Shampoo Instructions:


Get your hair really wet (more wet than you're used to) then rub across your hair 3-6 times. Scrub into a lather.

If you want more lather, you can pop your head back under the water for a second and get it more wet and you'll feel more lather.

Conditioner Instructions:

Apply the conditioner to the really wet ends of your hair. It only takes 2-3 swipes for most people, work into your hair, allow to sit for 2-5 minutes and rinse out.

To refill your SeaBar you simply twist the white Pusher Piece back down to the bottom, and push your Refill in, flat side up.

Customer photo review of REFILL - SeaTree - Tea Tree Shampoo Bar

I've been using Seabar since meeting Greg at the Snohomish Farmers Market in 2025 and I'm never going back!! I have very fine, long, high porosity hair and used to go through A LOT of shampoo, some of it didn't even work well with my hair type or hard well water. This solid shampoo is a huge game-changer. It works great with the hard well water I have to use and my hair and scalp feel so nice! I love not having to replace another big plastic shampoo bottle every month and it makes me feel so happy I get to support a small business that cares so much about the environment! I usually lather and rinse twice until my hair sounds squeaky, then apply the SeaBar conditioner starting from the hairs at neck length all the way down to past my back. I work outdoors in the dirt and heat, so I only space out my hair wash days by one or two days. One of the times when I refilled my SeaBar shampoo holder, I had accidentally threw away the pusher piece, so I emailed Greg and he knew exactly what went wrong and sent me a replacement piece along with my refill!!

Customer photo review of SeaTree - Tea Tree Shampoo & Conditioner Bar Bundle

I was skeptical before I used Sea Bar because I have very thick long hair, but I was pleasantly surprised when I got good lather and coverage from the shampoo and conditioner with only a few swipes of each container. I like using it at home and for travel. Best of all, using Sea Bar helps to keep our planet plastic free.

Customer photo review of SeaTree - Tea Tree Shampoo & Conditioner Bar Bundle

I bought this to replace my normal shampoo/conditioner. I had tried Lush solid shampoo before and been unimpressed. this is such a different product it's not even a fair comparison - SeaBar has made my hair softer and stronger. it's very easy to use in its stick format, has no strong scents that overwhelm me, and leaves my hair and scalp feeling super clean each time I use it.

Customer photo review of SeaTree - Tea Tree Shampoo Bar

I love this shampoo bar! I usually lather rinse and repeat twice and it gets my hair super clean even in hard well water. I wear my hair half up or fully up almost all the time, but when it’s loose it goes down past my butt, so I have a lot of hair to wash. Having a super concentrated shampoo is a game changer compared to cycling through endless liquid shampoo bottles. Thank you, Seabar!

Customer photo review of SeaTree - Tea Tree Shampoo Bar

I love my SeaBar shampoo and conditioner! Since I started using it, my hair is softer and less frizzy. They are also convenient for traveling since they’re easy to pack & no spills!

Customer photo review of SeaTree - Tea Tree Shampoo & Conditioner Bar Bundle

Love the product and the company mission! Will definitely continue to use and also buy for gifts.

Customer photo review of SeaTree - Tea Tree Shampoo & Conditioner Bar Bundle

My hair felt so soft after the conditioner and my flakes are gone!!! Love that it can also be used as a leave in! Hope you come out with a curl cream or gel soon!

Customer photo review of SeaTree - Tea Tree Shampoo & Conditioner Bar Bundle

I’m a dog sitter and travel often and stay at various homes. I found Seabar at a farmers market in Snohomish, WA. It has literally changed my life. I love its “no mess” convenience and it’s a great product. I try to be as environmentally aware as possible. I’m not sure the plastic dome top is necessary as it gets thrown away. It’s way better than the bar shampoos I’ve tried. I’m hoping there will be a bar lotion version one day.

Customer photo review of SeaTree - Tea Tree Shampoo & Conditioner Bar Bundle

The shampoo makes my scalp feel clean and product buildup on my hair gets removed gently. The conditioner does an amazing job de-tangling my hair without being heavy and to much moisture. I will definitely buy more. It also lasts. I am still on my first purchase and used it a lot. I went with the seatree. It smells clean and makes my scalp tingle in a good way. I am very pleased! Thank you!

Customer photo review of SeaTree - Tea Tree Shampoo & Conditioner Bar Bundle

My husband and I really like Seabar. Ie: the mission behind the shampoo and how it actually works for both our hair!

