Who it's for
Anyone curious about the viral 'green triangle' hair soap trend who wants a plastic-free, travel-friendly bar alternative to liquid shampoo.
Why we recommend it
We feature it because the exact 'green triangle' shape and color are a real, consistent detail across the actual listings behind this trend (not just an AI-generated thumbnail), and it's priced as a low-risk way to try the trend rather than a costly treatment commitment.
Pros
- Distinctive triangular bar shape and green color, genuinely different from a normal shampoo bottle or bar
- Solid-bar format is compact and spill-free for travel, and lasts longer per ounce than liquid shampoo
- Herbal ingredient blend (Usman grass, cypress leaf) with a strong, noticeable lather
- Plastic-free bar format cuts down on bottle waste compared to liquid shampoo
Cons
- No independent clinical evidence backs the hair-regrowth claims common in social videos about this product — treat it as a shampoo bar, not a medical treatment
- A bar-shampoo texture and lather feel different from liquid shampoo, which can take a wash or two to get used to
- Anyone with a diagnosed hair loss condition should talk to a doctor rather than relying on a soap bar alone

Common questions
Does this shampoo bar actually regrow hair?
There's no independent clinical evidence for the hair-regrowth claims that circulate with this trend. It's a novel, well-reviewed herbal shampoo bar — treat any hair-loss benefit as anecdotal, not medically proven.
How is a shampoo bar different from using liquid shampoo?
It's a solid, concentrated bar you rub directly onto wet hair or lather in your hands first — no bottle, no measuring, and it typically lasts longer per use than liquid shampoo, though the lather feels different at first.
Is it safe for color-treated hair?
Herbal bar shampoos are generally mild, but always patch-test and check the specific listing's ingredient list if you have color-treated or chemically processed hair.
