The post shave routine is really a YMMV thing, you will have to experiment and find what is best for you. For me part of the fun is trying all the different aftershaves and balms etc.

MY post shave routine is as follows:

1) Alum Block
2) Cold Water Rinse
3) Pat Dry
4) Thayers Witch Hazel with aloe
5) Clubman Vanilla AS
6) ASB (Either AOS Lavender, or TH Grafton for now, waiting on more samples )


Many places offer sample packs of creams/balms you can try (Truefitt and hill for example)

Some are very expensive and some are a lot more reasonably priced

Hope this helps
