Meet Your Educators

Drea Henty

Andrea Henty is a hair extensionist, colorist and stylist always seeking to create the most wake-up-and-go, easily maintained look for her clients.

With over a decade of experience as a celebrity hairdresser, Andrea, along with her partner Sonny, opened BOMANE Salon in Beverly Hills, California seven years ago.

In that time, BOMANE has quickly become one of the top luxury hair salons in Beverly Hills, specializing in hair extension services.

Andrea founded LINEONE Hair in 2020, seeking to solve the issues she found when using other hair lines. LINEONE was created by a hairdresser, for hairdressers- focusing on true to life colors, master education, and essential tools.

LORIEN MEILLON

Lorien is a seasoned professional in the hair industry with over 17 years of experience, specializing in transforming client looks through hair extensions.

Her diverse expertise spans from behind the salon chair to editorial projects and television appearances.

After several successful years in Los Angeles, where she honed her skills alongside Andrea Henty, the founder of LINEHAIR, Lorien followed her heart and relocated to Nashville, TN.

This move ignited her desire to empower fellow stylists, sharing invaluable insights on how to grow and pivot their extensions business, even amidst a cross-country transition.

ISABELLE MCGUIRE

Isabelle is an individual keratin extension specialist, educator with Line One Hair, and bi-coastal stylist based in Beverly Hills, California.

Working under Line One Hair founder Andrea Henty, Isabelle has mastered her skills in seamless hair extension applications.

Since becoming a hair extension specialist, Isabelle has traveled across the country training stylists in the art of extension applications and business building with Line One Hair.

Hair extensions have played a pivotal role in helping Isabelle scale her business and achieve career goals, and she is passionate about empowering other stylists to do the same.

ILSA LAMBERTI

Ilsa is a hair extension specialist from San Diego, California with over eight years of experience.

She discovered her passion for weft extensions about six years ago, and was drawn to their ability to transform hair by adding seamless volume and length. Extensions are a game-changer for clients, offering a natural look while enhancing their confidence and overall style.

Education has always been an important part of Ilsa’s career, and she’s grateful for the opportunity to now teach other stylists how to expand their skills and grow their business with extensions. Seeing the impact extensions have—both in elevating a stylist’s craft and giving clients hair they truly love—is what continues to inspire her every day!
