To think that "training" really greasy hair just isn't possible for some people?

I don't think this would ever work for me, either! I have lots of very fine hair and the most I can sort of get away with is maybe 2-3 days max without being washed such as if I'm not feeling well due to illness/injury or the like, but after a day of not washing it quickly starts to look very greasy/limp/difficult to do anything with and my scalp gets really itchy too...as long as I wash it every day, that doesn't seems to happen.

Also suffer from hay fever and work in a job where I'm regularly exposed to bodily fluids and the like....who wants to go to bed with unwashed hair after being around that all day!?

I also have really oily scalp. I rebalance it every month or so by putting t gel shampoo for dandruff/ flaky scalp and leaving it for about 10 minutes. It seems to work for my oily scalp as well as just being for dandruff

YANBU. It entirely depends on hair and skin type. I have greasy/combination skin and fine, straight hair. No amount of training is going to stop it looking awful on day two. I don't see any need to train hair like mine though. It's quick and easy to wash and dry so I'm happy to just do it daily.

Some people have greasy hair....just like some people have acne. I'm one of those people.

The longer I leave it, the greasier it gets and the itchier it becomes.

I can go 2 days. On the second day I use dry shampoo 😫

I was once housebound for nearly two years due to illness. My hair was washed for me once and occasionally (joyfully!) twice a week. It was never trained. Still a greasy mop by the end of day two. So I totally agree with you - it definitely depends on the hair.

So everyone with Afro hair smells then you’re saying?
my hair doesn’t smell after 1 day or 2 days of not washing. I protect it when I cook and at night. It doesn’t get greasy

People who don’t wash their hair every day - you can smell it ! Maybe you don’t realise but your dirty hair smells !
It’s so unhygienic .

I’ve never managed it, it’s never settled and I just accept washing it daily now

It didn’t work for me.

It used to my hair about 3 days to settle down after washing it, so I washed it twice a week. I found the right shampoo which made all the difference. After having each baby it got far greasier but settled down again.

I managed to move mine from very 2 days to 4 days by extending during covid.

I've long thick hair which use to be greasy at the roots and dry otherwise.

I asked my hairdresser about it and she said my hair needed shampoo for dry hair & there was no point trying otherwise.

I only use conditioner on the ends every second time.

I dry it without any product other than heat protector.

I don't use dry shampoo, could problem get a 5th day if I did but it feels unhygenic not to watch it on the 5th day.

I wouldn't have thought it possible but it works.

Hormones go nuts when I'm on my period so every second day that week but it doesn't need a wash every second day otherwise.

The whole ‘resetting’ your hair thing has been proven to be a fallacy. If you have greasy hair there’s nothing you can do about it (other than taking Accutane which dries up your pores) or as pp have said, going through menopause!
Have you tried dry shampoo? I wash my hair every other day and dry shampoo in between.

Now my hair is very short, I can go every other day if I use dry shampoo in between. I use a Rituals one which isn't cloying like the cheaper supermarket ones, and Living Proof is another better one.

I think you probably can - if you’re willing to look minging (and probably stink a bit) for as long as it takes. Fellow greasy head here too and it’s not something I’m willing to do…so I’ve made my peace with washing it every day.

They sound very rude!

But as you said, you only have to wash yours every few days. I’d be more than happy with that.

No! How annoying! Have you tried the apple cider vinegar treatment? You rub a tablespoon in, then shampoo out. Not suitable if you've got a very sensitive scalp, though, it's quite astringent.

Just wash it. My dd goes to great lengths to only wash hair once a week - dry shampoo, slicked back with hair mask at end of week. Just wash it, it would look nicer and fresher. It’s like emperor’s new clothes I think they are sucked into this on tik tok etc.
I’ve got nice thick hair wash it every few days. If it’s too much of a faff washing your hair your hairstyle isn’t right for you.

If I wash mine in the evening it’s greasy by the next morning!

It's a myth. Your oil glands aren't reactive. Eg if you stop washing your oily face it would jsut get oilier and spottier. The only reason this might work for people is either they aren't putting as much conditioner on their roots so they get less greasy that way, OR they just get more used to having greasy hair.
The only thing that makes it so I don't have to wash my hair daily is the contraceptive pill.

Yes. That doesn't make a massive difference in my experience

I’m cursed with greasy hair and every fucker I encounter seems to have some comment they must make on it.

I wash it every day because if I don’t it gets limp and feels horrible. I’m happier with clean hair. I don’t care if others want to tell me it’s greasy because I wash it daily. I’m still going to wash it because I feel better that way.

try a clarifying shampoo like head and shoulders or Tigi detox.

Mine would be awful if washed more than once or twice a week. Same with Afro hair, you’re talking once every 1-3 weeks depending on how it’s styled

for me it’s the drying. Using a Dyson hairdryer and diffuser it’s around 40 mins to about 70% dry. An hour if I want it totally dry

Thanks. I actually have to use a medicated shampoo every time I wash it now or I get scabby weepy lesions. I wish I'd never tried to fix my hair as it only made my life harder.
