Bummer. Note-to-self: Don’t use 3rd party addons for tutorials anymore 😅
The only thing I remember using sculpt tools for in this video was extracting from a mask. Good news: This feature is being built into 2.81 I believe! But for now, to accomplish this without the tool, I recommend creating a sphere and manually sculpting it into a hair scalp shape, then pickup in the video with inflating the large curls.
Same for the eyebrows, I’d create a pair of cylinders and dyntopo-sculpt them into shape manually.
