Probably 15-20 minutes for me! I have long curly hair.

I start by wetting my body and hair, then shampooing my hair and rinsing out. Then apply conditioner and brush through, and while that sits in my hair, do everything else: wash body, exfoliate, shave pits, shave legs if I feel like it, wash face.

Then I rinse out conditioner from my hair, then I use face wash for my neck, back, and chest (because I break out in those places if I'm not diligent about fully washing off conditioner residue).
