Salon vs supermarket shampoo: it comes down to concentration
The biggest difference isn't some secret ingredient. It's concentration. Supermarket shampoos are formulated to be cheap to produce at huge volumes, which means the active, beneficial ingredients are often diluted right down. Salon-quality brands like Kérastase, Pureology and Matrix use a much higher concentration of the ingredients actually doing the work, which is part of why a bottle often lasts longer than you'd expect despite the higher price.
What's actually in the bottle
Supermarket shampoos lean heavily on sulphates and fillers to create lather and bulk, because that's what makes a product feel like it's "working" even when it's mostly stripping your hair. Salon-quality formulas are built around your actual hair concern, whether that's colour protection, hydration or scalp health, using ingredients chosen for a purpose rather than shelf appeal.
Why supermarket shampoo can work against you over time
If you've spent money on a colour service or a keratin treatment, a harsh supermarket shampoo can undo that investment faster than you'd think, stripping colour and drying hair out within a matter of weeks. This is the bit people notice most: colour fading faster, and hair feeling "different" a month after a salon visit. It's usually the shampoo, not the treatment, letting the results down.
So is salon shampoo worth the extra cost?
If you're investing in colour or treatments, or you simply want your hair to look and feel healthier day to day, yes. It doesn't have to be all-or-nothing either. Our budget-friendly Matrix range gives you salon quality without the premium price tag, so there's an entry point at every budget. And because we ship salon hair products NZ-wide, you don't need to live near a salon to make the switch.
Frequently asked questions
Will switching to salon shampoo really make a difference?
Yes. Most clients notice a difference within 2–3 washes of switching to salon shampoo, particularly in how soft their hair feels and how well their colour holds.
Do I need to use the matching conditioner too?
It's not essential, but a shampoo and conditioner from the same range are formulated to work together, so you'll get better results using both.
What's the biggest mistake people make with salon shampoo?
Using too much. Salon shampoos are concentrated, so a small amount goes further than the handful you'd use with a supermarket bottle.
Is salon shampoo worth it if I don't get my hair coloured?
Yes. The same concentration and quality benefits apply whether your hair is coloured or natural. It's about the health of your hair, not just protecting a colour job.
