Essentials for getting ready to go out

This is a very famous product, isn't it? It is Gatsby Set & Keep Spray Super Hard Hair Spray.

My hair is thin and lacks volume, so it loses its shape quickly even after using a curling iron, making hairspray a must for me. I've tried various products, but since seeing so many recommendations for this one, I decided to buy and give it a try. I've settled on this product and have been using it consistently ever since. It holds its style well, the price is reasonable, and while it has a scent, it isn't overpowering or unpleasant, which I really like. What kind of hairspray do you guys use? Please share any tips for fixing your hair besides spray! I'm really worried about how to maintain my weak hair, especially since it's the rainy season.
