Quick answer: salon shampoos can be worth it if you want a product matched to a specific hair need, such as colour protection, frizz or a sensitive scalp, from a range hairdressers use every day. They usually cost more upfront, so the value comes from choosing a formula designed for your hair rather than a general one. The right product for your hair matters more than where you buy it.
What's the difference between professional and supermarket shampoo?
There's no legal definition of "professional" or "salon" haircare, so it's fair to be sceptical. In practice, professional brands are usually made for hairdressers first, sold through salons and approved stockists, and built into targeted ranges: a shampoo, conditioner, mask and finishing product designed to work together on one hair concern. Insight, for example, is made in Italy and has ranges for frizzy, dry, damaged, coloured, curly and blonde hair, as well as different scalp needs.
Why choose a salon shampoo?
Targeted to your hair
Instead of one formula for "normal" hair, professional ranges are designed for a specific need. If your hair is coloured, a colour-protecting routine like Protective is formulated around colour fade. If it's frizzy, Hydrating is formulated around moisture and humidity.
Recognised by the industry
Insight products have won hair industry awards, including Best Serum for Liquid Crystals and Best Shampoo & Conditioner for Colour Care for Protective. See all our hair award winners.
Ingredients and standards you can check
Every Insight product is vegan and cruelty-free, and full ingredient lists (INCI) are on each product page. Some ranges are COSMOS certified, and you can browse our sulphate-free shampoos if that matters to you.
Advice from your stylist
Buying professional haircare means you can ask a hairdresser what's right for your hair, and many salons stock the same ranges they use on clients. Ask your hairdresser, or contact us for advice on the right routine.
Is expensive shampoo always better?
No. Price alone doesn't tell you whether a shampoo suits your hair. A well-matched product used correctly will usually do more than an expensive one chosen at random. Look at what the range is designed for, read the ingredient list, and ask your stylist.
How to get the most from professional shampoo
- Use a small amount and focus it on the scalp. The lather rinses through the lengths.
- Wet hair thoroughly before applying, so it spreads further.
- If your hair is long or thick, two small washes clean better than one large one.
- Follow with the matching conditioner, applied to the mid-lengths and ends.
