During the prologue, you’ll be tracking down moths to get Grandma out of the house. The braided hair music puzzle is one of them. You can also get the Meticulous Hairdresser trophy here as well by cutting off the 6 errant hairs, one on each braid. In the picture, one example is circled in blue.

When you start, the notes you need to mimic will come down the left side of the screen. If you miss them, just tug on 3-4 braids and it’ll repeat them.
The first set is red, blue, green. You can also tell which one because the music notes are different for each color. The yellow one is circled in red as an example.
For the second set, the game will add two blues. So you’ll do red, blue, green, blue, blue.
For the third set, the game will add purple and yellow. So you’ll do red, blue, green, blue, blue, purple, yellow.
