Made with a nourishing blend of ingredients like shea butter, betaine, and cocoa butter with a fresh lemongrass scent. Professor Curl will help promote soft hair and defined curls. You won’t find any sulfates, silicones, waxes, or drying alcohols in this dreamy little bar. Instead, you’ve got a solid shampoo that is equivalent to three bottles of salon-quality goodness that gently lathers for fresh, bouncy curls. Safe for color-treated hair, too!

    Not for me

    I bought a whole lot of minis quite some time ago during a special and finally got around to trying this one. Although despite the smell being amazing (reminds me of an exotic holiday) and my hair being curly, I found this shampoo weighed my hair down too much. I also found my hair was needing washing more often. Unfortunately this one didn’t work for my fine hair.

    Hi Andrea,

    Thanks so much for taking the time to leave feedback on our Curl Defining Shampoo Bar Mini, although I'm sorry to hear that this product wasn't the right fit for you!

    Based on what you've shared, it sounds like you're in need of a shampoo that offers a deeper cleanse compared to the product you tried. You mentioned you bought a few minis, did you try any other shampoos? if so, how did you find them?

    We have a product guarantee and would love to help you find a shampoo bar better suited to you. If you're interested in this, please flick us an email at hello@ethique.com and include what your roots are like e.g. oily, dry, sensitive, balanced etc, and delivery details - from here we can send you out another mini to try!

    ~ Georgia

    Nice product

    I use it probably once a week before using the curly cow ash conditioning bar, which I use more often.

    Lovely products.

    works well

    I think it has made a difference to the quality of my curl. It's quite gentle which is great, but sometimes have oily roots though so I mix it up with the st clements shampoo bar for a more thorough cleanse every few washes.

    Love it 99% of the time!

    Clarifies and washes hair nicely, pairs so well with the curly hair conditioner. Sometimes it can feel a bit too stripping but mostly a great result
