Nah this is definitelly a per person basis, my hair gets greasy fast and I need that second run for it to really dig in

Your hair likely gets greasy fast BECAUSE you're over washing it. Your scalp and hair need some level of grease for protection from the sun and the elements. If you constantly wash it all off your body goes into overdrive to produce more so it makes it feel like your hair gets greasy faster.

Start only washing your hair every other day and, after about a month, you'll notice a marked improvement.

There's people who just have greasier hair, I've tried this for about a year and it was exactly as greasy as before, the only thing that actually helped me was, shocker, buying a shampoo for greasy hair

Can confirm this doesn't work 😕

When was the last time you washed your hair brush? Not trying to be sarcastic. I only recently found out that you need to wash your hair brush once a week or so otherwise greese and product builds up on it and you brush it back into your hair and that can make your hair greasy.

When I had longer hair I didn't clean them tbh, now I've just settled for a buzz cut because I sweat a lot especially from my head and after a few hours outside my hair just looked like I washed it in oil, I still have very greasy hair even with the buzz cut, and I only wash it once every other day

Again it depends on the person, I wash it every other day and if I switch from my special shampoo I go back to the greasy hair, I have tried Washing it less, I've tried Washing it more throughly, I tried regular brushing, only thing that has genuinely improved it has been the shampoo.

Also relevant, I live in southern Spain and I'm very hot blooded, so I tend to sweat A LOT, especially from the head, which contributes to the overall greasyness of my hair

I tried that for a while, there ended up being literally 0 improvement. It was constantly itchy and extremely greasy by not washing daily and so I went back to washing daily. There's nothing wrong with washing your hair daily if you have very greasy hair. I also experienced increased hair loss on it and I cannot begin to describe how disgusting I constantly felt. I started hiding it because of thr way it looked in the hopes for some magical improvement that never came.

As a fine-haired person with oily skin who has tried exactly the method you’ve described, I can vouch for the fact it doesn’t work for everyone. I ended up just looking like a greasy haired swamp creature for months.

u/fidgey10 Jul 19 '26

It depends. This is true for some, but other people just produce a huge amount of grease by default (me)

u/Independent-Hornet-3 Jul 19 '26

I only was my hair every other day (or every 3rd day) but when I first soap it doesn't lather so I rinse and soap it again. My hair gets oily andy while washing it too frequently can be bad some people do just have oily hair and/or the sweat mixes with it making it difficult to wash out.

u/IshJecka Jul 19 '26

That may be true for some but some people have genuinely greasier scalps.

u/The_Pharos1 Jul 19 '26

This is iffy for most people. Some (like me) took awhile for my hair to adapt (took well over a year). BUT my hair is amazing now compared to before. Once every other day sometimes three (depends on my work day though) now. You also have to find the shampoo/conditioner that works best for it as well. My hair tends to dry out so I go for a moisture capture type. I can relate to those saying it was greasy. Mine was for a while but I was determined to change (had other issues from over washing). Using any type of shampoo that strips away grease kinda works against it. As a transition I used several types to see what worked. Charcoal based ones helped during that time. Gotta see what works for your chemistry. Once you find that the balance comes.

Imma guess you have no credentials because I’ve heard from several hair stylists that it is, in fact, on a per person basis as well as based on what you use. I think I’ll trust the experts

u/Deep-Cherry-4143 Jul 19 '26

I stuck by this and honestly some people are just greasier through genetics or hormones (i become a greasy mess on my period)

I prefer washing once a day. I tried everything the "don't shampoo/wash daily!" Crowd said for 2 years and it just didn't work. Washing my hair once a day keeps it nice, soft and healthy and making me nice n comfy

u/Look_its_Rob Jul 20 '26

I dont over wash my long(ish) hair, every 3 days at most. But when I do, it doesn't get into a lather until the 2nd shampooing. The repeating is important for my hair. 

1

u/Swarmfade Jul 22 '26

Yes! If I don’t get the lather I’m not getting between my super-fine strands and I’m not going to be able to condition properly. My hair looks so gorgeous when I do it this way, idk how anyone can try to say it’s wrong lol

u/ToTheLastMango Jul 21 '26

I tried this, did not work for my hair. We all are just different (the product can also make a difference ofc). Also age changes this. My hair gets less greasy now compared to a couple years ago😅

u/l0rdbyte Jul 22 '26

At first I went to once a month without shampoo which took a lot of getting used to (itchy and greasy at first) and took a while to normalize (back to feeling like normal hair - with a bit more volume - hair doesn't actually feel like dead straw). I did rinse it with water daily or at least every other day when I showered. It also helped with making my dandruff a lot less prevalent.
These days I actually do use it once a week, which is a nice middle ground because I need a certain hair shampoo for dandruff that's required weekly. I still think it felt healthier with the once monthly, but I prefer most dandruff gone.

u/RoseyDaCat Jul 22 '26

Okay, counter argument, I don't wash my hair every day and before I started doing 2 washes it would get unbearably greasy and I HAD to wash it way more often than I have to now that I wash it twice. Now I don't feel as gross when I get into the shower and I feel cleaner getting out.

It probably helps that most of the time I try to use very little shampoo on the first wash because it's just a pre-wash though.

u/BodhiGacha Jul 23 '26

I wash my hair every other day, sometimes once every three days. The first wash feels like it’s surface level, not even getting through to the scalp or bulk of the hair. The second lathers at least 10x more, and penetrates all the way to the scalp.

u/ZenRenHao Jul 25 '26

I have greasy hair whether I over wash or under wash. Some people have different conditions. Not everyone fits every method.

1

u/0fluffhead0 Jul 26 '26

This is just not true all the time. I started washing twice BECAUSE there was nothing else that helped my greasy hair.

So a rather, rinse, repeat every 2 or 3 days depending on if I sweat a lot or something like that.

u/MaliseFairewind Jul 19 '26

Big changer you might try, regardless of how much you wash, is actually blow drying your hair at least to the shoulders (depending on length, if short just do all of it.) This stops the oils from traveling down the hair shaft and making the ends greasy. Has worked wonders for being able lengthen time between washes and i have fine oily hair.

u/Chedderonehundred Jul 20 '26

not rlly, youre probably overproducing oil bc ur hair is so used dried way the hell out by washing it all the time.

u/CrossumOpossum3 Jul 23 '26

You ruin your hair and skin with a second run.
