Barrington Hair Extensions

Barrington Hair Extensions is a boutique hair extension business based in Deer Park, Illinois, serving clients across Chicagoland, including Barrington, Chicago, and the North Shore. Led by Diana Carlini, who has nearly two decades of professional experience, the business specializes exclusively in luxury K-Tip, or keratin bond, extensions. Each installation is customized with careful color mapping, placement, and density planning to create natural-looking length and fullness while prioritizing the health of the client’s own hair.

Services include K-Tip extensions, extension correction and repair, color matching and blending, and personalized options for fine, thinning, or changing hair. Correction work may address weight distribution, bond replacement, blending, and shape. The business uses premium European hair described as ethically sourced from individual donors. New clients begin with an online assessment and receive tailored recommendations, an estimated investment, and guidance on maintenance and suitability. Barrington Hair Extensions also provides aftercare information, a K-Tip care guide, recommended products, and custom clip-ins.
