Hi Tink64, yes you can use Thayers Witch Hazel. What I would do is dissolve the SA first prior to adding it to the Witch Hazel. You can get it to dissolve using a little Everclear. Once dissolved, then add it to the Witch Hazel.I don't have Witch Hazel Extract but I do have Thayers Which Hazel and aloe toner. Can I add 2% of SA to the Thayers toner or do I have to use the extract? The Thayer toner is alcohol free.
