Coco Mellors, New York Times bestselling author of BLUE SISTERSI 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
Woman and HomeA gorgeous story
Catherine Newman, author of WE ALL WANT IMPOSSIBLE THINGSI binged The Shampoo Effect and am now bereft and also jealous. Jenny Jackson has written a book that's so breezily readable and laugh-out-loud funny while excavating the deepest truths about motherhood, family, and forgiveness. What an unforgettable cast of characters. What an accomplishment.
Elin Hilderbrand, #1 New York Times bestselling author of SWAN SONGAn absolute DELIGHT. This book has everything I love in a beach read: a coastal setting, multiple points of view, compelling storylines, and a delicious specificity to the writing that makes every single sentence feel fresh and alive. Jenny Jackson’s The Shampoo Effect is a must, must, must for your summer reading list.
Rebecca Serle, New York Times bestselling author of ONE ITALIAN SUMMERFunny, sharp, and charming
Belle Burden, #1 New York Times bestselling author of STRANGERSThe Shampoo Effect is a delicious, unputdownable portrait of a group of friends navigating love, marriage, and young parenthood. Jackson's characters are fully drawn, complex and flawed, each traveling a true arc of growth, arriving in the final pages at a deeper understanding of the ties that bind them to one another. I loved it
