Among the latter is a quietly successful brand and product you may be sleeping on: the Serge Normant Dream Big Instant Volumizing Spray. Over the last few years, I went from having rarely ever heard of the Dream Big spray to watching it pop up in the beauty routines of the rich and the famous — first Sarah Jessica Parker, then Meghan Markle, and now Brooke Shields. Last week, Shields made an appearance on Watch What Happens Live with Andy Cohen; whether or not you tuned into this specific episode, you should tune into the lustrous, shiny, and perfectly coiffed hairstyle the model donned for her moment in the hot seat. In a pre-show, backstage photo posted on Instagram stories, Shields' hairstylist Tim Nolan can be seen spritzing Dream Big all over her hair while someone else applies what seems to be body lotion. The end result was a gleaming Shields, who had a pristine complexion and perfectly voluminous hair to match. SJP once told People that the spray is a "must," before adding, "It works for so many people. Use it instead of dry shampoo or hairspray to give your hair more body." And last year, when Markle and Prince Harry graced the cover of Time's Most Influential People issue, the duchess' hairstylist was none other than Serge Normant — celebrity stylist and creator of the line — who used the iconic blue bottle to achieve her cascading hair. Courtesy Shop now: $25; amazon.com Beyond its credits as a go-to for glamorous celebrity hair, the Dream Big spray also has hundreds of five-star ratings on Amazon — and lucky for us, a drugstore price tag at just $25 a bottle. The mineral- and protein-packed formula goes on transparent, so you won't be left with a chalky residue or baby powder-looking finish, while providing a subtle lift and a flexible hold on all hair types. A number of reviewers with thin hair have attested that it really works, including one person who wrote, "I have fine, thin hair so imagine my surprise when a spray gave me a huge head of hair." Another user echoed this sentiment and said the product is "lightweight, not sticky, and gives my very fine hair lots of volume." Head to Amazon to try the celebrity stylist-approved lifting spray that will add incredible body to your blowout for just $25.
