Hair is like a mechanical bull ride: if you can make it look smooth, you won’t feel so embarrassed that you have to hide your head beneath a giant cowboy hat. Corral a smooth style with today’s Groupon: for $129, you get a Cashmere Luminance Japanese hair-smoothing treatment at Tomoko Shima Hair Salon (a $350 value).

The seasoned stylists at Tomoko Shima Hair Salon perform Milbon’s Cashmere Luminance smooth-control treatment in order to soften and straighten locks for up to three months. Safe and gentle, the service employs a formula made with silk-protein extracts and moisturizing lanolin, but not a drop of formaldehyde. The treatment typically takes about two hours, allowing guests to rehearse their line-for-line claymation remakes of Casablanca with their hairdressers. Strands emerge with a shiny, lightweight finish that can undergo additional volume or color treatments immediately. Following the treatment, clients can blow-dry their way to a sleek look instead of grilling tresses in a panini press. The service is only recommended for clients with highlighted, colored, or damaged hair.

Soft styling chairs imported from Japan host clients during the mane-taming service. The coiffing crew launders locks with authentic Japanese shampoos including Milbon’s Crede and Nigelle, and they pamper scalps with showerheads that remove chlorine from the water. Clients can take in the salon’s peach-and-mandarin-orange color scheme to boost their moods or lick the walls to sate their cravings for fruit salad.
