IMPORTANT GUIDELINES

Mix the OYA color formula with a whisk prior to application. For virgin applications, apply color to mid-lengths and ends prior to regrowth. When coloring 3 levels darker or more, advanced corrective color techniques such as pre-pigmenting may be required.

When covering medium hair:

Formulate one level lighter.

When covering resistant and/or coarse hair:

- Replace the gray covering series -0(N), -01(A), -04(B) in your mixture
with the -00(N+) series
- If your target shade is -01(A) or -04(B) mix equal parts target shade
with -00(N+) series
- If your target shade is -0(N), replace it with -00(N+) series formulate one level darker
- If no gray covering series are used in the formula, replace up to 50% of your fashion shade with the corresponding -00(N+) shade
