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.

Love the ease of use. Two swipes and I have my hair full of lather. Great fragrance too! I'll never use liquid shampoos again!

REFILL - Bourbon Cypress Shampoo Bar

I’ve been wanting to try a shampoo bar for quite some time and found Sea Bar at a local craft fair in Port Townsend. After a demo I decided to give it a shot! I love the shampoo and conditioner! I also love that they pick up a pound of sea trash for every sale. I live by the ocean and appreciate knowing there are people out there like me picking up trash on the shoreline. I suggested they reach out to Starbucks my old company to get help because we were always looking for volunteer opportunities. Thank you!

SeaFarer Shampoo and Conditioner Bar Bundle - with DHT Blockers

I’m thrilled with both the shampoo and the conditioner. They both work great! I love that refills are available and I’m not creating new trash for the landfill.

REFILL - SeaFarer Shampoo Bar

I used to buy bar shampoo from Lush and I really liked it, but it would become a soppy mess before I could ever get halfway through. This shampoo bar and conditioner are amazing! The packaging is phenomenal and makes them super easy to use and the product is hair altering - in a good way. My hair was in bad shape, but with a month of washing with Seafarer 2-3 times a week, it looks and feels damage free. I'm losing a lot less hair with each wash, too. I can't recommend enough. My husband is also using it with success and he gives me a lot less grief because there has been a big reduction in the amount of products in the shower.

This conditioner is absolutely lovely. Nice and light and my hair feels soft every time. No more tangly hair, brings out my natural waves.

SeaFarer Conditioner Bar

I love SeaBar! My husband also uses it and loves it. It’s easy to use, vegan and good for the environment. I plan to always use it.

I have two different sets, the Tea Tree was my first and waited a while until I was sure I liked it. It's great. So I purchased this set to go back and forth between the two. I really like the fragrance of this one. I'm pretty sure I won't go back to liquid.

Initially I thought this was just another sales gimmick But after a few uses, I found out this is really a good shampoo. Easy to apply in just a couple of strokes, it lathers up real well and rinsed out easy too. I'm glad I bought sea bar shampoo

Love Sea Bar”s shampoo and Conditioner since we were in Bellingham WA at a festival. Your company’s great philanthropy project is fantastic.

I love the product! Great lather and subtle fragrance. It is so easy to use and perfect for home and travel. I have been telling all my family and friends about it.

The shampoo fragrance is not overpowering, cleans well with out stripping hair. Difficult to use on long hair. Like the idea of using less plastic.

The conditioner works as well as a liquid conditioner. It is easy to work through my hair and does a good job detangling. My hair ends up feeling healthy and soft.

SeaFarer Conditioner Bar

I am super sensitive about my hair because I have male pattern baldness (and I'm a youngish woman). My hair loves the Sea Bar formula. I feel my hair has gotten thicker and stronger and feels very nourished. I haven't been able to find another shampoo and conditioner that does the same for my hair. I also love the size and refillable aspect of the product. I recently traveled with the bars and wow was it convenient! Love that I found it and love the mission of the company!
