How to make hairstyle (hair swept to one side like this pic) stay perfect without becoming a MESS?

[LightningOne]

Hi ladies,
Saw an article about Michelle Keegan the other day - her hairstyle looks amazing here:

My question is, is it possible to have hair remain looking like this for an 8 hour day?? I've tried and the minute I bend over to pick something up, etc. my hair is a total mess and the parting completely changes. I've tried using clips at certain points to try and make it stay but that ruins the hairstyle.

Any tips or ideas from experience please? I've not tried hairspray on it yet (mainly due to sensitivity to chemicals in it) but will keep that as a last resort if nothing else works.

Thank you

Backcombing and hair spray- and no it won't last all day
I would expect to 'jush up' every time I went to the bathroom ...

I blow dry my hair upside down, put it in a loose twisted bun at the top of my head overnight, straighten in the morning, bit of hairspray and the volume lasts all day!

@anothernewone @Bigonesmallone3 Thank you for both your responses.
I'm not having a problem maintaining volume lol if anything I have the opposite issue. Even the slightest humidity/rain will make my hair poof up into a massive frizz ball (think Monica from Friends in that episode where she went on holiday lol) so was asking more about how to get hair strands to stay where they're supposed to be rather than hair becoming flat :)

I'd be more inclined to just blow dry it (upside down is a good idea as PP said) and straighten it very smooth, then just keep swooshing it over to one side as you go about your day and let it fall naturally. It's not the type of hairstyle that would look all stiffly hairsprayed I don't think.

Yeah, you need hairspray to make your style last. That’s why your hair gets frizzy or loses it’s style throughout the day.

I think her hair looks quite basic, so easy to achieve with a combination of a bouncy blow dry, a bit of backcombing and hair spray. You should blow dry your hair in the side you want it parted, so it drys and stays in that parting throughout the day

Also as you mentioned Monica, is your hair naturally wavy? If so, your hair needs more serum/moisture to prevent it from reacting to humidity as much and becoming frizzy. Your hair does that as it’s absorbing the moisture from the air as it’s lacking the moisture it needs to begin with.
