New clients start by filling out an online consultation form, which the salon reviews before texting the client back. Visits are by appointment only. Installation methods include wefts, tapes, keratin bonds, and K tips, and services range from as short as 30 minutes to as long as 3 hours. Maintenance visits usually fall every 6 to 12 weeks, depending on the installation method.
Installs are priced from $300 to $3,000, depending on method, fullness, and length. Installs that add both fullness and length average $1,200 to $1,600 as an initial investment. Membership prices do not include the cost of hair. The salon states that its pricing has no confusion, pressure, or surprises.
