Treat breeze detectors right with today’s Groupon: for $45, you get a custom relaxer (a $65 value), deep-conditioning treatment (a $10 value), and trim and style (a $10 value) at Ultimate Hair Secrets (an $85 total value).

An author and adroit cosmetologist with 25 years of experience, Donna Angelety operates Ultimate Hair Secrets, where she leads the battle against damaged hair. Each appointment begins with a consultation, during which clients can share thoughts and detailed flow charts about their coiffed futures. A deep-conditioning treatment rejuvenates strands from surface to root, and the Affirm FiberGuard relaxer system, of which Donna is a certified stylist, spatially configures shocks to be straighter and less stressed out during tense family dinners. Finally, a quick trim and style lend the healthier locks a trendier ’do.
