What size partings should be used for on-scalp bleach application?

The correct choice reflects the recommended size of partings for on-scalp bleach application, which is typically 1/16 of an inch. Using a fine parting allows for better control and ensures even application of the bleach. It helps in saturating each section fully, minimizing the risk of missed spots that might occur with larger partings. Fine partings are particularly important when working with more delicate applications like on-scalp bleaching, as they allow the product to process evenly throughout the hair and reduce the chances of overheating the scalp. Additionally, this precision can lead to a more uniform lightening effect and healthier results for the hair and scalp during the bleaching process.
