I've had that haircut too Out, it's a styling nightmare to get it all to behave at least like everyone is getting along in the back.
Pupsie, there are a few videos about what to ask your hairdresser for and I think generally thinning out is not considered helpful. I've seen it done on one wavy person and it's her preference, but it just looks a bit odd in my opinion. It sort of hangs straight down like straight hair does (curtain like, maybe?) but then with waves iykwim. Whereas waves/curls tend to have some movement in the way it cascades down, it's really noticeable (in a good way) on out's picture where straight hair usually just sticks up slightly at the roots and then bends down along the face a bit like on Lego and Playmobil dolls 🙊 curly hair tends to frame around the face.
I do think you have to put a bit of thought to what suits your face. If you look at the big hair influencers they all have similar features, full lips, roundish or otherwise pronounced almond shaped eyes and often full cheeks, not so sharp noses or cut glass cheekbones and curly voluminous hair works well with that. Similarly I feel really weird with jet straight hair, it just doesn't mesh well with my face and I look really odd. Someone like Naomi Campbell on the other hand really suits that jet straight sleek hair and looks (still amazing, because Naomi Campbell) a little less special with other hair styles.
I remember looking for the pantene foam sometime ago but it's been discontinued here for a while not sure what the UK situation is. I had looked at the John Frieda one but then decided I don't want to use things with butane gas and would be sticking with foams. I assumed they were the same thing though but foams and mousses are not necessarily the same product group (so exhausting).
It should be washday for me today and despite warmer weather and upping the exercise intensity (with a very sweaty face) it feels like I can wait a day or longer even. I think it's down to the protein stylers as that's making it a touch drier and I tend to wash when hair gets greasy as opposed to my scalp being greasy.
Speaking of scalp, Quirky an interesting video popped up about it, seb derm/dandruff. Thought it was interesting she suggested washing more often (with dry scalp).
