How can I give my hair a bit more oomph?

[Sonolanona]

Should length hair with a middle part and sort of grown out fringe (so long layers). It's naturally wavy/frizzy so I straighten it twice a week and try to stay out of the rain !
But the parting is limp, it just flops around my face. I can't have a fringe as have a wicked cowslick. My hair is about the length of this picture , naturally grey and brown and I'd like it to look like the pic..mine just flops if staightened and frizzes if not!
What products would help? (and how do I use them?!)

i Thought that pic was you to start with and was thinking this is some humble boast 😁

I am far from an expert, but my hair has been so much better since I embraced the wave it has rather than it just being annoying and neither straight nor anything that resembled a style.

I use Merwave and it’s been a bit of trial and error but I honestly love my hair now. They have a fb page too with lots of tips. Good luck!

Style on Steroids. Honestly, you'll never look back.

Fudge do a volumising spray. It really is very effective.

100% this by Color Wow - it’s an obsession I cannot live without.

some of the younger girls I work with told me I have a signature bouncy blowout look (and it’s with v little effort!)

Yes, I've had similar comments - "wow - your hair's so thick/bouncy/full" etc..

I actually have quite fine hair - just lots of it.
