How does a sulphate-free shampoo like this one differ from regular shampoos, and what should I expect when I switch?

Regular shampoos typically use sulphates (SLS/SLES) to create abundant foam and strip away oil aggressively. This Planeta Zdorovia shampoo omits sulphates and sodium chloride, so the lather is lighter and the scalp doesn't feel "squeaky" or tight after rinsing. That milder base is why it's often chosen for coloured hair, sensitive scalps, and daily washing — it removes dirt and excess sebum without disturbing the hair's lipid layer or fading dye as quickly.

When you first switch, your hair may feel different for a few washes: less foam, a sensation that it's not "clean enough," or even a temporary increase in oiliness as the scalp rebalances. This is normal. Use lukewarm water, massage the scalp for 30–60 seconds, and rinse thoroughly. Most people adjust within 2–4 washes. If you use styling products with heavy silicones or waxes, you may need a clarifying wash once every couple of weeks, since gentle surfactants don't remove heavy buildup as effectively.
