The next generation of hair repair has arrived.
At Joshua Altback, we are proud to introduce Hair.TOXX Cryotherapy — an advanced, luxury treatment that restores strength, hydration and shine using the power of sub-zero technology.
This is not a traditional smoothing service. It is a deep restorative treatment designed to transform the health of your hair from within, without compromising its natural texture.
Hair.TOXX is the world’s first professional cryotherapy treatment for the hair and scalp, working at temperatures as low as -16°C to deliver active ingredients deep into the hair fibre.
Instead of coating the surface, this treatment infuses and locks nutrients inside the cortex, where real repair happens.
The result is instantly smoother, stronger and more radiant hair after just one session.
Hair.TOXX brings cryotherapy into professional haircare, using sub-zero technology to freeze restorative nutrients deep within the cortex for results you can see immediately.
Expect up to 264 percent more shine and hydration from a single session, along with stronger, smoother hair and a beautifully balanced scalp.
Trusted by salons and trichologists in more than twenty countries, and winner of Hair Product of the Year at the Beautyworld Middle East Awards, Hair.TOXX has quickly become one of the most talked-about innovations in the industry.
Clients love the instant transformation. Professionals value the science behind it and the confidence it brings to every service.
Every Hair.TOXX service begins with a detailed consultation so your stylist can fully understand your hair and scalp.
A bespoke blend of formulas is then selected to target exactly what your hair needs most.
Once applied, the Frozen Machine seals the nutrients into the hair using sub-zero temperatures. You may even notice a delicate layer of ice forming — a sign that the ingredients are being locked deep into the cortex for maximum repair.
Daily styling, colouring and environmental stress gradually weaken the hair structure. The cuticle lifts, moisture escapes and the cortex becomes exposed.
Hair.TOXX reverses this process using cryogenic technology.
When exposed to cold, the cuticle contracts and seals tightly, allowing nutrients to penetrate deeply and remain inside the fibre. This restores strength, elasticity and hydration from within.
Unlike heat-based treatments, this process supports the structure of the hair rather than compromising it — delivering long-lasting results.
Why the Coldest Trend in Beauty Is Taking Over London
For years, cryotherapy has been associated with high-performance wellness and advanced skincare. Now, this same sub-zero technology is transforming professional haircare.
Hair cryotherapy is one of the most exciting innovations in the beauty industry, with more clients choosing treatments that repair rather than mask damage.
The Rise of Cold Beauty
Modern beauty is shifting towards treatments that strengthen rather than stress.
Cold therapy helps reduce moisture loss, improve resilience and enhance the performance of active ingredients — making it the perfect evolution in hair repair.
How Cold Transforms the Hair
When exposed to cold, the cuticle contracts and lies flat. This creates a smoother surface, increasing shine while locking in hydration.
Hair feels softer, looks glossier and becomes easier to manage — without relying on heat styling.
Why Cryotherapy Delivers Better Results
Cold temperatures allow nutrients to penetrate deeper into the cortex, where strength and elasticity are controlled.
Instead of sitting on the surface, ingredients are sealed inside the hair fibre, delivering longer-lasting repair and a more natural finish.
Hair.TOXX formulas combine advanced cryogenic technology with nutrient-rich ingredients sourced from the Amazon.
Açaí Berry – antioxidant protection and shine Glacial Water – soothing and mineral-rich hydration Hyaluronic Acid – elasticity and moisture balance Avocado Butter – nourishment and softness Propolis – scalp protection and calming support
