How do I delete my Instagram search history?

Instagram saves searches in Search & Explore to make it easier for you to quickly find your favorite tags and favorites. To clear search history:

Tap to open your profile
Tap (iPhone) or (Android) at the top right
Scroll down and tap Clear Search History
Keep in mind that clearing search history is temporary, and searches you clean may reappear in your history after you search again.

You can also hide individual accounts, tags or places to permanently delete them from your search history and not to reappear:

Tap then tap the search bar at the top of the screen
Under Top or New, tap and hold the search you want to hide from your history
Tap Hide
