The good news is that you can have your niche audience follow you on Instagram. The bad news is that if you don't use hashtags you will find great difficulty in building your following. Here are some tips on how to use hashtags within your posts:
Use Hashtags Within Your Comments
While you do have the opportunity to use 2200 characters in your caption, it looks cleaner to separate the hashtags out. Use the Caption area to get your message across.
Choosing Your Hashtags - You can use up to 30 hashtags and they can be industry, niche, branded, community, location, event and celebration day.
