What to get for someone who wants to start tending to their wavy/curly hair more?

I am getting married soon, and one of my bridesmaids has medium length, curly hair. They just use shampoo and conditioner right now (I don’t know what brand, but I know they wish it was better), and I think they always let their hair air dry. I don’t know how often they wash it, but they work in a dusty, hot place, so I bet they’d want to shower every day or two after work. I know they feel a bit daunted by the sheer number of products/tools, etc that are available, and right this second they don’t have a ton of time to diffuse their hair.

I want to gift them something to get them started: I thought about a turban for after they shower, a satin pillowcase, or maybe a prose gift card (is prose legit?). Any product suggestions etc will do. If it helps, based on charts I see online, I’d guess they’re at about a 2C or 3A right now.
