I'm so sorry, hun. Sounds frustrating. I don't like to apply too much product to the crown either. Flattens me. And the hair there is new and doesn't need as much moisture or aid. I love to diffuse upside down. Why did you stop? Thanks to the meza video, when I do diffuse (I mostly air dry since it's summer), I toss my hair left (gently), pixie diffuse, toss it to the right (gently again) pixie diffuse. And then down. Three rounds then I'm done. I just am wayyy more careful than her and much more brief, however. Hopefully diffusing upside down again will work out but if not at least you have a backup.
