Hair color on bottom, also known as underlights, is a hair coloring technique where the bottom layers of hair are dyed a contrasting color. The top layer of hair is left its natural color or dyed a complementary shade, creating a peek-a-boo effect. This technique adds depth, dimension, and a touch of edginess to any hairstyle.
Underlights are a versatile hair trend that can be customized to suit any taste. They can be subtle or bold, and can be used to create a variety of looks, from ombre to dip-dyed. Underlights are also a great way to add a pop of color to dark hair without having to bleach the entire head.
