See why everyone loves Bar & Bar!
Our bars are formulated with salon-grade ingredients designed to deliver real, noticeable results. Each bar features two targeted active ingredients, carefully selected to address specific hair needs. It’s professional-level performance, thoughtfully concentrated into a clean, bar format.
Color-safe and formulated to prevent premature fading of dyed hair by avoiding harsh surfactants (like sulfates) that strip color, instead using mild cleansers, pH-balanced formulas to seal the cuticle, and advanced UV protectors.
By choosing bars over bottles, the planet will thank you. Each bar saves multiple bottles from ending up in landfills and uses significantly less water to produce. The compact, concentrated format also means fewer emissions from transportation—better for your hair and the environment.

FAQ
How many washes can I get with one Shampoo Bar?
Our Bars are comparable to a 16 oz. size bottle of liquid shampoo.
How do I use a shampoo and conditioner bar?
Shampoo Usage Instructions: Wet hair and bar liberally. Swipe bar from the roots of your hair down to the tips. Swipe bar crossways along front and back hair line, splashing on additional water. Place bar in storage location, then lather your hair as usual using the pads of your fingertips, gently massaging your scalp while splashing additional water on if necessary. Rinse well.
Conditioner Bar Usage Instructions: While hair is very wet, warm conditioner bar slightly under running water for a couple seconds. Swipe bar down lengths of hair thoroughly. Rinse hair very lightly then swipe the bar over the lengths of hair again on any tangled strands, focusing on ends of hair rather than scalp. Allow to sit for 1 minute. Rinse lightly with warm water for more detangling and benefits or rinse thoroughly for a weightless feel.
Will a shampoo and conditioner bar work for my hair type?
Absolutely. Bar and Bar has created targeted haircare bar systems for every hair type and concern. Our Hair Quiz takes the guesswork out of choosing by recommending a Shampoo and Conditioner Bar System tailored to both your primary and secondary hair needs. Most people benefit from more than one system because hair and scalp often have multiple priorities—and our quiz makes it easy to find the perfect match.
How long does one bar last?
This depends on many factors, such as storage conditions, hair type, hair density, frequency of use, etc. To more clearly define this question, however, our shampoo and conditioner bars contain equal active ingredients similar to a 16 oz bottle of a very premium brand liquid shampoo or conditioner.
Will my hair need an adjustment period when switching to bars?
Bar and Bar’s hair systems have been thoroughly tested to be residue-free, however, if you have product buildup from your previous shampoo and conditioner, there may be a short adjustment period, where our luscious lathering shampoo and luxurious conditioner will take a few washes to thoroughly reset the look and feel of your hair and scalp.
Do your shampoo and conditioner bars lather like liquid products?
Yes! Because we are utilizing the exact same ingredients found in a high-end brand of liquid shampoo, the lather feels the same or perhaps better. Also, our bars have been tested against other bar brands currently on the market and ours had superior in-lab foam-tests than the cheaper bar brands. The conditioner bar is far more concentrated and just a few swipes and an extra splash of warm water create a luxurious creamy feel on the hair.
Are Bar & Bar products safe for color-treated or chemically treated hair?
Our bars are free from sulfate detergents and have been formulated with the mildest cleansers on the market suitable for color-treated hair. Also we have carefully pH balanced and added nourishing ingredients that actually assist slowing the fade of hair color and treatments.
Are your bars drying or stripping?
Not at all. We’ve tested our bars against every major bar brand on the market, and feedback from hundreds of testers shows their hair felt more nourished, silky, and shiny compared to others. Even our Clarify + Balance shampoo and conditioner — formulated for oily hair — is designed to cleanse without stripping. Instead of triggering excess oil production, this set supports the scalp’s microbiome and helps rebalance the sebaceous glands over time for long‑term oil control.
