I was looking at the ingredients in the Zirh pre-shave. It looked good till I saw the Isobutylparaben, Butylparaben, Isopropylparaben
Many of these Parabens are banned under the EU, I have included a link below which will show this and there is a small snippet next.
(Earlier this year, the Commission banned the use of five other parabens in cosmetic products - Isopropylparaben, Isobutylparaben, Phenylparaben, Benzylparaben and Pentylparaben (See
Commission Regulation (EU) No 358/2014) due to the lack of data necessary for reassessment. Products placed on the market after 30 October 2014 will have to be free from these substances.)

Given that the UK is leaving the EU, you have no worries.
