01
Root touch-up and full-head color need different amounts
A root touch-up covers a smaller area. Long, thick or dense hair and first-time full-head coloring require much more product. Check the amount guidance supplied with the product before starting.
02
Do not ration halfway through
Spreading the remaining product too thinly can leave the hairline, back of the head or ends under-covered. Prepare enough product before you begin.
03
Can leftover product be saved?
Storage depends on the product and its instructions. A mixed product that has begun reacting usually should not be sealed and saved for another use.
