Ideally you want to find a balance between all your goals, but sometimes they can conflict. For example, wanting long and healthy hair but wanting to dye it lighter too. Another example is sea salt spray which gets those curls to bounce, but its super drying and will lead to your hair breaking over time. Therefore, it is important to assess what hair goals are at the top of your list. For example, if your goals are to grow your hair longer and prevent breakage then choose the advice that is going to help you achieve these things first. It is important to note that fine hair is more prone to external stressors as it doesn't have as many cuticle layers to protect it. So if the goals mentioned above are important to you, this means you should focus your efforts on practices that are compatible with fine hair and help to strengthen it. If your curls are more important to you, then you could focus more on practices for curls. Experimentation is key, and you just have to decide what is best for you unique situation and then adapt your routine as you figure out what works best for you.
