In the world of solid shampoos, Lush's Jumping Juniper has developed a devoted following. Marketed as the ultimate solution for oily scalps, this little purple bar promises deep cleansing without the plastic waste. But does it deliver? As a hairstylist with two decades of experience, I've put it through rigorous testing to separate fact from hype.
What makes this review different? Most bloggers focus on surface-level impressions. I'm digging into the science behind the ingredients, long-term scalp impact, and whether its sustainability claims hold up. Plus, I'll reveal how it compares to another top performer - Viori's Citrus Yao bar.
The Ingredients Breakdown: What's Really in That Purple Bar?
Let's start with what makes Jumping Juniper work (and what might make it problematic for some):
- Sodium Lauryl Sulfate (SLS) - The heavy hitter that creates that satisfying lather
- Juniperberry Oil - Nature's astringent for oil control
- Lavender & Rosemary - Soothing botanicals with antimicrobial benefits
- Limonene & Linalool - Natural fragrance compounds that can irritate sensitive skin
The pH Problem You Need to Know About
Here's what most reviews miss: Jumping Juniper has a pH of about 8.5, while your scalp thrives at 4.5-5.5. This alkaline formula can disrupt your scalp's delicate microbiome with frequent use, potentially causing more oil production long-term.
Real-World Performance: Who Actually Benefits?
After testing this on clients with different hair types, here's what I found:
- For oily scalps: Provides excellent immediate oil control
- For normal/dry hair: Can cause tightness and flaking
- For color-treated hair: May strip semi-permanent dyes
The herbal fragrance is potent - refreshing for some, overwhelming for others. And while Lush claims 80 washes per bar, that depends entirely on your hair length and washing technique.
Sustainability: The Full Picture
Lush deserves credit for their plastic-free approach, but there's more to the story:
- Pros: Paper packaging, minimal water usage in production
- Cons: SLS isn't the most eco-friendly surfactant, and essential oil sourcing isn't fully transparent
Compared to Viori's B-Corp certified, ethically sourced bars, Jumping Juniper falls slightly short in the sustainability department.
The Final Verdict: Who Should Buy It?
This bar shines as an occasional clarifying treatment for very oily scalps. But for daily use or sensitive skin, gentler options like Viori's pH-balanced formula work better long-term.
Rating: 7.5/10 - Powerful but imperfect. The right choice depends entirely on your hair's specific needs.
