  • So unlike hand soaps etc, shampoo is not trying to sanitize your hair. Washing is to remove dirt and grease, not necessarily kill microbes.

    Yes sebum is beneficial to the scalp. And yes stripping too much sebum from the skin (washing too often) can lead to dryness and irritation and dandruff symptoms.

    But dandruff can also be caused by fungus and bacteria, see the “Causes - > Microorganisms” section of the Dandruff Wikipedia article. The fungus mentioned here specifically feeds on sebum, so not washing enough to remove that sebum can cause that fungus to thrive.

    So yes washing too much can cause dandruff, but so can not washing enough (I linked this interview with a dermatologist in another comment, they say the same thing here.)

    There isn’t a one-size-fits-all answer here. But doctors do recommend washing your hair regularly - how regularly depends on a variety of factors.


  • Co-washing only (washing with conditioner and skipping shampoo) is highly recommended for folks with extremely curly hair.

    I tried it with my largely straight and thin hair and it was a disaster for me. But different hair textures require different solutions.

    Re: “all the after-products” Again, different hair types require different solutions. A heat protectant product (applied on damp hair after washing and before drying and styling) is really important if you’re using heated styling tools for straightening or curling your hair. Even moreso if you’re also coloring your hair, which can make your hair more susceptible to heat-based damage. Additionally, for certain hair types and cuts, styling products are absolutely necessary to achieve the look you’re going for. My hair won’t hold a curl without adding product to it before styling.

    As I say on another comment on this thread, my hairdresser does recommend that I shampoo twice on wash days to ensure I remove all the dirt/grease/styling product. Shampooing once (with my SLS-free shampoo) wasn’t getting my hair clean enough.

    So yes, including after-care products in your routine may necessitate different cleaning steps compared to someone who isn’t using the same products. But again, what you are doing with your hair and the type of hair you have also influences the types of products that are valuable for you to use (shampoo, conditioner, and aftercare.)

    All that said, claiming that haircare is all advertising “with a bit of social dynamics and zero science behind it” is misleading, uninformed, and incorrect. 😘

    Since you sound like you want science, here’s an interview with a doctor of dermatology.


  • Google tells me yes H&S does use SLS in the US, confirmed here On their US website

    I did see a Reddit thread as a search result that says H&S dropped SLS as an ingredient in Europe - the thread was from 11 months ago, but I also didn’t open it to check the details. And I haven’t watched the video so I don’t know what region this guy is in.

    Edit: rechecked the post and it looks like this guy stopped shampooing 7 years ago (so before H&S dropped SLS in Europe.) From my memory as a long-haired woman/regular consumer of haircare products, I would say concern over SLS started within the last 10 years. So potentially this guy in the video was making his decision to stop washing right around the time the industry was becoming aware of the risks of this ingredient. But again, that’s all conjecture based on my experience as a mildly informed consumer of haircare products lol


  • So admittedly I haven’t watched the video.

    But it sounds like this guy has a sensitivity to SLS - Sodium Lauryl Sulfate. It’s a cleaning agent in a lot of shampoos that can lead to skin dryness and irritation - aka it can cause dandruff.

    Cutting out that chemical by not shampooing anymore would help… but also these days most (more expensive) shampoos have dropped SLS as an ingredient because it’s a skin irritant for most people. So he probably could have just switched to a different shampoo.

    If I remember correctly, SLS contributes to a good lather: the shampoo getting foamy so it’s easy to spread around your whole head/all your hair if it’s long. So SLS-free shampoos are a bit less foamy. My hairdresser recommended that, on wash days, I shampoo twice with my SLS-free shampoo to get a more thorough clean. However, I do not wash daily; I wash my hair every 3-5 days depending on how much I’ve exercised and whether I’m home or in the office on days 4/5.






  • This reads like a Rimworld post.

    I don’t think there’s a Rimworld community on Lemmy and I’m not going on Reddit anymore so I’ll just throw this comment into the void and hope some fans are out there. 👋

    Also in Rimworld terms the answer is corn (if monoculture) and send everyone to harvest at the first sign of blight.

    But in both Rimworld and real life, a monoculture strategy isn’t sustainable. Diversifying via multiple food sources reduces your risk of disaster leading to starvation.



  • This is hilarious.

    My husband runs our Lemmy instance, and he’s subscribed to the Linux community, which is one of the most active on Lemmy (I probably don’t need to tell you that.) I’m basically just here for memes and I ultimately blocked the Linux community because it was all over my feed. I’m a normie and I just don’t care about Linux whatsoever, not enough for every other post to be about it anyway.



  • I agree. I was in college at 19 and I would not have been able to grow as a person in the same way, if I had been dating a 25 year old at the time. You’re just at different stages of life at this point.

    I’m not saying it’s impossible for this to work out well for some people. Clearly in the comments here it has, and I have friends with a greater age difference who are now happily married.

    But in general, no I don’t think this is a good idea. If it was the same age gap but meeting later in life, no big deal. But a 19 year old is at a very different point in life than a 25 year old and she needs to be able to grow on her own outside of a relationship with an older person.



  • Hey, I work in QA (not in the video game field though.) However, I can tell you there is a difference between “QA missed” and “deadlines required prioritizing other fixes.”

    One implies that the employees are bad at their job. Which is almost certainly not the case. I haven’t played Starfield (or even clicked through to your link lol) but presumably this is something blatantly obvious. And I’m sure the QA team was frustrated letting a glaring known issue through.

    QA finds issues but it’s up to development teams to fix them, and strict deadlines will always hamper delivering a flawless product. But deadlines are driven by management and until the industry changes (i.e. don’t preorder games) we’re going to keep seeing these problems.

    But as a QA professional, please don’t blame us ✌️
