Named "The Best Shampoo Bar for the Dandruff-Prone" by (formerly Gentlemen's Quarterly magazine) in September 2023.

Our 2% Pyrithione Zinc Fragrance-Free Dandruff Shampoo Bar controls and reduces the symptoms of dandruff and seborrheic dermatitis but without the plastic bottle. The premium formulated plant-based ingredients lather big and rinse well. This gentle Pyrithione Zinc OTC medicated dandruff shampoo bar gives liquid counterparts a run for their money. It's 100% soap-free and uses pyrithione zinc, argan oil, and oat flower to treat scalp issues.

  • Sulphate Free
  • SLS Free
  • MPG Free
  • PEG Free
  • Paraben Free
  • Preservative Free

Help rid the earth of plastic shampoo bottles by switching to a solid dandruff shampoo bar. This bar is quite different from our other dandruff shampoo bars - it is extruded and stamped as opposed to poured and cut. The premium formulation has a bigger lather and works in soft- and hard-water of all pH levels.  This bar will outlast multiples bottles of liquid shampoo. 

This is a non-soap formulation (known in the industry as syndet).  The pH of this bar is 5.2.  The optimal pH value of skin on most of our face and body lies between 4.7 and 5.7.  The bar is fragrance-free and has a difficult-to-describe SCI smell (a mild natural odor) that will not linger after use. 

Pyrithione Zinc is not your only option.  We also make a Sulfur & Salicylic Acid Dandruff Shampoo Bar.


4 OZ - 3" x 1" Puck Shaped - Single Bar Per Box


Use on affected dandruff or SD areas in place of your regular shampoo.  For best results use at least twice a week or as directed by a doctor.  Rub between hands to create a lather, or apply directly onto hair. Massage into the hair and scalp for 60-90 seconds; then rinse well.

You may follow cleansing with the natural conditioner of your choosing.


Some people are sensitive or allergic to zinc pyrithione. A mild tingling or burning sensation is not uncommon at first use and usually subsides  with continued use. If you experience a severe burning sensation you should discontinue use. The zinc bar is for external use only.  Ask a doctor before use if you have a condition that covers a large area of the body.  When using this product avoid contact with eyes.  If contact occurs, rinse eyes thoroughly with water.  Stop use and ask a doctor if condition worsens or does not improve after regular use as directed.  Keep out of reach of children.  If swallowed, get medical help or contact a Poison Control Center right away.


2% Pyrithione Zinc


Sodium Cocoyl Isethionate (SCI): Known as Baby Foam due to its exceptional mildness, SCI raw material is a surfactant that is comprised of a type of sulphonic acid called Isethionic Acid as well as the sodium salt ester from Coconut Oil.
Stearic Acid: A vegetable derived waxy substance used as a thickening agent in shampoo bars. 
Coconut Fatty Acid: A surfactant, cleansing agent, emulsifier and a foam booster.
Sodium Isethionate: 
An organic salt isethionic acid that was discovered in 1833. It is used as an organosulfur compound. It lowers the pH while maintaining a high level of detergency and lather.
Coco Glucoside: A natural, gentle, and environmentally-friendly cleansing agent and surfactant (a word that is the shortened version of the term “Surface Active Agent”) sourced from coconuts. Sufactants prompt oil and water to combine, thereby making it easier for oily residue found on the hair to attach to syndet (synthetic detergent) and water, leaving the hair cleansed of any grease without stripping away its natural oils.
Soyethyl Morpholinium Ethosulfate: a soy-derived natural odor control used to neutralize the unpleasant smell of SCI.
Cetearyl Alcohol & Ceteareth-20: A self-emulsifying, non-ionic cream with emulsification properties. An emulsifier is capable of dispersing one liquid into another immiscible liquid. This means that while oil (which attracts dirt) doesn't naturally mix with water, soap/shampoo can suspend oil/dirt in such a way that it can be removed.
Sodium Methyl 2 Sulfolaurate & Disodium 2-Sulfolaurate: A natural food grade emulsifier and mild non-drying cleanser derived from coconut oil.
Argan Oil: Often referred to as “liquid gold,” Argan Oil comes from the Moroccan Argan Tree (Argania Spinosa) and has long been used to soften, soothe and moisturize skin and hair. It is made from the kernels of argan fruit.
Oat (Avena Sativa) Flour
Sucrose Cocoate: A natural chemical ingredient sourced from coconuts. Sucrose Cocoate is a hydrophilic emollient, meaning that it absorbs water and can help to balance or maintain moisture. It is also has a thickening effect, and can increase the density of foam.
Tocopheryl Acetate (Vitamin E)
Sodium Isostearoyl Lactylate: A sodium salt of the isostearic acid ester of lactyl lactate. It adds excellent feel to detergent and emulsion systems. It is also substantive to skin and hair and is hygroscopic (absorbing moisture from the air). It has multiple functions: emulsification, conditioning, hair repair, and moisturization.
Iron Oxides (Yellow Ochre): A mineral colorant.


Made in the USA of U.S. and imported ingredients.

Works! Lessens dandruff, and it's solid

Got this because my partner is sensitive to the scent of other anti-dandruff shampoos. She doesn't notice this, and it does the same job that Head & Shoulders does. Also I can travel on planes with it. Awesome! BEWARE, this stuff is SUPER dense! You don't need much for each treatment. It lathers really well. The only downside for me is that it kinda burns and dries out the skin. So be sure to follow it with a good conditioner.

Literally squeaky clean hair

Lathers great, no dandruff, and rinses easily. I really like this because it doesn't have a lot of ingredients in it and when all the suds are rinsed out of your hair your hair actually squeaks. This also doubles as a face wash.

Really nice lather and it works

I have been looking for a replacement for my plastic bottle anti dandruff shampoo for a while and one with no scent and I was so happy to run across this. I've used it a few times now since it arrived and my hair looks great and feels great and I think im seeing a bit less hairfall as well and definitely less itchiness in my scalp. The bar makes a fantastic lather, better than any other bar shampoo i've had. If you are looking to eliminate more plastic waste in your life - this is a great product.


Ive tried all the different types of medicated shampoos off the shelves and this is one of the only that helps eliminate flakes.


Cleans very well, will last ages! Bit drying son, I'll use it every other wash. Thanku!

A stand out

Over the years, we have tried countless shampoos to alleviate a number of scalp issues. This shampoo really stands out in a crowd. Both of my teenagers absolutely love this shampoo and getting them to agree on anything is close to impossible. It has completely cleared up the relentless dandruff and reduced the itching from endless eczema. It’s a little too strong for my needs so I will stick with my current shampoo, but I will continue to order this for my family.

My hair is thick type 3&4 kinky curls. I always get really bad dandruff flakes and scalp dermatitis around my hairline but after one use I saw waaay less flaking. Usually I’d use head & shoulders shampoo but it would irritate/burn my scalp and the flaking wouldn’t subside. But THIS soap is definitely 10/10
