On a single set you can stimulate the same level of hypertrophy for any rep range provided you are training to failure.

However, over the course of an entire workout or week of workouts, exercising in high rep ranges may cause excessive systematic fatigue and make it much harder to reach actual muscular failure.

Since the main driver for hypertrophy is taking the targeted muscle close to muscular failure as possible, it is ideal to reduce the number of factors limiting your ability to do that.

This makes the ideal range somewhere between 6 and 12 reps for each set, but this should not be used as a definitive target, just a recommendation. Doing sets in a high rep range is if course fine, but may be difficult to perform optimally over longer periods if your goal is muscle growth.
