One kit often does two treatments

Every kit carries 50ml of the Step 1 shampoo and Step 3 mask, enough for two rounds. On shorter hair the Step 2 formula usually stretches to a second treatment too, so one kit can cover months of smooth hair.

Nothing goes to waste

The spout pouches reseal and the formula keeps for 12 months, so leftovers wait for your next touch-up. Still unsure? Send us a photo of your hair and we’ll tell you which kit to order.

Top up a single step

Need one more pouch? Replace just that one.

Add an extra 50ml pouch when one step runs out first, when you have product left from a previous treatment, or when longer and thicker hair needs a little more.

Questions, answered.

Will it work on my hair type?+
It’s made for frizzy, wavy, curly and coloured hair, fine through to very thick. It smooths and relaxes rather than poker-straightening, so you keep movement.
Is it safe to use at home?+
Yes. 0% formaldehyde and a much lower fume level than salon straighteners. Open a window, wear the gloves supplied, and you’re set.
How long does it last?+
Three to four months with sulphate-free aftercare. It fades gradually, with no harsh regrowth line.
What if it doesn’t work for me?+
Every kit is backed by our 45-day money-back guarantee*. If you don’t get the result, email us with your before and after photos and we’ll arrange a refund of your kit price.
