Product details

This award-winning formula delivers noticeable volume and effective cleansing without stripping natural oils. A specialized blend of green tea antioxidants, shea butter, and lemongrass work to remove product build-up and regulate oil production, extending time between washes. Rahua oil fortifies strands from within to help prevent breakage, while lavender and eucalyptus create a calming, uplifting aromatherapy experience.

The result is lifted, bouncy hair with a healthy, protected scalp. Ideal for daily or occasional use, this formula creates a balanced lather that cleanses thoroughly without causing dryness, making it perfect for those with fine to medium hair seeking natural fullness.

Best For: Fine to medium hair types, including oily scalps and color-treated hair.
Natural Notes: Eucalyptus and Lavender

    Dreamy shower expereience.

    I love the way my hair feels and smells after washing with this—it’s truly a spa-like experience every time. What makes it even better is knowing it’s made with all-natural ingredients, which are gentler on my body and don’t disrupt my endocrine system. Plus, it’s an eco-friendly choice: cleaner ingredients mean safer graywater for reuse and less impact on the environment overall. It’s a small switch that feels luxurious and responsible at the same time.

    I bought the classic shampoo. It smells so good. And makes my hair shinny. I love it. Will buy the conditioner later.

    Excellent product

    I find this to be an excellent product. Only a small amount is needed and that’s for quite long hair which I have. It makes my hair feel soft and it also gives shine.

    Never change!

    I cannot use anything with sodium benzoate (or benzoic acid derived ingredients) in & this is, legitimately, one of the few things suitable for me. Over the years my choices have shrunk & shrunk as it appears in more & more formulations.

    I cannot afford to use this but I have no choice so I love that it's also an excellent shampoo!
