OSL Hair is a premium hair extension brand born from Oaselle Salon - a luxury hair destination in Los Angeles, California, founded by extension specialists Katerina Grishanina and Nicole Frances.
Built behind the chair, OSL Hair is grounded in real-world extension expertise: years of daily installs, firsthand client feedback, and an uncompromising understanding of what modern luxury hair should actually look and feel like.
OSL Hair was created by salon owners and hairstylists who know hair—not just how it looks, but how it wears, how it moves, and how it makes you feel.
Born behind the chair and refined through years of working with high-level clients, OSL Hair was developed to deliver a truly luxury extension experience for both the stylist and the client. Every detail matters—from the sourcing to the texture, from the longevity to the final result in the mirror.
We specialize in premium Slavic hair, chosen for its softness, natural density, and unmatched blendability. This is hair that feels effortless, looks elevated, and wears beautifully over time. Lightweight, silky, and refined, OSL Hair is designed to become an extension of you—not something you’re constantly aware you’re wearing.
Our mission is simple: to provide elite-quality hair extensions that meet the standards of modern luxury salons. Hair that performs at the highest level, photographs flawlessly, and maintains its integrity with proper care.
OSL Hair is for those who expect more—more quality, more intention, and more confidence in every strand.
This isn’t just hair.
It’s a luxury experience.
