When lightening hair, what sectioning size should be used?

Using a sectioning size of 1/8 inch is ideal when lightening hair because it allows for more precise application of the lightening product. This finer sectioning helps ensure that the lightener can properly penetrate the hair strands and reach the desired level of lift. The smaller sections promote even distribution of the product, which mitigates the risk of uneven lightening and patchiness, both of which can occur when larger sections are used.

When hair is sectioned too thickly, the outer strands may lighten effectively, while the inner strands might not receive enough lightening agent, resulting in a discrepancy in color and tone. With 1/8 inch sections, the stylist can work methodically through the hair, ensuring that every part of the strand is treated adequately. This technique is especially important in achieving consistent results in hair lightening services, where precision is key to client satisfaction.
