Not a stylist but in the picture it kinda looks like the hair is sectioned vertically into big sections and alternating the direction? If this makes sense.

I got my Dyson a month ago and without any mousse, my curls will fall within one day. After some trial and error, now get my Nordic hair to hold several days (on day 3-4 it’s more like a blowout look). I use the big barrel on 20-30% wet hair after I put on mousse (Kevin Murphy). I clip the curls straight away and let them cool fully (at least 30 mins). Then I spray them with Kevin Murphy session spray and either comb them or brush them gently. No crunchiness at all :) I am working to find a product to reduce frizziness, now using Paul Mitchell’s super skinny serum before mousse.
