Behind HairGym
Celebrity hairdresser Elle saw the same struggle in her chair every week: clients forced to choose between their workout, busy lives and their hair. Touring musician and gym girlie Arianna was living it herself, and she was done compromising. Together they asked one question: why can't your hair train while you do?
You ask, we answer
Help & FAQ
Apply to damp or dry hair before your workout. Distribute evenly from the scalp to the tips, then train as usual. Afterwards, wash your hair as normal or leave it in as a slick back and go about your day. You can leave it in all day. Not training today? Apply it anyway and leave it in for at least 10 minutes.
Think of it like training, consistency builds results! Use it 2-3 times a week for best results, ideally on your training days. More active? You can use it every session.
Your sachet is designed for multiple workouts, not one. Coat hair generously from scalp to ends, enough to look slick, not patchy. Concentrated formula, so less than you think but don't skimp.
4+ uses per sachet, depending on your hair type, length and thickness.
Visible shine and softer hair from the first use. With regular use, expect smoother, more manageable hair that looks and feels healthier over time.
Anyone who wants great hair but doesn't have the time to sit around waiting for it. All hair types. It's built to work with your lifestyle, not against it.
Most hair masks are designed for the bathroom. Ours is designed for real life.
Active lifestyles put constant stress on the scalp and hair: sweat, frequent washing, heat, friction, tight styling and more. Our formula is dermatologically proven to support scalp balance, promoting hair longevity, while strengthening and enhancing visible shine. It is lightweight enough to wear while you train, yet highly concentrated so you only need a small amount. No heaviness. No Added Steps. No wasted time.
Each mask comes in a gym-ready sachet that won’t leak or weigh down your bag, so you can treat your hair wherever your day takes you. We spent a year formulating and testing with real gym-goers to ensure it performs through sweat, movement, and real workouts.
