Keep your classic eyelash extensions looking clean, balanced, and naturally defined with a Classic Lash Refill at Lash & Glow Studio in Old Town Scottsdale. Grown-out extensions are carefully removed, and new individual extensions are applied to restore the soft, natural 1:1 look. Refills are recommended every 2 weeks and must be completed within a maximum of 3 weeks. If too few extensions remain, a new full set may be required.
