Theorie Haircare NZ | Official Stockist | Zilion
Theorie in New Zealand
Theorie is a salon haircare brand built around botanical oils and extracts. Each range is named for the ingredient at its centre: Argan Oil, Marula Oil, Purple Sage, Helichrysum, Amber Rose and Tea Tree & Ginger. The result is a short, easy-to-follow line-up of shampoos, conditioners, serums and a mask that covers repair, smoothing, blonde toning, hydration and scalp care.
Zilion is an official NZ stockist of Theorie. We carry the shampoos and conditioners in 400ml and big 800ml bottles, 90ml travel sets, the serums and the Sage Restore Mask, along with duos, trios and 4-piece travel kits. Anyone looking for a Theorie stockist in New Zealand will find the full range here, priced in NZ dollars.
About Theorie
Theorie keeps things simple. Rather than dozens of overlapping products, each range has a clear job and a signature ingredient, with a shampoo and conditioner at its core and a serum or mask where the hair needs extra help. The formulas are professional grade and finish with a noticeable fragrance, which is a big part of why people stick with the brand once they find their range.
The 800ml bottles are one of the main draws. For households that wash often, or anyone who has settled on a favourite, they bring the cost per wash down considerably, and the 400ml sizes and 90ml shampoo and conditioner sets make it easy to try a range first.
The Theorie Range
Argan Oil. Theorie's repair range, built on Moroccan argan oil for hair that is dry, dull or worn down by heat and colour. It covers Argan Oil Shampoo and Argan Oil Conditioner in 400ml and 800ml and the lightweight Argan Oil Restoring Serum 60ml, and it is our best-selling Theorie range.
Marula Oil. A sulphate-free smoothing range that pairs marula oil with argan oil for frizz-prone, coloured or heat-styled hair. Choose Marula Oil Sulphate Free Shampoo and Conditioner in 400ml or 800ml, finish with Marula Smoothing Serum 60ml, or try Marula & Argan Sulphate Free Shampoo and its matching conditioner.
Purple Sage. Brightening care for blonde, silver and highlighted hair. Purple Sage Blonde Shampoo uses violet pigments to neutralise brassy and yellow tones, the conditioner keeps lightened hair soft, and Sage Restore Mask 200ml is an intensive treatment with sage leaf extract and proteins.
Helichrysum. A nourishing range for dry, brittle or over-processed hair, made with helichrysum extract. Helichrysum Shampoo and Helichrysum Conditioner come in 400ml and 800ml, and the Helichrysum Nourishing Gift Set adds the Argan Oil Restoring Serum.
Amber Rose. The hydrating range, loved for its scent. Amber Rose Shampoo 400ml and Amber Rose Conditioner 400ml add moisture to thirsty hair and help protect colour.
Tea Tree & Ginger. An invigorating scalp-care pair. Tea Tree & Ginger Shampoo 400ml lifts away oil and product residue with a cooling, fresh feel, and the matching conditioner keeps lengths soft.
Shop by type. Browse Theorie Shampoo, Theorie Conditioner, Theorie Hair Serums and Theorie Hair Masks, or go straight to Theorie Gift Sets & Packs for duos, trios and 90ml sets. The 4-piece hair and body travel kits sit in Theorie Body Care.
