I love when my hair is blonde but I think I'm too critical about my hair when it's blonde. Whenever I go blonde it's always by highlights (i'm not into the blonde one process).

Here's my dilema and I'm hoping you ladies can help me. Each time I get blonde highlights I feel like you can see 'old' blonde highlights and they're grown out. How do you avoid this without a one process?

I'm naturally light brown and I go for the champagne/beige color highlights.