Customer photo review of SeaTree - Tea Tree Shampoo & Conditioner Bar Bundle

I’ve been using Seabar for about 4 years now and nothing compares! I can go longer between washes, I feel cleaner and while I go about 7 months between haircuts, I’m always told my hair is super healthy. Thanks, Seabar!

Love my Seabar shampoo and conditioner - I use the Tea tree ones. My hair feels clean and my scalp feels refreshed. Love how easy it is to use and how un-cluttered my shower is. My hair feels stronger and more balanced now that I’m in the routine of using seabar.

This is such a convenient format, and the tea tree shampoo smells great, doesn't irritate my scalp, and actually cleans my hair! It's my go-to shampoo for travel these days.

I’ve been using this shampoo for over a year now and am so happy to have found it. My hair looks and feels great and no more hair product plastic in the recycle bin! I wish more products were created this conscientiously.

I like this shampoo, it's weird at first rubbing your head with a bar but I really like it.

Love these products! Thanks, Greg and team!

I bought the tea tree scented shampoo and conditioner a few weeks ago to try out on my summer travels. So far it's a huge success! It lathers up great and I really like how it feels. Honestly, my hair feels cleaner than with other shampoos, and silky soft. I have curly/wavy hair, pretty short. More than anything, I really like that it is environmentally conscious, that it makes travel a breeze, and that I can refill the bars at a local store!

This is the first solid shampoo I have tried that works well for me! I like that it lathers and it keeps body in my hair.

I appreciate not having to use bottles for my shampoo.

Love what you are doing for my hair and our planet, you and your products rock!

I love this shampoo and conditioner. It locks in my waves and I literally do not need to do anything after using them. My hair gets compliments all of the time and all I do is wash and go, because of Seabar Before Seabar,y hair was super frizzy. It makes my life easier and the fact that they have fragrance- free options is HUGE! I also likethe tea tree to help keep insects away when I work outside.. the scent is super light but I figure it can't hurt!

Love this stuff!!! Puts that tingle in my dingle and feels so so clean!

I bought SeaBar for traveling. I finally was able to use it. My hair feels fabulous! The conditioner removed all of the tangles and left my hair silky. You have a wonderful product!

Easy to use, good suds, clean

I gave three sets of your shampoo and conditioners to people as holiday gifts. This met several goals: 1. Support small business 2. Environmentally responsible 3. Scents is not intense and doesn’t cause headaches 4. TSA friendly 5. Takes little space in the shower 6. Makes people comment how nice my hair looks

Sea Bar is so easy to use and makes my hair soft and more manageable. I love it!

This product is so great I bought three sets to give as gifts. It saves space, is TSA friendly, I don't react to fragrance, it works amazing on my way hair, my daughters very curly hair and my sons straight hair. It helps to clean the ocean through their trash clean-up pledge and reduces packaging via refills. Also, shipping less water saves on reduced weight which reduces fossil fuel use. The owner is super nice too! It's a win all the way around.

Love that I can feel it working on my scalp. Has a soothing effect on my dry scalp

I have been using Sea Bar for over a year. I tried it because I am determined to decrease the amount of plastic I consume. I continue to buy it because it is a great product. I have long thick curly hair. It is hard to keep healthy. I have had 2 separate stylists tell me how healthy my hair is, even after waiting 6 months for a cut. I would recommend this product to everyone and anyone.

Love that it's solid especially for traveling

In trying to use less plastic, I’ve purchased shampoo and conditioner bars from various suppliers and have been totally disappointed in the way they left my fine hair feeling like straw (looking like it, too!) Sea Bar leaves my hair feeling clean and soft and looking good…thanks for making a product that actually works great!

Love it!! Have been a loyal customer for years

I discovered Sea Bar at a street fair last summer. I was having some irritated areas on my scalp and the shampoo is definitely helping. Plus my hair feels really clean. It would be really nice if you, and other companies, would use different colors or some other way to tell the shampoo and conditioner apart without my glasses on. You do know that lots of people wear glasses to read.

ONG. The best. Shipping is fast. Such good shampoo and conditioner. I am so jazzed about this product.

Great for my old guy gray hair!

I am so impressed! See Bar ticks all the boxes for clean, soft hair and my curls agree.

This is our families favorite brand of shampoo bars and conditioner to use for both straight and fine curly hair!

I was hopeful for the environment but am very unhappy and was going to request a refund. Doesn't lather up enough for my hair and couldn't get the conditioner to untangle my curls (I always use a pick with conditioner in while I am in the shower). I tried it twice and put back in the box - happy to return. I had shoulder surgery, otherwise would have done this a while back. I think the product is a great idea and if recipe gets updated would try again. Thank you
