"This bar shampoo is a game-changer. The shampoo left my hair soft and rinsed out cleanly."

Jen Lee, New York City, NY


Copious Creamy Lather

Herbaria Shampoo Bars gently and thoroughly cleanse your hair and leave it soft, shiny, and easy to manage.

All-Vegetable Goodness

Our Shampoo bars are handmade in small batches with moisturizing, food-grade vegetable oils. Rich emollients, like jojoba oil, sunflower seed oil, and argan oil, keep your hair and scalp healthy.

Herbaria shampoo

Herbaria Quality

The oils with which we make our shampoo are similar to our bar soaps in that they are all food-grade vegetable oils. However, the formulation is quite different for hair.


Commercial shampoos contain primarily detergents and synthetic surfactants. They tend to strip hair of its natural oils and make conditioners a must. With these moisturizing shampoo bars, hair and scalp maintain a natural balance. Conditioners are typically unnecessary. 

No Plastic Bottles

Good Basics

Our Shampoo bars clean and condition hair with a combination of oleic, linoleic & linolenic acids, achieved by combining rapeseed oil with other oils. Castor oil is celebrated for its nourishing properties for skin and hair. Coconut oil cleans your hair flawlessly and adds oodles of bubbles to the lather. Sodium lactate hardens the bar and, as a humectant, draws moisture to your scalp and hair, adding moisture without greasiness. Sodium lactate does not contain milk protein and need not be restricted by someone avoiding milk or those with a milk allergy. Our shampoos are vegan, like all of our products.

No Bad Stuff

Our vegan shampoo bars contain no synthetic fragrance, dyes, phthalates, or formaldehyde. Our bars are free of petroleum-derived detergents such as sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES). Those harsh chemicals can cause dryness, itching, and irritation. Unlike liquid shampoos, bars need no questionable preservatives. People with allergies, dandruff, and eczema may benefit from our shampoo.

Shampoo Bars

Two Formulas

Finer Hair Formula lathers up nicely and moisturizes hair, making it soft without weighing it down. High oleic sunflower oil in the bar leaves hair luminous.

Thicker Hair Formula creates abundant lather that moves easily through the hair and gets through to the scalp. Your hair will feel lighter and easier to style. The Thicker Hair Formula contains added jojoba oil and argan oil. It's good for curly, wavy, coarse, and afro-textured hair.

Not sure which to choose? Take your best guess and give it a try. If you're not happy with the results, we'll happily supply you with the other formula or, as usual, your money back.

Four Fabulous Scents

Citrus  •  Lavender  •  Rosemary Mint  •  Tea Tree

All aromas are tempting, coming from pure essential oils. For visual identification of varieties, we use only natural colorants.

Each scent is available in either formula, for Finer Hair or Thicker Hair.


Citrus Shampoo


Citrus scents burst from key lime, bergamot, and lemongrass. Ylang-ylang, clary sage, and juniper essential oils make it extraordinary! Annatto is the natural colorant.




Just about everyone loves lavender, especially if we're talking about the essential oil of lavender. With its floral, herbal aroma, lavender has been used and adored for centuries. Alkanet root provides the pale purple color.


Rosemary Mint Shampoo

Rosemary Mint

Here's a blend of healthy and invigorating essential oils. Rosemary nourishes the scalp and hair. Peppermint stimulates, cools, and pairs perfectly with rosemary. A bit of dried, powdered parsley makes it green.


Tea Tree Shampoo

Tea Tree

If you have had any scalp issues such as dandruff, itchiness, or dermatitis, try this shampoo bar. This blend of herbal essential oils features Australian tea tree, renowned for supporting healthy hair and scalp. Clary sage, geranium, lavender, and eucalyptus create a unique, rich aroma and are also said to be beneficial. Green tea colors the bar tan.


Vinegar Rinse

If you have hard water, an apple cider vinegar rinse will help remove any shampoo left in the hair. To make an apple cider vinegar rinse, pour ¼ to ½ cup of apple cider vinegar in a 16-ounce bottle and fill with water. Pour the solution through your hair after you've rinsed all the shampoo out. Leave it for a minute, then rinse lightly. The rinse works like magic and makes your hair lustrous.

"Wow! What lather! What a wonderful scent (I chose the lemon), and best of all? My hair was so soft and fed oils that they put in their soap with it plus (this is an old fashion rinse for hair, but boy does it work: 1/4 c vinegar (I use apple cider vinegar) in 1 cup of water....use that as a rinse and your hair is going to feel like silk.

"Anyway...I grew up washing my hair with a bar of soap and vinegar this is like going back to those times. My hair is much happier now. I dislike shampoos that read like a chemical dump. I just don't want chemicals absorbed into my scalp (and they are). Instead, with Herbaria's hair soap, all you get are natural oils that are good for your scalp and feed your hair."

Lindsay McKenna, bestselling author, from her Facebook page

Safe for Color-Treated Hair

These bars won't strip color-treated hair. Use Herbaria Shampoo bars to revitalize hair that's been over-processed from straightening treatments, heat styling, and extensions.

"I love Herbaria's Shampoo Bars!! They last so long, and it's so nice that I don't even have to use conditioner! Plus, they smell SO great."

Brittney Huck (from our Facebook page)

"Been using the bars for a couple of months now: work great, leave hair clean, and the scalp feeling wonderful. All the plastic bottles I did not is an added bonus. Highly, highly recommended."

Regine Nickel (from our Facebook page)

"I am this Yelper's wife and am rating the only product I tried: Citrus bar shampoo for fine hair. I got a free trial bar after wandering into the store while in The Hill neighborhood. I'd never heard of Herbaria before. I was very skeptical that a bar of soap would work on my colored, fine, straight hair, but it was free (and unusual), so I gave it a whirl. Normally I spend $$$ on salon-grade liquid shampoos. I'd never considered that liquid shampoos are primarily water, detergent, and other chemicals. I am a convert! Using this bar shampoo was the ONLY change in my hair regime, and I'm so glad I stumbled upon it. My hair now has body and life and looks smooth and healthy. I've received compliments from family and friends. Thank you, Herbaria, for making this wonderful bar shampoo product. I will be returning to buy more."

Two More Benefits of a Bar Shampoo

No plastic bottles to add to the Earth's pollution. 

No liquid to pass through TSA security screening. Shampoo bars can go in carry-on luggage.

How to Shampoo Your Hair with a Bar

  1. Wet the hair thoroughly.
  2. Rub the bar over your hair in a combing motion. Alternatively, lather up the bar in your hands and work the lather with your fingers through your hair like a comb.
  3. Massage lather into hair and scalp. Keep working up a lather. Add more water if necessary.
  4. Rinse very well.
  5. Repeat if you like.
  6. Dry your hair without causing tangles. Comb your hair from ends upwards.

Longer hair?

If you have long hair, try putting the lengthy part in a ponytail and shampoo the hair and scalp area above the ponytail. Then, take out the ponytail, rinsing the soap out through the rest of your hair. Make sure you rinse well.
