I change by feel, once I feel that there's too much drag during shaving, that's it... change new head...
I'm a sucker for buying fancy crap, so I've got the latest five-bladed battery powered Gillette something something. It actually does feel a lot smoother and less likely to cut into your skin than the previous models.
But I'm also lazy, so once in a while, I get a good pair of tweezers and pluck out every single chin hair that I have. Lasts at least one week, as opposed to one day.
Especially for you then.....
I'm thinking of going DE myself....been contemplating on a Merkur HD #34C
I think 3 blades is the max i'll go. 3 blades is already like 3 passes with every 1 pass. 5 blades would be hell for your skin. Imagine doing 2 passes with a 5 blades cartridge. 10 passes!!!
Thought of getting Fusion Power instead of Mach 3 blade today. However the blade for Fusion is quite expensive... so in the end got the Mach 3 blade instead.
I never shave one just pull out the hair. CAn last for many days
using the free mach3 given by SAF...
eat. drink. shoot
After using the Gillette Fusion for some time already, I must say that it is much better than the Sensor Excel that I was previously using. Gone are the cuts and nicks that I use to get after shaving. But just that the single blade at the back is not really effective when shaving my sideburns.
Still using the old Mach 3 given by my gf during my JC days (many years liao)
Just splash water (from tap) and shave liao...simple and fast.
Been using Fusion power for over one yr, and i have to shave every single day
