Blonde Hair Questions, Answered
Everything you need to know about the Treatments & Hair Masks collection before you shop.
Most hair masks should be used 1 to 2 times per week for blonde, bleached, or highlighted hair. Since chemically treated hair is more porous and prone to dryness, a weekly deep treatment helps rebuild moisture and strength that daily conditioner alone can't fully restore.
A hair mask is a more concentrated, longer-lasting treatment designed to penetrate deeper into the hair shaft, while regular conditioner provides lighter, everyday moisture and detangling. Hair masks are meant to be left on longer and used less frequently for more intensive repair.
A hair mask can significantly improve the look and feel of damaged or over-processed blonde hair by restoring moisture and strengthening the hair's internal structure, but it can't reverse chemical damage already done. Regular use helps prevent further breakage and keeps hair looking healthier between salon visits.
Most hair masks should be left on for 10 to 15 minutes to allow the treatment to fully penetrate the hair shaft. For extra dry or damaged blonde hair, some treatments can be left on longer or applied with heat (like a warm towel) for deeper conditioning.
Yes, a hair mask and hydrating conditioner serve different purposes and work best together. Conditioner provides daily maintenance moisture, while a hair mask delivers a more intensive, deeper treatment that targets damage and dryness a regular conditioner can't fully address on its own.
