A decent razor is a must and you'll love it for a while. Then you'lll need to buy some blades and it's like, wtf, £14 for 4 omg!!!*
Save money on the gel, Sainsburys own gel is just as good as Gillette's expensive stuff.
*blades may not actually cost that much, but they are damn expensive.
Gel?
Shaving oil ftw imo
