Welcome! ^^ always nice to see a fellow Dutchie here
Do you want to buy products online? If you want to buy products in store I have a few tips for you: Neutral conditioner (several supermarkets like Jumbo), l'Oreal Elvive hydra curl hair mask, l'Oreal Elvive Volume collageen, Inecto Coconut conditioner, Kruidvat cremevoeding (leave-in), olive line / aloe vera line (Action), Yes to Carrots/Tomatoes/Cucumbers (De Tuinen)
All these products are sulfate/cone free ^^
Btw, since you have coarse hair, your hair might not like proteins.
Hope you have fun here ^^
