To clear your search history on Instagram, you can follow these steps:

1. Launch the Instagram app on your mobile device. Please note that these instructions are for the Instagram mobile app and may vary slightly depending on your device’s operating system.
2. Go to your profile by tapping on the profile icon located at the bottom right corner of the screen.
3. Once you’re on your profile, tap on the three horizontal lines icon (also known as the hamburger icon) located at the top right corner of the screen. This will open the menu.
4. Scroll down the menu and tap on the “Settings” option at the bottom.
5. In the Settings menu, scroll down and tap on the “Security” option.
6. Under the Security menu, you’ll find the “Clear Search History” option. Tap on it.
7. A confirmation pop-up will appear asking if you want to clear your search history. Tap on “Clear All” to proceed.
8. Instagram will now clear your search history, including all the previous searches you’ve made.

Please note that clearing your search history on Instagram will remove all the previous searches from your account, and you won’t be able to retrieve them. This action only clears the search history on your device and does not affect the search results or suggestions for other users.
