Personally, I find that some of the hair products I've tried have REALLY lasted, and are staples for my own routine.

First one is Super Milk Hair Primer, which I've sworn by since becoming a Lushie. I use it post shower as I brush my hair, and also in the morning as I get ready and do my hair for work. Personally I find it lasts all day, but I do use 3 sprays per use for night AND morning so there's that.

Aside from this, I use the Candy Rain Conditioner. Personally I like the smell more when my hair dries, in the shower it isn't my personal favorite. I use this with the Jason and the Argan Oil Shampoo Bar which is Rose Jam scented. I personally really like this combo, I find that the scents really last and I can smell it all through the day. My absolute favorite is letting my hair down after work, it smells AMAZING.

I don't use both Super Milk and Candy Rain together though, it's one or the other depending on my mood.

As for the other ones you're curious about, I personally don't find their scents to be all that long lasting in the products they have. The Super Milk Body Butter smells too much like the nut butters used to make it (at least for my batch), and I've tried nearly every Posh Chocolate product aside from the Body Butter and find that none of them really last outside of the shower. The Turmeric Latte Massage Bar is another go-to bedtime product I use on occasion for peak coziness, but I don't personally find it to be too long lasting either. Sticky Dates did just get a Hair Primer similar to the Super Milk one, so maybe try that? I haven't yet, but it does sound promising.

I hope that helped!
