Step Ten: Group your layers.
This step isn’t really part of the technique, but more for helping to keep your layers panel less crazy!
On the layers panel, select the layers you’ve been working on (base layer, highlight layers, lowlight layer) by swiping right. You’ll know they’ve been selected when they turn blue.
Then tap ‘Group’ (in the top right of the layer panel) so that these all get added into a new section labeled ‘New group’.
Tap the ‘New Group’ layer to bring up the group options, and then select ‘Flatten’. This will merge all of the layers you’ve worked on into one single layer, which will keep things tidier as you work through the process above for the rest of the hair.
Once flattened, it’s hard to work with these layers and edit them as all the effects and colors have been merged together, so please don’t group and flatten your layers until you’re happy with how things look.
