There are various ways to gain followers, and InsteLikes offers a way to get followers for free. To do this, you need to have coins, which can be obtained for free by fulfilling other users' requests.
First, make sure you're using the correct profile; you can change the profile by clicking on your profile picture in the bottom menu. To gain followers, access the “Promote” page in the bottom menu, and then select "Followers".
You will be able to set the minimum reputation and other options, such as the amount of coins you wish to use and how much you want to offer for each interaction. Note that what you offer determines how quickly (or slowly) you will receive the interactions; you can read more in another article.
Once the request is made, you can track the progress in "History", and wait for other users to fulfill the request.
Growing on Instagram requires consistency. Besides using InsteLikes, post regularly, use relevant hashtags, and reply to comments. The more active and interesting your profile is, the greater the chances of retaining new followers.
If you want even safer results, prioritize real followers. They come from active community users, which reduces risks and increases your profile's credibility.
