    Great shampoo bar

    I like this shampoo bar! It was my first time trying out shampoo in a bar, and it was a nice, smooth and easy experience. The foam is generated easily, so it reminds a usual hair washing with a liquid shampoo. The bar stays whole and lasts for a long time. The smell is great and creates a pleasant washing experience — like aromatherapy. And, as a bonus, it stays on the hair for a while. The only drawback that I’ve noticed is that without a conditioner, hair feels dry after washing, so maybe that can be improved a bit. As a recommendation to the users to lessen that effect, maybe try washing the roots rather then all the length. I do like the cleaning power though — it is noticeable if you have a long week. So thank you for this product :)

    Great Smell

    You inhale the most wonderful scents from this shampoo. I can't yet tell if my hair is less dry, and I wouldn't know if the shampoo or the conditioner were the cause of an improvement, but the scent and price are great.



    Hi there! Thank you so much for such positive feedback! We really hope that you continue to enjoy your haircare routine with our products :)

    It’s softer than most shampoo bars, therefore it lathers easier. A much more pleasurable experience all round.

    Frequently Asked Questions

    How does solid shampoo work?

    Solid shampoo is different from liquid shampoo because it is made of a solid state instead of a liquid. Its texture makes it easy to transport and use, but its unique properties also make it better for the environment.

    Solid shampoo bars are biodegradable and can be used without any wastewater
    or chemicals being produced during the washing process. They are also good for your wallet: not only do you save money over time with fewer bottles to buy,
    but they're less expensive than liquid shampoos as well!

    How to care for dry hair?

    Is your scalp itchy and flaky? You have dry hair. Avoid volumizing shampoo, which will remove moisture from your scalp. Go with products that promote moisture retention and work well for curly hair. Sulfates are not your friend either, they’ll dry out your scalp.

    Why is Bam&Boo’s Dry Hair Shampoo better than the others?

    Our Shampoo Bar was made specifically for dry hair as it brings vitality to your hair by replenishing the oils lost at the hands of chemical-based shampoos. Both açai and olive oil are full of nutrients that will fully moisturize while strengthening your hair.

    Does it clean the hair as effectively as traditional liquid shampoos?

    Yes. What makes our solid shampoos effective? 

    They deliver powerful cleansing without being harsh on your hair.They have nourishing ingredients that are safe even for long-term use.They are formulated with balanced pH levels and humectants for healthy, moisturized hair.

    The absence of chemical additives, SLES,
    sulfates, and parabens makes them a better alternative to most liquid shampoos
    as well.

    There is, however, a learning curve with shampoo bars. Some users say there is a transitional period when hair feels waxy and heavy, but these effects are usually temporary.

    Curly and long-haired consumersmay notice more frizz and tangles created by the action of rubbing hair with the bar.
    This, however, can be addressed by making a lather with your hands and massaging the hair gently.

    How long does it take your hair to adjust to bar shampoo?

    Cleaning without harsh chemicals will cause your scalp to rebalance its oil production. Many say the transition period lasts around 2-4 weeks.

    Will my hair look different when I use solid shampoo?

    Solid shampoo is a different experience, but it cleans your hair just as well. You may need to get used to it. If you are worried about how your hair looks after using solid shampoo, try a small batch first and see if it works
    for you. If so, then go for the full size!

    We run a transparent "Satisfied or Refunded" policy. If somehow
    you don't like the experience we will refund your money on the purchase of the solid shampoo.

    How often should you use a shampoo bar?

    Try not to use shampoo every day, as washing too frequently can strip the hair, leaving it brittle and prone to breakage. Aim to wash every other day at the most, or wait a few days between shampoos if you're able.

    Is solid shampoo more expensive than traditional liquid shampoo?

    By unit yes. By use no.

    Each bar of solid shampoo lasts about the same as 2-3 bottles of regular liquid shampoo.

    This is because a shampoo bar is a very concentrated and dehydrated product. In a package of regular liquid shampoo, up to 80% of its composition is water.


    It is important to compare the cost per use: Solid Shampoo vs. Liquid Shampoo.

    On average one bar of solid shampoo lasts for 70 uses. For a unit price of 10.90€, the cost per use is 0.16€. Or 0.12€ if you choose the subscription option. In comparison, the average price of regular liquid shampoo is 3.99€ (250ml package) and will last approximately 25 uses. Therefore the cost per use is 0.16€.

    So the price per use of a shampoo bar is equal to or less than that of liquid shampoo.


    How much shampoo you need depends on a lot of factors. Hair amount and hair texture are two of the biggest factors that change how much shampoo you'll need. You need to try and compare what works better for you.
