You do not need a large following to grow on Instagram. You need content that helps a specific person, posted consistently, in a format the platform can show to new viewers.
Start with short, useful Reels and carousels that solve one small problem. Use a clear hook in the first few seconds, keep the message simple, and end with a reason to follow or save the post.
Next, study what works. Look at your saves, shares, and watch time, not just likes. When a topic performs well, create more versions of it with a new angle, example, or story.
Finally, be patient and steady. Growth without followers is often slow at first, then builds as the platform learns who enjoys your content. Focus on value, and the audience will follow.
