  • Greasy hair can be a bit of a faff! That’s why we carefully chose Olive Oil and Charcoal as our primary ingredients, to help cleanse the scalp while hydrating the hair.

    The Olive Oil will help soften your hair while the Charcoal present in the formula helps cleanse impurities, draws the sebum and clarifies oil buildup. This leaves the skin on the scalp free and lets your hair breathe at the root, thus promoting hair growth.

    ​​Handmade in Portugal in small batches, mostly using local raw materials. Organic Olive Oil is a key component of our shampoo bars sourced from local artisan producers, as well as some of the Essential Oils we use.

    Made in Portugal.

    Like the product, but the price is out of my reach

    Like the product very much, though not sure it'll last long. Also, the pricetag is out of my reach, unless it lasts longer than 4 months (which is what the equivalent in my fructis shampoo lasted - 2 shampoos, matching the price of one bar of Bam & Boo).

    SHAMPOO BAR | Oily Hair

    Doesn't lather a lot so it's slightly harder to apply but still really satisfied with the purchase because it leaves the hair smooth and silky.

    Great purchase!

    At first I was reticent about using this type of shampoo but i decided to give it a chance and I really dont regret it. My hair looks really clean, shiny and soft. I wish the smell would be a bit stronger after drying my hair but still, it's a good smell. It's good to know that now there are healthier hair shampoos we can use and I highly recommend this one!



    Hi Hélène, This is truly incredible! We're so happy to hear that you've had such a positive experience with our shampoo. Although the scent is not as intense, that is always the price to pay with products made with natural ingredients :)

    I had never used solid shampoo bar before, so I’m satisfied of results, for 2 main reasons: 1. After washing hair is soft like never before, so you can perceive the power of natural ingredients 2. Usually it gets hard with liquid shampoo to get deeply to the scalp, having long hair, so I end up using much more product than needed. So the other positive fact is that rubbing the bar really works out for deep cleanse The only thing is parfume isn’t intense like usual, but that means you are dealing with natural ingredients.



    Hi Eleanora! We're so happy to hear you comments on our Shampoo Bar. Sometimes, there is a price to pay with products made fully with natural ingredients. However, we're always working hard to improve our products ☺️

    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 oily hair?

    When caring for an oily or greasy scalp you’re trying to contain excess sebum production. Avoid shampoo bars for curly hair and look for those focused on strengthening your hair. But don’t go overboard: clarifying shampoos can leave you with dry skin, which will produce more sebum.

    When having a shower, take your time working the shampoo into your scalp to break up the oil. After applying the conditioner, it’s important that you rinse your hair well.

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

    This Oily Hair Shampoo Bar extracts impurities from your scalp whilst cleaning the pores on your skin. The Charcoal present in the formula will gently exfoliate the scalp, removing excess sebum while the Olive Oil will deeply softener your hair. To be honest, these two are the perfect duo :)

    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.
