Synergy Hair on Willis Street is a hair salon at 28 Willis Street in the Wellington CBD, and part of the Synergy Hair chain. Its website says the salon stocks 86 professional brands across hair care, colour and tools, so the shelves are as much a draw as the chair.
The current offer on the website is the Hot Muk straightener, a hair straightener used in the chain's salons, for $199 with a free Hot Muk, valued at $315 (as at 2026). Products on the site include the K18 Leave-In Molecular Repair Mask at $149.00 and the Olaplex No.5 Bond Maintenance Conditioner at $49.95, both as at 2026. Synergy Hair e-gift cards are also sold, so a visit can be given as a gift.
