Initial Assessment and Preparation
The process began with an assessment of the model's hair. It was naturally dark, with previous black dye that had grown out significantly. The goal was to lighten the hair to a blonde shade using L'Oréal Colorista Bleach. Necessary tools and protective gloves (recommended from personal experience) were gathered for a successful application.
Application and Mid-Process Observations
The bleach was applied meticulously to the top section of the hair, focusing on the areas needing lightening. A Florida storm was brewing during the process, adding a bit of unexpected drama. The video shows the application and the immediate visible effects of the bleach on the dark hair.


Results and Post-Process Analysis
Once the bleach had processed, the results were mixed. While the previously dyed black portions lightened significantly, some black dye remained, suggesting the need for a color remover like Color Oops for a more thorough transformation. The newly lightened areas showed a decent blonde shade, although not perfectly even. The overall transformation was partially successful.

Conclusion and Product Assessment
L'Oréal Colorista Bleach showed some promise but did not fully deliver on its advertised results due to pre-existing black dye. While it significantly lightened the hair, a pre-treatment with a color remover would have been beneficial. For a complete black-to-blonde transformation, multiple applications or additional products might be necessary. The product is usable but its effectiveness is dependent on the hair's initial condition. The need for a second box of dye to finish the look underscores the limitations.
