These come in a size we cannot express per litre, or carry a pack size we do not trust, so they are ranked by ticket price instead of being mixed into the value list.

Common questions
Which supermarket is cheapest for hair serum?
Lidl, at €39.90/l for Repair Hair Serum with Argan Oil. That is the cheapest hair serum per litre of everything the five supermarkets list today; the last price check ran 23 hr ago.
Why compare per litre?
Because a big pack and a small one are not the same purchase. Dividing each price by its pack size puts every option on one scale, so the cheapest ticket and the best value stop being the same question. Only offers priced per litre are ranked together; the rest are listed separately rather than mixed in.
Most of these are own-brand. How is that a comparison?
Most supermarket items are own-brand, so the honest comparison is the shelf: every option in a category, ranked by what it costs per unit, each row naming its shop. Branded items sold in more than one supermarket still get a single page comparing them directly.
