About

Extensions by Jen works from two Illinois locations. Gurnee is the primary location and is reached by phone or text. The Libertyville location is inside Zachary Chase Hair & Spa, with its own phone line. Gurnee is open Tuesday through Friday, and Libertyville is open Monday, Tuesday and Saturday, so the two studios cover different parts of the week.

The business describes itself as a trendsetter in eyelash extensions and says it has over 20 years of expertise. Eyelash extensions are the core of the business and come in three hand-crafted styles: classic, where one extension is placed on each natural lash; volume; and a mascara, wet or hybrid style that mixes volume and classic techniques.

Lash fill prices assume fills every two to three weeks. If a client goes past three weeks since the last fill, each additional week adds $25, and after six weeks a new full set may be needed. A booking fee holds the appointment and is applied toward the service. Cancellations made within 24 hours of an appointment and no-shows forfeit that fee and may be charged for the reserved time.

Beyond lashes, the business offers hair extensions that are blended to add length, volume and dimension and color-matched to the client's natural shade, along with a Keratin Complex smoothing treatment for frizz. Makeup artistry is available for everyday looks, special events, weddings and photoshoots. Waxing covers brows, face and body. Products are professional-grade and made to USA or UK standards, and the business recommends Xtreme Lashes mascara, eyeliner and lash cleanser for clients with extensions.

The business views regular lash and hair maintenance as part of self-care that supports confidence, and uses professional-grade products made to USA or UK standards.
