Highlights are generally done with foils, papers or painted on free-hand.
You can achieve a subtle result of “sun kissed” or a little depth — to WOW!
What a change! Most highlights are very personal and combine one or two
of the following creative techniques:
>> Slicing >> Weaving (fine, medium, heavy)
>> Back to Back
>> Slice weaving
>> Painting 
There are 3 choices for highlight / lowlight:
Full highlight/lowlight — foils are placed throughout the entire head, this
is often a once or twice a year service.
Partial highlight/lowlight — foils are placed on top of the head, in the
crown and around the face, or a large number of foils are placed only on the
top of the head. The partial is the most common highlight service — it
allows a change that most often looks a little more natural.
Top/spot foils — between 2 to 10 foils are placed in personally selected
areas of the hair to add a little sparkle, or along the part to tide over a
“grow out” until the next partial (for those clients who just can’t quite
go the recommended 8-12 weeks between foil appointments). Great low
maintenance service!
