Ethique Curl-Defining Shampoo Bar — Professor Curl 3.88 oz, Shea & Cocoa Butters for Defined, Frizz-Controlled Curls

Ethique Professor Curl is a solid shampoo bar formulated with shea and cocoa butters to define curls, reduce frizz, and replace multiple plastic bottles.

This concentrated, plastic-free shampoo bar is crafted to enhance natural curl shape while delivering moisture from plant-derived butters and humectants. Lightweight but effective, the bar is vegan and cruelty-free and made to be gentle on color-treated hair. It's compact for travel and built to last—one bar substitutes roughly three standard liquid shampoo bottles, reducing single-use plastic and simplifying your routine.

How does this shampoo bar help my curls look more defined?

The formula focuses on curl structure by combining shea butter and cocoa seed butter with glycerine to lock in moisture and smooth the hair cuticle. That hydration helps strands align and form clearer curl patterns while minimizing flyaways and frizz. Use with gentle scrunching to encourage natural shape.

• Shea butter for rich emollience without weighing curls down
• Cocoa seed butter to add softness and supple texture
• Glycerine to attract and retain moisture for improved curl clumping
• Solid bar format concentrates ingredients for longer-lasting performance

Will this shampoo bar work if my hair is color-treated?

The Professor Curl bar is formulated to be mild and non-stripping so it can be used on color-treated hair when paired with color-safe practices. It avoids harsh sulfates common in liquid shampoos that can fade dye faster. For best results, follow with a color-safe conditioner and cooler rinse temperatures.

• Low-irritant surfactants that cleanse without aggressive stripping
• Moisturizing butters that help protect color vibrancy
• Recommended to combine with a color-safe conditioner bar
• Rinse with cool to lukewarm water to preserve dye longevity

How eco-friendly and travel-ready is this bar?

Each bar replaces about three bottles of liquid shampoo, cutting down significant plastic waste. The solid format is compact, TSA-friendly, and less likely to spill, making it ideal for travel, gym bags, and outdoor adventures. Ethique packages bars in recyclable materials to keep the footprint low from start to finish.

• One bar ≈ three plastic bottles saved
• No liquid restrictions for air travel—easy carry-on packing
• Compact size fits into small toiletry kits and backpacks
• Recyclable packaging and vegan, cruelty-free sourcing

How should I use the bar for best curl results?

Wet hair thoroughly and either rub the bar between hands to create a lather or glide it directly over the scalp for focused cleansing. Massage gently with fingertips, then rinse. For enhanced definition, apply a leave-in or styling product while hair is still damp and scrunch to encourage curl formation.

• Wet hair fully before applying to ensure even lather
• Focus lather at the scalp; let run down lengths to cleanse ends
• Follow with Ethique Curl-Defining Conditioner Bar for best results
• Scrunch damp hair to shape curls, then air-dry or diffuse

Who is this for: Ethique Professor Curl is built for people with naturally curly or wavy hair seeking defined, bouncy texture without excess frizz, and for eco-conscious shoppers wanting to reduce plastic use. It's well suited for travelers, vegans, and anyone who prefers concentrated solid products—especially those with color-treated hair looking for a gentler cleansing option. Pair it with the matching curl-defining conditioner bar to complete a sustainable routine that supports shaped, moisturized curls.
