Which of the following characteristics apply to 30 volume developer?

The selection of 30 volume developer is primarily due to its ability to achieve up to 3 levels of lift. This developer is often utilized in hair coloring processes where a significant change in hair color is desired, especially when going from darker shades to lighter shades. The lifting capabilities of 30 volume make it suitable for techniques that require more noticeable lightening effects, such as highlights or overall color changes.

Other developers, such as 10 or 20 volume, generally lift less and are better suited for depositing color without much lightening. Additionally, while demi-permanent color may be used with lower volume developers, it does not typically require the higher lifting ability offered by 30 volume. Similarly, corrective color applications might involve varying levels of developers depending on the specific needs of the hair and color history, further indicating that 30 volume is best known for its capacity to lift hair color effectively.
