Critics Review

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 – Coco Mellors, New York Times bestselling author of BLUE SISTERS
I 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. – CATHERINE NEWMAN, author of WE ALL WANT IMPOSSIBLE THINGS
An 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. – Elin Hilderbrand, #1 New York Times bestselling author of SWAN SONG
Funny, sharp, and charming – Rebecca Serle, New York Times bestselling author of ONE ITALIAN SUMMER
The 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 – Belle Burden, #1 New York Times bestselling author of STRANGERS
One of the smartest, funniest, and most astute novels I’ve ever read … presented by Jenny Jackson with a combination of great humour and profound wistfulness. I loved this novel. You will, too. – Chris Bohjalian, author of THE FLIGHT ATTENDANT and THE AMATEUR
Warm, witty, sharp and clever – it’s the perfect smart summer book. Absolutely delicious! * Daisy Buchanan, author of CAREERING *
Smart, funny, and perceptive, Jenny Jackson captures the messiness of modern relationships with rare precision. THE SHAMPOO EFFECT is an addictive, beautifully observed read. – Louise O’Neill, author of ASKING FOR IT
A smart, sly gloss on Updike’s tales of marital unrest. So funny, so compelling, this novel hit home with me in its examination of the ways secrets can erode families and friendships. – Joanna Rakoff, international bestselling author of MY SALINGER YEAR
The platonic ideal of a beach read: fun and fast-paced, with a cover that screams, “Can I borrow your sunscreen?” It also features one of my favourite setups (dating back to “Up Island,” by Anne Rivers Siddons), in which an outsider arrives in a clubby enclave and makes waves. … Here, [Jackson] delivers us to the land of clam rolls with [an] anthropological eye. * New York Times *
