The shea butter and coconut oil in this bar can help zap some life back into your hair. A 2005 study found that coconut oil is particularly good at penetrating hair fibers to help quench dry locks.

Considerations: If you’re sensitive to fragrance, this one may not be for you. You may also want to go a little longer between washes if your hair is limp. This lets your locks build up natural oils without overdoing it with the shampoo.

No.313 - Prevent Acne

Overwashing your hair or using shampoos packed with chemicals can strip away natural oils. This makes your scalp work overtime and produce excess sebum. Ethique’s St. Clements shampoo bar uses citrus oils and castor oil to remove excess oil without overstripping your hair. It also features vegetable glycerin to help moisturize without making your hair oily.

Considerations: Some reviewers don’t love this bar for colored hair or dandruff. And while it’s free of the typical sulfates, it does use the less processed sodium coco sulfate (SCS) for a lather.

Rating: 4.9 starsReviews: 1,530+ on The Earthling Co.Price: $$

Lots of shampoo bars contain natural oils, but The Earthling Co. takes it to the next level with no sodium laurel sulfate (SLS), silicones, parabens, or preservatives.

The bars come in a ton of different oil blends and scents, but all use lemon oil to remove buildup and cocoa butter and coconut oil to moisturize. You can calm down with lavender vanilla or have a morning pick-me-up with citrus sun. There’s also an unscented shampoo bar if that’s your thing. Plus, some of the bars claim to last 50 to 70 washes!

Considerations: Different scents vary in size, so depending on the scent you prefer, you might not get the full 70 washes. Some reviewers also find certain scents too strong.

Rating: 5 starsReviews: 1,869+ reviews on EtsyPrice: $

The “no-poo” method means ditching products that contain the typical shampoo chemical additives. This bar contains apple cider vinegar (aka ACV), which is one of the more popular no-poo options. This all-natural bar cleanses hair without harsh ingredients and is an affordable way to dip your hair into the no- poo waters.

Considerations: The seller warns that because the natural ingredients don’t strip out natural oils, your hair may need a 3-week transition period to get used to this bar.

The Yellow Bird has several all-natural shampoo bar options, but the Grapefruit Rosemary Lavender bar is a fave for folks with flaky or sensitive scalps. It just sounds soft and gentle, right? An added perk: Rosemary has antimicrobial properties that might help with dandruff.

Considerations: Although you can use this bar on oily hair, some reviewers say it doesn’t work for theirs. Your hair will also need to get used to the natural ingredients.

How to use a shampoo bar

Shampoo bars are easy (and even fun!) to use. Here’s how to get sudsy with a shampoo bar:

  • Wet your hair thoroughly.
  • Rub the shampoo bar directly against your hair or scalp.
  • Lather, rinse, repeat (as needed).
  • Follow up with a conditioner if that’s part of your routine.
  • Store the shampoo bar in a dry place (not in your shower or tub). Bars usually last longer this way.

Choose your ’poo wisely

First, congrats on making the commitment to reduce plastic waste. That’s a really big step! Shampoo bars are just as good as (if not better than) bottled shampoo. It might take some trial and error, but you’ll def find the shampoo bar of your best-hair-day dreams!
