Preparing the Hair
I started with a frontal from a beauty supply store. The hair needed to be prepped before bleaching. This involved carefully removing the hair from the frontal and trimming it to create smaller pieces resembling closures.

To prevent the hair from bunching during the bleaching process, I sprayed it with Tresemme holding spray and brushed it back. This ensured even bleaching and prevented tangles.

Protective gear is crucial. I emphasized wearing gloves at all times when handling bleach to avoid skin irritation and damage.

Mixing the Bleaches
I used one scoop of each bleach powder: Kiss Lift Up, Quick Blue, and BW2. The consistency is key. I used 30 volume developer for a yogurt-like consistency, not too thick, nor too runny.

For the Kiss Lift Up bleach, I emptied the entire remaining package because it had only a small amount left.

Adjusting the developer is acceptable if needed to achieve the desired consistency. If it becomes too chunky, add more developer.

Bleaching Process
I applied each bleach mixture to a separate closure using a brush applicator. I used a lighter hand for application, but since these were beauty supply closures, I used a slightly heavier hand due to the knot's resistance to bleaching.

Each closure was wrapped in aluminum foil to maintain heat and promote even bleaching. The bleaching time for each was 30 minutes; I did not check them during the process.

After the bleaching process, I used blue shampoo to tone out any brassiness or orange tones from the bleach.
Results and Review
The Kiss Lift Up (blue-based) didn't deliver the expected results; I found orange spots on the lace, which was not acceptable for a blue-based bleaching powder.

Quick Blue (blue-based) provided a clean bleach; resulting in an even, lightened base ready for further customization. It showed excellent scalp coverage and minimized the need for excessive makeup or tinting to match a client's skin tone.

BW2 (white-based) bleached well but left an orange and brassy tone, requiring more effort for color correction to achieve a natural, blendable result on various skin tones.

Conclusion
Based on the test, Quick Blue emerged as the superior choice for bleaching knots. Its blue-based formula provided an even, lightened base, easily customizable to various skin tones. It minimized the need for color correction and offered the best overall result for seamless integration into any client's hair.

While BW2 and Kiss Lift Up bleached the hair, they left undesirable tones that required additional work, impacting overall efficiency. The Kiss Lift Up performed particularly poorly in this aspect.
For professionals and those seeking a superior bleaching experience, Quick Blue is the clear winner, offering excellent results with minimal effort and time.
