Owner and stylist Terry Boschert oversees Shear-Lock Combs West’s team of salon and spa specialists as they pamper patrons with an array of exterior-enhancing services. The CHI Enviro smoothing treatment tames up to 95% of head frizz as stylists glide a heated ceramic piece over strands, sealing in a combination of amino acids, proteins, silk, and pearl. The infusion leaves hair in a cooperative, curl-free state for up to four months. Stylists will also supply clients with after-care products to help maintain smoothness.

After mane-smoothening sessions, head threads undergo a precision shearing, followed by an expert styling to complement facial features. Guests can then peruse haircare products and accessories, including shampoos and styling products ($5+), or the Chi Enviro Support Trio ($45), which can help sustain smoothness at home or when vacationing on the International Space Station.
