“Treat” shampoo (2-in-1??) and body wash suggestions?

[Catforaheadrest]

My DF(riend) is an ITU nurse. She mentioned that she’s started showering at work before going home. I want to send her some “treat” level body wash and shampoo.... can you GET 2-in-1 shampoo and conditioner that is “treat” level for luxury and speed? I’m sure she’d like to get showered quick as possible!
The most exotic stuff in my bathroom is treseme. When I’ve ventured onto Instagram for ideas... errr... it’s all got a bit beyond me.
Suggestions? TY!

Or Floris Cefiro conditioning shampoo. Diptyque also does a shampoo and shower gel 2 in 1.
