MEET kostas
Founder Konstantinos (Kostas) Vasilakis brings over a decade of experience in high-end salons and hairstyling education. Trained in Greece and the Netherlands, he’s passionate about precision cutting, advanced coloring, and working with all hair types—especially wavy and curly hair. At Studio Kostas, you’ll receive expert style, care and product advice and a personalized approach to achieve your perfect look.
ECO-FRIENDLY
Great hair shouldn’t come at the planet’s expense. That’s why we use vegan, cruelty-free products from brands like Maria Nila, Olaplex, Original Mineral, and Bouclème. Our eco-conscious approach extends to our salon design, from recycled capes to plant-based materials. We’re also proud to be recognized by Vegan Friendly for our commitment to sustainability. With CLIC Recycle we partnered to repurpose human hair into sustainable solutions for industries like regenerative agriculture and oil spill cleanups. We continuously seek new ways to reduce waste, ensuring every part of our process supports a greener future.
“Wonderful experience at Studio Kostas. The products were lovely and very natural, if you care about sustainability this is the right choice. The service was super friendly and professional.”
our SERVICES
Our tailored haircuts are designed to suit your hair texture and type, ensuring you leave with a style that works best for you. From simple trims to complete transformations, we focus on delivering a cut that looks great and feels right for your lifestyle. Along with your cut, we provide personalized product advice to maintain your style and promote healthy hair.
Coloring is an art, and our expert colorists are here to bring your vision to life. Whether you’re interested in balayage, highlights, or a full color change, we use high-quality, vegan, cruelty-free products that nourish your hair. During consultations, we discuss your color goals and offer advice to maintain your color, ensuring your hair stays healthy and vibrant.
To complement our haircuts and coloring, we offer nourishing treatments like Olaplex and specialized scalp care to repair, strengthen, and hydrate your hair.

At Studio Kostas, we strive to offer a smooth and respectful experience for all our valued clients. When you schedule an appointment with us, we kindly ask you to review the following terms:
You can cancel your appointment free of charge up to 24 hours before your scheduled time. Cancellations within 24 hours will incur the full service charge, either via invoice or by retaining your pre-payment. If you need to reschedule, it’s free within 4 weeks, subject to availability, except for no-shows.
We maintain a zero-tolerance policy for no-shows. Missed appointments without prior notice will be charged the full service cost, or non-refundable for pre-paid appointments. This ensures we respect all clients and stylists, preventing unnecessary wait times.
Your satisfaction is our priority. Let us know if adjustments are needed during your appointment, and we’ll gladly make any necessary touch-ups right away.
