Well this week (19 August), Jessie let her Instagram fans in on the secret to her fabulous locks when she posted pictures of her latest favourite hair products...
First up came L'Oréal Professionnel Play Ball Beach Fizz, £11.99, lookfantastic.com which Jessie loves so much, she practically wrote a whole essay about it!
"Ok so I have a new found understanding for how much boys went through at school getting the texture of their hair right..." Jessie posted.
"It's hard to get used to. Gel? Wax? Sculpting putty? You wouldn't believe how much there is! This is one of the hair products I have found that I really like. So I thought if any one else is struggling with getting there hair to stay down lol I should post this!"
"It smells nice too. Please believe some of them smell like doo doo. Woof!"
Thanks Jessie, we couldn't have put it better ourselves!
And the 'Wild' singer didn't just stop there, giving her fans yet another recommendation for achieving Jessie J hair.
The other product she adores is Bumble and Bumble Leave-in (Rinse-out) Conditioner, £20, bumbleandbumble.co.uk.
Yes, we thought that too – how can a conditioner be 'leave-in' AND 'rinse-out' at the same time?!
Well it turns out you can do both with this little beauty. Either leave it in damp hair to tame frizz and soften your hair, or rinse it out in the shower as you would a normal conditoner.
Now that's the kind of multi-purpose product we LOVE!
