In PnP, it's generally assumed a caster always has the material components and focuses needed for spells in their spell component bag. So even if a spell is listed to require a lock of hair or whatever, it's usually ignored. The only time this doesn't apply is when a component is either very expensive or wouldn't realistically fit into a spell component bag.
If you want to know if a spell has a material component and what it is, then look
here. If the spell isn't listed with M or F in its components, then it doesn't have one.
