I dont have a mixer is there another that I can make a moisturizer?

I just put some shea butter in a bottle added some hot water so it'll melt and I am shaking it as I do this. Hopefully, it'll ended up being some moisturizing water. Then once the water cools, I will spritz it on my hair. IDK how this will work.

So if you have any other tips, just let me know.
