What is the technique called that involves the gradual lightening of hair?

The technique known for the gradual lightening of hair is commonly referred to as ombre. This styling method creates a smooth transition from a darker shade at the roots to a lighter shade towards the ends, providing a natural gradient effect. The hallmark of ombre is its blend that allows for variation in color while maintaining dimension, resulting in a beautiful and contemporary look.

In the context of hair color techniques, ombre differs from others in that it specifically emphasizes a more pronounced transition from dark to light, often resulting in a striking contrast. This technique is particularly popular for its low maintenance; as the roots grow out, the darker color becomes less noticeable.

Other techniques, such as balayage, also involve lightening hair but do so through hand-painted highlights that offer a more sun-kissed and natural appearance without the stark contrast seen in ombre. Highlights typically involve adding lighter pieces throughout the hair, while dip-dye is generally characterized by a more drastic, block color application at the tips of the hair. Each technique has its unique style and application method, but for gradual lightening specifically, ombre stands out.
