Reviewers at NBC Select, TheRoundup, and sustainability-focused outlets like ImPlasticFree consistently highlight a handful of criteria that separate genuinely plastic-free bath and body products from greenwashed alternatives: compostable or paper-based packaging, clean ingredient lists free of parabens and synthetic preservatives, and formulas that actually perform as well as their conventional counterparts. Below are the specific products that surface repeatedly in expert coverage and consumer reviews as strong picks across the core categories of a plastic-free bathroom routine.

1. Lush Honey I Washed My Hair Shampoo Bar

This circular shampoo bar from Lush is one of the most frequently cited solid shampoo options in expert roundups. Formulated with honey, bergamot oil, and Brazilian orange oil, it cleanses, moisturizes, and softens hair while delivering a sweet honey and toffee scent. According to NBC Select reporter Zoe Malin, it "fit perfectly in the palm of my hand and was easy for me to turn into a lather that I transferred from my hands onto my hair." Each bar is equivalent to roughly three bottles of liquid shampoo and lasts an estimated 60 to 80 washes.

Why it stands out: NBC Select editors tested this bar and noted its reliable lather and softening results. It ships in Lush's signature minimal, plastic-free packaging, and the concentrated formula means far less waste per wash than a conventional bottle.

Things to know: The honey and toffee scent is distinctive and may be too strong for those sensitive to fragrance. It is priced at around $15, which is competitive for a bar that replaces multiple bottles.

2. Hibar Moisturize Shampoo Bar

Hibar makes shampoo bars specifically engineered to mimic the feel and performance of liquid shampoo, which makes them a popular gateway product for people new to solid hair care. The Moisturize bar is formulated for dry hair and uses a syndet (synthetic detergent) base rather than traditional saponified soap, which keeps the pH closer to skin-neutral and reduces the adjustment period many people experience when switching to bar shampoo. It is widely available on Amazon and at major retailers, making it easy to find in the US market.

Why it stands out: NBC Select identifies this as a strong pick for dry hair, and its syndet formulation is noted by hair care experts as gentler on the scalp's acid mantle than traditional alkaline soap bars. The packaging is entirely plastic-free cardboard.

Things to know: Priced at around $14, it is one of the more affordable options on this list. Because it uses synthetic surfactants rather than saponified oils, it may not appeal to those seeking a fully natural or oil-based formula.

3. Ethique Curl Defining Solid Shampoo Bar

Ethique, a Certified B Corporation based in New Zealand with strong US availability, built its reputation on plastic-free beauty long before it became a mainstream trend. This square shampoo bar is formulated with shea butter, cocoa seed butter, and glycerin to gently cleanse while defining curls and reducing frizz. It carries a 4.6-star average rating from over 400 reviews at Ulta and is designed for curly, wavy, and coily hair types. All Ethique packaging is plastic-free, compostable, and recyclable.

Why it stands out: Reviewers at NBC Select and Ulta shoppers consistently praise its frizz-reducing results and lather quality. It is safe for color-treated hair and pairs with a matching Ethique conditioner bar for a fully plastic-free wash routine. TheRoundup also highlights Ethique's broader brand commitment, noting the company donates 2% of yearly revenue or 20% of profit to eco-friendly charities.

Things to know: At $17, it sits at the higher end of the shampoo bar price range. The lemongrass scent is pleasant but noticeable, so those with fragrance sensitivities may want to seek out an unscented alternative.

4. Native Plastic Free Deodorant

Native is an established US deodorant brand, and its Plastic Free line swaps the conventional plastic stick for a paperboard tube sourced from responsibly managed forests. According to ImPlasticFree, the brand estimates that switching from its classic packaging to the plastic-free version reduces plastic waste by up to 169 tons per year. The formula is aluminum-free, paraben-free, vegan, and cruelty-free, and it is made in the USA from naturally derived ingredients. It is available in a wide range of scents including Coconut and Vanilla, Lavender and Rose, and Cucumber and Mint, as well as an unscented option.

Why it stands out: ImPlasticFree notes that Native Plastic Free has earned over 50,000 five-star reviews, making it one of the most validated plastic-free deodorants on the market. The brand is also a member of 1% for the Planet, donating 1% of purchases to environmental nonprofits.

Things to know: Like all baking-soda-based natural deodorants, it may cause irritation for people with sensitive underarm skin. Those prone to reactions should look for a baking-soda-free formula or patch test first.

5. Meow Meow Tweet Zero Waste Deodorant Stick

Meow Meow Tweet is a small-batch, independently owned brand that has become a favorite in zero waste circles for its straightforward approach to natural deodorant. The stick comes in a paper tube that is both recyclable and compostable, and the formula relies on baking soda, magnesium, and arrowroot to absorb moisture and neutralize odor. TheRoundup's James Miller, who has personally tested over 300 eco-friendly home products since 2018, describes it as "a seriously powerful sustainable deodorant all wrapped in a zero-waste tube" and notes it is a household staple.

