I want to buy this for slick backs. Will it last the whole day or should I use hair spray, and if so, what hairspray should I use?

I use this for slick backs. I usually have to redo it about 2-3 times a day unless it’s a hair wash day. If you want to use hairspray, I like the Dae one, but I never hairspray when I use this product or my hair will feel too heavy. It’s more of a preference thing IMO.
