Sante shampoo and conditioner

I bought this natural cosmetics set (250 ml shampoo for strengthening hair and 150 ml mask for shine), but it didn't suit my keratin-treated hair. Both products have only been used twice.
9 euros for the set OR 5 euros each. Descriptions can be found in the attached images, in the Livin store, and elsewhere on Google. Shipping is paid by the buyer.
