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
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
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
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
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
In this juicy send-up of privilege in all its rowdy dysfunction, a writing fellowship brings nepo baby Caroline Lash to small-town New England. There, she falls for a local environmentalist with a cliquey friend group that will soon regret freezing her out.
People
Jackson paints a nuanced, empathetic, distinct picture of each woman, exploring different views on marriage, parenthood, career aspirations, and adulthood... This astutely observed story is funny and gossipy without veering into the mean-spirited. Hand this to readers who love Emma Straub, Amy Poeppel, and Katherine Heiny.
Booklist (starred review)
Jackson rotates the point of view around the set of friends, deftly depicting the practices and pressures of modern parents... This easy read combines a literary rom-com with an acute portrait of midlife among millennials.
Kirkus
A frothy, exuberant book.
Vogue
A fantastic character-driven read.
Shelf Awareness
Meant to be read on a sweltering July day, with sand between your toes. Like Jackson's popular debut, Pineapple Street, this is one of those rare books that feel both breezy and meaty, sharp but empathetic.
Toronto Star
The Shampoo Effect is a stylish, sharply observed novel about image, reinvention, and the chaos simmering beneath polished lives. It's perfect for readers who love emotionally messy characters with great taste...
The Sunday Series
Jackson has a knack for local color and well-rounded character work... this has plenty of heart.
Publishers Weekly
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.
