

Wet your hair and the bar, then glide the shampoo bar directly onto your scalp. Massage into a rich lather and rinse. For conditioner, glide the bar along the lengths of your hair, let it sit for a few seconds, then rinse thoroughly.
Most people notice improvements quickly, but results build over time. Here’s a general timeline:
After the first few washes: Hair feels cleaner, lighter, and free of buildup. Many also notice improved softness and scalp comfort.
Within 2–3 weeks: Increased shine, smoother texture, and better overall manageability as your hair adjusts to the cleaner, more nourishing formulas.
By 4–6 weeks: Reduced breakage, less shedding, and stronger, healthier-feeling strands.
By 8–12 weeks: Full results — hair looks visibly healthier, fuller, and more resilient with consistent use.

IMPRESSED IS AN UNDERSTATEMENT
On my first wash, I noticed a huge difference. My hair felt soft and supple like I had just gone to the hair salon. It normally feels heavy and tangled, but it has been amazing!