Why it stands out: TheRoundup rates it highly for scent longevity (12 to 18 hours) and notes that all Meow Meow Tweet products are 100% cruelty-free, vegan, and palm oil free. The Lavender Bergamot scent is particularly well-reviewed, though an Eucalyptus Lemon option is available for those who prefer a lighter fragrance.

Things to know: At around $14 for 1.8 oz, the cost per ounce is higher than mass-market options. The baking soda content means it may not suit very sensitive skin. Application requires a light touch to avoid applying too much.

6. WhollyKaw Bare Naked Prebiotic Bar Soap

For body cleansing, bar soap is consistently identified by experts as the more sustainable format. As the team at WhollyKaw explains, bar soap uses minimal packaging (often just paper), weighs less per use because it contains no added water, ships more efficiently per gram of cleansing, and produces significantly less plastic waste than liquid soap in a pump bottle. The Bare Naked Prebiotic Bar is unscented, formulated for sensitive skin, and designed to support rather than disrupt the skin's microbiome. It is suitable for both body and face use.

Why it stands out: WhollyKaw's detailed comparison of bar soap versus liquid soap notes that bar soap is consistently cheaper per use, with a typical bar lasting 30 to 45 days of daily showering. The prebiotic formulation is a meaningful differentiator for those concerned about surfactant-driven microbiome disruption, a concern that applies equally to harsh liquid soaps and harsh bar soaps.

Things to know: Traditional saponified bar soaps have a naturally higher pH (7.5 to 10) than skin's surface pH of around 5.5, which can temporarily affect the acid mantle. WhollyKaw notes this disruption is temporary, but people with very sensitive or compromised skin may prefer a syndet bar formulated at a lower pH.

7. J.R. Liggett's Traditional Shampoo Bar (Tea Tree and Hemp Oil)

J.R. Liggett's has been making traditional bar shampoos for decades and is a popular recommendation for people dealing with scalp concerns like dandruff, dryness, or dermatitis. The Tea Tree and Hemp Oil bar uses antiseptic and antibacterial ingredients including tea tree oil, hemp oil, and olive oil to reduce itchiness, retain moisture, and manage flaky scalp conditions. It is fragrance-free and comes in minimal, plastic-free rectangular packaging. On Amazon, it carries a 4.2-star average rating from over 14,000 reviews.

Why it stands out: NBC Select highlights this bar for its scalp health benefits, noting that reviewers praise its sudsy lather and clean feel after washing. The plastic-free packaging and absence of added fragrance make it a strong pick for those with sensitivities or scalp conditions.

Things to know: Priced at around $13 on Amazon, it is one of the most affordable options in this category. Because it is a traditional saponified bar rather than a syndet bar, it has a higher pH, which some users find drying with frequent use. Pairing it with a conditioner bar can help offset this.

How to Choose the Right Plastic-Free Bath and Body Products

• Check the packaging first: True plastic-free products use compostable cardboard tubes, paper wraps, aluminum tins, or glass jars with metal lids. Watch for products that claim sustainability but still use plastic shrink wrap or boxes with plastic linings.
• Read the ingredient list: ImPlasticFree and TheRoundup both flag aluminum compounds, parabens, triclosan, propylene glycol, and synthetic fragrances as ingredients worth avoiding in natural deodorants and body care products. For shampoo bars, look for hydrating ingredients like glycerin, natural oils, and shea butter suited to your hair type.
• Match the formula to your hair or skin type: NBC Select experts emphasize that shampoo bars are not one-size-fits-all. Dry or curly hair benefits from bars with shea butter and cocoa butter; fine or sensitive scalps do better with lighter formulas containing peppermint or rosemary; scalp conditions like dandruff call for antiseptic ingredients like tea tree oil.
• Consider syndet bars versus traditional soap bars: Syndet (synthetic detergent) bars are formulated at a pH of 5.5 to 7 and are gentler for daily use, especially on the face or sensitive scalp. Traditional saponified bars run more alkaline but are often simpler in ingredients and free of synthetic preservatives.
• Factor in cost per use, not sticker price: WhollyKaw's analysis shows that bar formats consistently outlast their liquid equivalents per gram of product, often by two to three times. A $15 shampoo bar that replaces three bottles of liquid shampoo is a better value than it appears at first glance.

The single most important shift in building a plastic-free bath routine is choosing concentrated, solid formats wherever possible. Bars and sticks eliminate the plastic bottle entirely, last longer per use, and are increasingly available in formulas that match the performance of conventional liquid products. Starting with one swap, such as a shampoo bar or a paper-tube deodorant, makes the transition manageable and the results easy to evaluate.
