Hair Growth

So I'm getting married in October. Starting to try lifestyle changes to be in the best shape possible so I look flawless by then. One thing I'm noticing is my hair health not improving. I'm trying to drink a lot more water, take vitamins, and wear it natural to eliminate as much heat as possible. I want long curls in a half up half down style, but my hair is only right below shoulder length atm. I've been trying to get regular trims as well, but as soon as it grows back to this point it starts breaking again. My natural hair is pretty curly and dry. I looked at a chart to explain and I have 3B pattern, but more dryness. Any tips on good hair growth products/home remedies you used to get ready for the big day?
