Final answer:
A powder lightener without buffering agents and conditioners should not be used for an all-over color procedure due to the potential for hair damage from the extensive application involved.
Step-by-step explanation:
A powder lightener without buffering agents and conditioners is typically quite strong and may cause damage to the hair if used incorrectly.
Given this, such a powder lightener should not be used for an all-over color procedure. Balayage, foil highlighting, and root touch-up techniques often involve more controlled application processes where the lightener is not applied as extensively as with an all-over color.
During all-over color applications, the lightener would be evenly distributed throughout the hair, and the lack of buffering agents and conditioners could result in increased potential for damage, making this type of powder lightener unsuitable for such a use.
A powder lightener without buffering agents and conditioners could NOT be used for All-over color.
This is because when performing all-over hair color, the hair needs to be lightened first to achieve the desired shade.
Lighteners like bleach are used to lighten the hair before applying the color.
Balayage, foil highlighting, and root touch-up procedures also require hair lightening, so a powder lightener without buffering agents and conditioners could be used for those procedures.
