How do I check if hair is light enough when bleaching?

Answer 1

To check if your hair is light enough after bleaching, examine the color against a swatch or guide that matches your desired shade. After the recommended processing time, rinse a small section of hair to see if it reaches the desired lightness; if not, you can bleach it again. It's essential to avoid over-processing, as this can damage your hair, so always assess carefully before proceeding. Additionally, consider the undertones; hair should typically be a pale yellow or lighter for optimal results.
