Highland, the haircare brand specializing in high-performing, non-toxic products, is taking rosemary from kitchen cupboard to haircare heavyweight, with a new conditioner alternative, The Condish, a next-generation, broad-use conditioner powered by botanicals and clinically-tested ingredients that hydrate and strengthen hair while supporting scalp health.
More than two years in the making, The Condish was developed in response to traditional conditioners which coat hair in synthetics and silicones, which Highland said creates the illusion of moisture while blocking the real thing.
“They congest your scalp, accelerate buildup, leave hair looking dull and weighed down,” said Highland Co-founder Ben Medalie.
“With our Glacial Clay Pomade and Glacial Cream, we’ve already transformed the way people approach styling products. Completing the ritual meant taking the same standard into the shower. The award-winning Wash reimagined the cleanse. The Condish is our answer to everything after.”
Formulated in partnership with hair professionals, leading organic chemists, and cosmetic experts, The Condish replaces these synthetics with botanical and science-backed ingredients that power a high-performance, weightless conditioner that genuinely hydrates.
“We’re a brand that doesn’t take ourselves too seriously, but we take ingredient integrity and innovation more seriously than anyone else in the industry. This truly is a conditioner evolved,” said Boone Whiteside, co-founder of Highland.
“We set out to thread the needle on making a product that felt premium in the shower, supplied true, long-lasting conditioning, and was made with innovative, clean ingredients. Developing The Condish was strenuous, challenging and illuminated why most conditioner formulas are built the way they are—and exactly why this launch was necessary.”
At the heart of The Condish are clinically-proven ingredients selected for both immediate performance and long-term benefits, including caffeine, Amazonian Babassu Oil, Hydrolyzed Jojoba Protein, Cupuaçu Seed Butter, and Aquaxyl™, an advanced humectant complex that supports moisture retention and hydration.
Rather than treating conditioner as something that simply softens the lengths, The Condish combines rosemary with biotin, and panthenol to support the scalp while delivering lightweight hydration, detangling and strengthening benefits.
Highland said that while other conditioners lean on a few highly marketable active ingredients and leverage fillers for the balance of the formula, with The Condish, every single ingredient was scrutinized and had to earn its place—satisfying specific performance metrics (slip, detangling, hydration, anti-static, etc.) and hair health impact.
Infused with functional aroma notes of Siberian Fir and Rosemary, The Condish is free of silicones, artificial fragrances, sulfates, parabens, SLS, and gluten. It is designed for professional and at-home use, is color-safe, and suitable for all hair types.

The result is a conditioner designed to care for both the hair you can see and the scalp underneath it without relying on silicones, sulfates, or synthetic fragrances.
From Aveda’s Rosemary Mint Purifying Shampoo to Mielle’s viral Rosemary Mint collection and Nécessaire’s Rosemary Shampoo, the botanical has become one of the most recognizable ingredients in scalp and hair care, but its appeal goes beyond its fresh, herbal scent.
Research has explored rosemary’s role in supporting healthy hair growth. One clinical trial found that rosemary oil and 2% minoxidil produced comparable improvements in hair count after six months among people with alopecia. Research has also pointed to rosemary’s antioxidant properties, all which can contribute to a healthier scalp environment.
Studies have also explored its potential to support hair growth and circulation, with compounds such as 1,8-cineole, camphor, and rosmarinic acid contributing to its biological activity.
The Condish retails for $36 and can be purchased on Highland.style and Amazon.
