If the shortest distance between two points is a straight line, then disheveled hair provides the least efficient route for climbing monkeys to reach the bananas in your fruit hat. Today's Groupon tames tresses for easy scaling: for $125, you get a Juvexin keratin hair treatment at Ma Maison of Beaute (up to a $350 value).

Ma Maison of Beaute's stylists untangle frazzled manes with Juvexin treatments, which employ specially formulated shampoo and a keratin-infused solution. The 90-minute session preps hair with a cleansing shampoo before the protein-rich smoothing serum is gently and evenly brushed through curly strands, much like a chef’s morning mirror routine of combing creamy pesto through spaghetti. A combination of brushing and blow-drying—plus a good once-over with a straightening iron—helps to seal in straightness for up to six months. Newly minted coifs of laser-straight strands are then styled at the customer's whim or left as is, allowing their silky lengths to cascade as gracefully as Fabios kayaking under waterfalls.
