Jenny Jackson is a Vice President and Executive Editor at Alfred A. Knopf. A graduate of Williams College and the Columbia Publishing Course, Jenny lives in Brooklyn Heights with her family. Her first novel, Pineapple Street, was a New York Times bestseller. The Shampoo Effect is her second novel.

I devoured The Shampoo Effect. Jackson has a rare knack for capturing the intensity of old friendships and the way love, jealousy, money, and history combust until everyone is behaving (deliciously) badly. It's funny, drama-fueled, and full of Jackson's breezy wit, but what stayed with me most was how honestly and insightfully it captures the grit beneath the gloss of these characters. A brilliant story of marriage, motherhood, and the difficult work of breaking old patterns to become someone new
