This dark blonde look by celebrity colorist Isabelle McGuire (@isabelle_bomane) at Bomane Salon is all about refining what’s already there. Instead of adding more blonde, Isabelle enhanced her client’s natural base with Redken Shades EQ™."This is what a lot of blondes think is their 'dishwater' natural color, but when it’s all grown out, it’s the perfect dark blonde," Isabelle says. She used LINEONE Hair Keratin Tip Wavy Extensions to add dimension and length while keeping the color cohesive and low contrast.

The Formulas

Formula A (roots)
Redken Shades EQ™ 9N + Redken Shades EQ Processing Solution

Steps

  1. Apply Formula A all over on towel-dried, damp hair. Fully saturate from roots through ends and process for 20 minutes to refine tone and boost shine.

    “This is what a lot of blondes think is their ‘dishwater’ natural color,” Isabelle says. “But when it’s fully grown out and glossed, it’s such a gorgeous dark blonde.”

  2. Add LINEONE Hair Keratin Tip Wavy Extensions 20 Rooted Dark Golden Blonde and Keratin Tip Wavy Extensions 26 Rooted Neutral Blonde. Isabelle places the darker 20 pieces through the front because it “keeps it from looking stripy on her darker blonde,” helping the blend stay soft and natural against the client’s base.

  3. Keep heat styling minimal to maintain hair health and longevity. The wavy extension texture helps preserve movement without relying on daily heat.

Maintenance and At-Home Care

Isabelle recommends minimizing heat at home to preserve hair health, noting that this shift is one reason many clients are moving away from frequent highlighting. The wavy extension texture helps maintain movement without relying on daily heat styling.

  • Refresh the gloss every six to eight weeks
  • Remove and replace extensions every 12 weeks

For at-home care, Isabelle recommends:

  • LINEONE Extension Shampoo
  • LINEONE Repairing Conditioner
  • LINEONE Weightless Detangler 
  • LINEONE Remedy Oil

She also recommends the Ibiza Hair CX8 Brush to maintain softness and shine between appointments.
