I just use Thayer, then an aftershave for scent.
That's funny, I have the same exact Thayer's witch hazel in my house. I keep the Cucumber in the fridge and feels great on really hot days.I use both after shaving. I first use the alum on my wet face. Then after a few minutes I splash fresh water on my face. I dry that off and splash on the Thayers. I use the cucumber, super medicated or peach depending on my mood.
I use both every shave I like the Thayers Superhazel, first the alum then Thayers.
