I'm not sure. Maybe a longer hair with more exposure is easier to hydrate before the shave, so it becomes a little softer?Why do you feel that your shaves are closer after a few days growth?
(Just an engineer's enquiring mind.)
I don't know why, but I get a better shave with two or three days growth compared to only one day. In terms of closeness, a few days growth is the same or maybe very slightly closer than one day growth, but for some reason it's an easier shave overall. Intuitively this doesn't make any sense because as you say @rbscebu you're cutting at skin level - the edge doesn't know how much hair is sticking up past the skin. But thinking about it a little more I have a few ideas:
Better hydration seems like the most likely reason to me.
- There isn't actually any difference at all, it's just an emotional response to the satisfaction of wiping away more stubble than normal.
- Longer whiskers are more hydrated and therefore softer and easier to cut. A longer whisker holds more water, and this acts as a reservoir to hydrate each whisker at and below the surface more effectively than a short whisker. They continue to hydrate deep down until you cut them off with the first pass.
- Longer whiskers support each other so they are sticking out closer to 90 degrees from the skin. Shorter whiskers are closer to parallel with the skin which makes them mroe difficult to cut. It might only be a few degrees of difference but it could be enough to make it an easier shave.
So not much science involved here, but more anecdote. Well, i guess i do attempt to explain it with science. I grew up on a farm in NC, and as a small kid I had a number of mundane hobbies. One of them, with my cousins, was to knock over tobacco and sweet corn stalks after all of the leaves or ears were harvested. Tobacco stalks were bare, and around 3-4 feet tall. We would swing sticks at the base of the stalks, and they would break and fall when struck just right.
Now tobacco and corn stalks were always mowed after harvest, and then the roots plowed up. This helped to prevent diseases from being trapped in the soil. So essentially, no one ever grew angry because we played in a field that was about to be mowed anyway.
On to the story. When we were in a field with standing stalks it was fairly easy to swing a stick and completely sever a tobacco stalk at the base. Occasionally, we would play this game after the stalks had been mowed, when they weren't 3-4 feet tall, but only 6" tall. There was still enough stalk left to make a suitable, though more challenging, target. I can't recall anyone ever being able to sever these shorter stalks. The mass of the longer stalk provided enough resistance to offset its "flex." The shorter stalks would often Crack the earth and ground once struck squarely. Sometimes they would break. But they would never sever.
Corn stalks would never sever completely. They are tougher and more fibrous. But we could often hit them hard enough to knock them over if they had yet to be mowed. After they had been mowed, we could do pretty much no damage to corn stalks by swinging a stick at what was left.
I know this is a convoluted anecdotal story, but there is a point. Tobacco or corn stalks are the same diameter at the base whether they were 6" tall after mowing or 6' tall (in the case of corn stalks). The taller ones were much easier to knock over and sever by swinging a stick. I think this is a similar principle as to why longer hair does, in fact, shave a littler closer or easier than short stubble. The mass of the hair helps to keep the root from flexing and resisting being cut. At least that is my theory.
All of this effort in explaining, yet sometimes I think it is actually easier to shave daily. Go figure.
I also used to think that length of your whiskers do not matter. I thought that it was the length of hair below the skin that counted. . Your length of whiskers plays a key role in determining your shave smoothness. Shaving with long whiskers is harder than shaving with short whiskers. It is more difficult for the blade to cut through longer whiskers than the shorter ones. So, yes, it is true that longer whiskers are more challenging to cut. But you can always use a stronger blade and make it easier to cut. The answer to your question lies in the coarseness of your whiskers. Short coarse whiskers can be handled both by coarse and fine blades. So, shaving with coarse whiskers is easier than with fine ones.I have never been able to find out myself if longer whiskers are easier, harder or the same to shave. I don't have the willpower to go for longer than about 24 hours between SR shaves.
Many on B&B state that they let their whiskers grow out to "test out" the edge on their SR. I can't see that there would be a difference. After all we are only cutting our whiskers at skin level. The length of whiskers above the skin shouldn't come into it.
If you think there is a difference, please state which and why.
Can you please have a go at explaining why this is so?.... Shaving with long whiskers is harder than shaving with short whiskers. It is more difficult for the blade to cut through longer whiskers than the shorter ones. ....
I am not surprised. I think that it may be more psychosomatic.I am surprised to learn that some think that longer whiskers are easier to cut, and some find short stubble is easier.
I never thought of that. Good point.With straights length makes no difference WTG.
But with a little growth,
ATG your edge is also encountering the tips of whiskers from upstream
at the same time as the base of the whiskers which are actually being shaved off.
