A sleek new ’do adds style while removing stubborn cowlicks and rogue hook and loop sneakers trapped in your hair. Reshape your look with today’s Groupon: for $135, you get a keratin hair-smoothing treatment at Elena Echeverry Hairdressing (up to a $350 value).

Elena Echeverry calms up to 95% of follicle frizz with high-gloss Keratin Complex smoothing formula and more than 20 years of cosmetology experience. The two–three-hour treatments begin with a clarifying shampoo and a light toweling that readies all hair types to receive the gentle straightening serum. A shower cap keeps in heat to help the keratin proteins penetrate cuticles to block the effects of humidity, promote healing of damaged locks, and craft unbreakable passwords to lock out crafty environmental toxins. Echeverry then dries the product with warm breezes from a vent brush and presses remaining kinks into straight, burnished strands with a high-temperature iron. At home, previously unmanageable manes submit to the blow-drier faster and retain a silky lustre for three–five months, particularly if washed and conditioned with lathers free of sodium-chloride or scissors.
