Isolated hashtags on IG were often not useful for finding specific content. To find what you want you'd need an interface to a page that showed posts across multiple hashtags which they didn't provide.
For example, posts that contain both #jenniferlawrence and #hoodedeyes would be what you are looking for, and if you interacted with enough posts containing both of those tags you would end up seeing the content you want, you just can't do it directly by navigating to those hashtag pages individually.
I used to provide this in my free hashtag suggestion app (which I kept online because it was, IMO, the best at what it did and still gets 500k hits a month). The app allows users to iteratively navigate the hashtag graph to a final set of tightly related tags. Anyway, during this refinement process users would see a grid of post thumbnails where the posts contain the desired hashtags. Facebook eventually tightened access to IGs API and blocked my ability to provide this thumbnail grid, but the rest of the app is still standing
