Shampoo and conditioner bars have elevated the sustainable hair care game. Since we last tested these plastic container-free alternatives, we have noticed that they’ve evolved and expanded to address everything from dryness to brassiness. Plus, the bars deliver up to 100 washes without cluttering your shower. With formulas that tackle a range of hair concerns, we’ve rounded up the best of the best.
Best for damage repair:
- Kitsch Strengthening Solid Shampoo, $14
- Kitsch Strengthening Solid Conditioner, $14
- Kitsch Strengthening Bond Repair Solid Treatment, $19
When it comes to repairing and protecting your hair, these three bars will be your go-to for revitalization. Start with the Kitsch Strengthening Solid Shampoo, which balances pH and uses rice water protein to mend damage. It prevents split ends, promotes hair growth, and leaves your hair soft and shiny—all while saving two plastic bottles per bar.
Follow up with the Kitsch Strengthening Solid Conditioner, infused with rice water protein and essential oils to rejuvenate damaged follicles, smooth split ends, and enhance the shine of dull, dry hair.
The Kitsch Strengthening Bond Repair Solid Treatment is a weekly essential for restoring life to dry hair. Enriched with a vegan keratin-like protein and marula oil, it seals the cuticle, deeply nourishes, and locks in moisture. Use it once a week for ten minutes to experience the transformative effects.
Best for combatting dullness:
- Kitsch Clarifying Solid Shampoo, $14
Designed to breathe new life into lackluster strands, this salon-quality bar delivers a deep clean that removes buildup and excess oil that causes dullness, without stripping your hair of its natural moisture. Infused with refreshing tea tree and mint essential oils, it leaves your hair feeling revitalized and your scalp invigorated. This clean provides the perfect base for your styling routine, ensuring your hair looks its shiniest.
Best for restoring moisture:
- Christophe Robin Hydrating Shampoo Bar with Aloe Vera, $22
- Kitsch Deep-Moisturizing Solid Conditioner, $14
Parched strands will drink up the benefits of these two bars. The Hydrating Shampoo Bar blends aloe vera, natural glycerin, and castor oil to gently cleanse while infusing moisture, leaving your hair vibrant and refreshed. Pair it with the Deep-Moisturizing Conditioner, enriched with coconut oil, cocoa seed butter, and shea butter to soften, strengthen, and add shine to dry, brittle hair. Essential oils like lavender and orange enhance the experience, ensuring your hair stays deeply nourished and smooth.
Best for reducing skin irritation:

Sensitive scalps, your search for a gentler shampoo ends here. This 2-in-1 bar is perfect for those with skin and fragrance sensitivities, offering a soothing cleanse for both hair and body.
