How to choose: Hair oils, serums and treatments under €25

Hair oils, serums and treatments include leave-in oils for the ends, scalp serums, tonics and ampoule courses used alongside your regular wash routine. Bottles are small and concentrated, so compare the price per 100 ml or per course, and check whether a set with shampoo from the same line is cheaper.

  • Compare the price per 100 ml, not the price of the pack — a bigger bottle is often, but not always, better value.
  • Check the price incl. delivery: a cheaper product with paid delivery often loses to a pricier one with free delivery.
  • Before a sale, look at the 30-day price history on the product page — it shows whether the discount is real.
  • Not in a hurry? Set a price alert — we e-mail you once when the price drops to your amount.
