HOW DO I GET STARTED WITH PERPETUAL?

Each Perpetual Kit includes everything you need: one refillable canister, designed to keep for life, and one initial refill. When it’s empty, simply replace with a new refill to continue your ritual, without the waste.

WHAT IS THE PERPETUAL CANISTER MADE FROM?

Perpetual canisters are made from 100% recycled waste plastic (Post-Consumer Recycled [PCR] Polypropylene). Each canister is designed to be kept and refilled for life, helping eliminate the single-use packaging so common in the beauty industry.

CAN MY CANISTER BE REUSED AND REFILLED?

Yes! Perpetual canisters are designed to be cherished for a lifetime of soothing showers. When you’ve finished your first formula, simply refill and continue the ritual. Our refill packaging is made from discarded sugarcane leaves, once destined for incineration, now given new purpose. After you’ve topped up your canister, the refill pack* can be placed straight into your home compost, completing the cycle. Note: the small sachet that houses the cleanser biospheres is not yet compostable and will need to be disposed of with your household waste.

HOW IS PERPETUAL DIFFERENT?

Many existing eco-friendly options compromise on performance. Perpetual was created to deliver both sustainability and results. Our waterless biospheres and solid concentrates are calibrated for pure performance. Pre, pro + postbiotics, combined with biomimetic peptides and hair re-bonding technologies deliver advanced colour protection and hair repair.

HOW MANY WASHES DOES IT LAST?

Perpetual Hair Cleanser and Conditioner are designed to last around 30-40 washes. How long that is for you will depend on your haircare routine, but we generally recommend washing less often (2–3 times per week) and washing more thoroughly for the best results.

HOW DOES SUBSCRIPTION WORK?

If you subscribe to Perpetual, your first order will include a canister, and then all future deliveries will switch automatically to refills, so that your rituals continue seamlessly without interruption.

IS THE CANISTER RECYCLABLE?

If a canister is ever no longer needed, it has two end-of-life options: + Recycle locally: As a Number 5 plastic, your canister can go into most curbside recycling programs. + Return to Sans: Your canister can be re-ground and incorporated into the next production batch of canisters, so it lives on for someone else to enjoy.

For best results, store your Perpetual Conditioner Bar somewhere cool and out of the sun.

my curly hair loves this
I am so glad to have found this. My thick, course, dry curly hair has been so unhappy with everything else I’ve tried and I thought it was just my hair. Since starting this, along with the hydrant and a couple of infusions, I’ve instantly got curlier, less frizzy, healthy looking and soft hair. It’s incredible how quickly it’s made a difference! Love and highly highly recommend

New concept shampoo/conditioner
I waited for this product to come back into stock and like all the other Sans products I use I love it. I struggle with shampoos that weigh down my thin hair. With this product my hair feels healthier, cleaner and full of volume. I also noticed I don’t need to wash my hair as often. Also the shampoo lathers well from its powdered form.

Great duo that’s easy to use
I’ve been using this duo for a few weeks now and loving it. Easy to use and great for travelling. I have been looking for shampoo and conditioner without nasty chemicals and silicones that also is great for smoothing white/grey frizzy hair. So far so good!
