Short answer: shaving does not make hair thicker, more blades do not always mean a closer shave, pressing harder does not help, cold water does not close pores and stinging aftershave does not mean it is working. A fresh blade, warm water, plenty of lather and light pressure are what really matter.

Shaving advice gets passed around without much checking. Here are seven myths and what is actually true.

The seven myths

MythThe truth
Shaving makes hair grow back thickerIt does not change thickness, colour or speed. Regrowth can feel coarser because the cut end is blunt.
More blades always give a closer shaveNot necessarily. Technique, prep and a fresh blade matter more. See 3-blade vs 5-blade.
Pressing harder gives a closer shaveIt mostly causes nicks and razor burn. Let the blade glide.
Cold water closes your poresPores do not open and close. Warm water softens hair, which is what helps.
If aftershave stings, it is workingStinging is irritation, often from alcohol. An alcohol-free balm is gentler.
You must shave against the grainNot required. With the grain is gentler and lowers the risk of bumps.
A pricey razor is always betterA fresh blade and good technique count for more than the price tag.
