The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

I’ve often been told that this isn’t actually true but I can’t help but feel that it does happen. Until recently I hadn’t shaved for about a year, maybe two. Now I feel like it’s growing back quicker than what it did the last time (after shaving on a more regular basis).

It doesn't, it's just that going from zero to 1/4" inch of hair is a lot more noticeable than going from 1 to 1.25 inches.

Also the newly cut edge is sharper and feels more than a 3 week old bristle.

That's what she said

It doesn't, it's a perception bias caused by a few different things like others here have mentioned, but also freshly grown hair tends to be thicker, then tapers off as it grows, so it SEEMS thicker.

The rate at which your hairs emerge from their follicles is constant, but the rate of increase of the total length of the hairs slows down and eventually stops because the hairs naturally wear down over time.

Imagine that your hair is like pasta being extruded into water, and that it slowly dissolves over time. The more time the pasta has been in the water, the faster it dissolves—and it eventually reaches an equilibrium length where the tip is dissolving as fast as the other end is being extruded. But if you cut off the pasta at the extruder and time the new pasta coming out, you’ll measure the full extrusion speed instead of the extrusion speed minus the length-dependent dissolution rate.

Finally the mathematically correct answer! Thank you for typing this out

If youre in your 20s or 30s, its entirely possible your beard grew back faster compared to a year or two ago. But thats because of getting older and stuff like that. Your beard doesnt grow faster just because you shaved recently.

[–] philo@lemmy.ca 17 points 4 days ago

It doesn't. The growth is the same. The perceived difference is because the ends of the hair are straight and uniform rather than all raggedy. People have been asking this for years and have been hearing this answer for years but for some reason keep asking the same question over and over.

AFAIK, apart from drugs, only stress and malnutrition affects hair growth speed. Stress can increase cortisol levels, which can lead to faster hair growth, but chronic stress and malnutrition may lead to hair loss.

[–] CountVon@sh.itjust.works 12 points 4 days ago

I don't believe it actually does grow back faster, it just seems that way. The first inch or so gives the impression of growing back faster because the hairs are thicker at the base so they're more visible and less prone to breakage.

As a transgender woman, I have personally experienced that hormone replacement therapy (HRT) -- which includes estrogen as well as testosterone blockers -- slowed down my facial hair growth and thinned out of my facial hair. So testosterone levels play a small part in facial hair growth. However, I doubt that the levels within a cisgender male would vary enough to cause any significant changes.

It's probably just that there's a fair bit of hair growth that happens before the hairs reach the surface of your skin, like a millimeter or two. When you shave, it only has to grow back enough to pop out over the surface of the skin. If you were to pluck a hair with a pair of tweezers, it would take at least a couple of weeks to grow back. I have done exactly that many times, so at least for me that's the time frame.

It may well be growing faster as you age. Mine certainly did.

[–] HobbitFoot@thelemmy.club 2 points 3 days ago

I've just found that beard growth is easier for me in general as I've gotten older.
