Can I stop finasteride for a week?

Unfortunately I (21m) am gonna be unable to take finasteride for up to a week because the delivery has had issues. My hair loss is pretty aggressive (as hair loss tends to be for younger people who have it). Is the lack of fin for 5-7 days likely to affect my hair loss?

Enough finasteride is attached to the receptors to last 1-2 weeks safely, so stopping finasteride for a week is usually not a problem.
