Pure, simple, and naturally strengthening, our Bamboo Shea Shampoo Bar is crafted to support healthy, vibrant hair with every wash.
Bamboo extract is naturally rich in silica, a trace mineral reported for its role in maintaining strong, healthy-looking hair. It is reported to help gently cleanse the scalp, removing buildup and impurities while supporting a refreshed, balanced feel. Bamboo has anit-irritant and anti-oxidant properties, making it a wonderful choice to naturally soothe sensitive scalps.
Shea butter adds deep nourishment, delivering vitamins A, E, and F and is reported to help hydrate and soften hair while restoring natural shine and manageability. Together, these ingredients create a rich, conditioning lather that leaves hair feeling clean, smooth, and lightly moisturized.
Scented with an invigorating blend of lavender and rosemary essential oils, Bamboo Shea offers a fresh, spa-like experience that feels both grounding and uplifting. Like all Siena Soap bars, this shampoo bar is biodegradable, eco-friendly, lake-safe, and TSA-approved—making it the perfect companion for home, travel, camping, and everyday adventures.
Inspired by the historic Legend of the Four Thieves, Defender combines a powerful blend of clove, cinnamon, eucalyptus, rosemary, lemon, and frankincense essential oils—botanicals that have been traditionally valued for their cleansing, antibacterial, antiviral, and antifungal properties.
Many of these essential oils are naturally rich in compounds such as phenols, carvacrol, thymol, and terpenes, which have been widely studied for their antimicrobial activity. It has been reported that many viruses, fungi, and bacteria struggle to thrive in the presence of essential oils containing these naturally occurring compounds. A nearly identical essential oil blend was tested at Weber State University in 1997 for its antimicrobial properties and demonstrated a 96% effectiveness rate against certain airborne bacteria under laboratory conditions.
Our Defender Facial & Shampoo Bar pairs this robust essential oil blend with nutrient-rich neem oil and moisturizing plant oils to create a deeply cleansing yet nourishing bar for the face, hair, and body. Customers have reported excellent results using Defender on eczema- and psoriasis-prone scalps, as well as acne-prone skin, appreciating its ability to leave skin and scalp feeling clean, balanced, and refreshed.
Known for its rich lather and clarifying cleanse, Defender is especially well suited for oily, blemish-prone, or scalp-stressed skin. Whether used as a facial cleanser, shampoo bar, or full-body soap, it offers a simple, effective routine without compromise. Like all Siena Soap bars, Defender is biodegradable, eco-friendly, lake-safe, and TSA-approved—making it the perfect companion for home, travel, camping, and everyday adventures.

Soap on a rope the environmentally friendly way!
We love these soap bags! So much, in fact, that we decided to start selling them on our site so you can enjoy them too!
You can scrub up with Siena Soap naturally by tucking it into an open weave soap bag with a drawstring closure. One side is an open mesh and works nicely as a light exfoliant. The reverse side is a denser weave, soft like a washcloth.
It is the perfect size for your favorite Siena Soap Bar. Or collect all those end pieces of your favorite soaps and enjoy them until their very end.
The bags are approximately 4″W x 4.25″H. The bags are made with 100% natural cotton by Eco-Bags – another American Woman-Owned Business!
