Frequently asked questions
Can Cool Summer go blonde?
It depends on the type of blonde. Cool Summer can wear blonde shades that match their Cool pink-blue undertones. The key is choosing the right temperature — ash, platinum, or cool champagne tones rather than the opposite. Consult with a colorist who understands undertone theory.
How often should Cool Summer touch up color?
This depends on the technique. All-over color typically needs touch-ups every 4-6 weeks. Balayage and highlights can stretch to 8-12 weeks because the grow-out is more gradual. Glosses and toners fade after 6-8 washes, so budget for monthly refreshes if using these.
Will coloring my hair change my color season?
Your color season is based on your natural coloring — undertone, contrast, and intensity. While hair color can shift how some palettes look on you, it does not change your fundamental season. However, a dramatically different hair color may mean you borrow more from a neighboring subseason palette.
Should I match my hair color to my season palette?
Your hair color does not need to come directly from your season palette, but it should harmonize with your undertone. Think of it as the frame for your face — the frame should complement the picture, not compete with it. The shades recommended in this guide are chosen for that harmony.
