Professional hair care comes in 250, 300 and 1,000 ml. This guide says how to compare the total across packs and when a litre pays off.

How to count
Total divided by volume, always with shipping: a litre of shampoo at 690 CZK plus 99 CZK shipping is 79 CZK per 100 ml, 300 ml at 290 CZK shipped free is 97 CZK per 100 ml.
In Hair care every offer shows its volume; offers without one are never ranked cheapest.
When a litre
A litre pays off for a shampoo used daily; a conditioner or a mask runs out of a small pack before it ages.
Compare sets (shampoo plus conditioner) against the sum of both items, not against one.
Advice
An unrated shop is never recommended first. With cosmetics check the shop's country too: a Slovak shop ships to Czechia for different money.
Dryers and straighteners live in Hair dryers and stylers; cosmetics and devices are never mixed.
