Brett (Igby Rigney) is checking his hairstyle during a break from Dance Off!, the dancing competition he’s taking part in.
Right in front of him there’s a spray can of Aquanet unscented super-hold hairspray.
Terry Schaffer (Wes Bentley), Debbie’s father, is acting like a helicopter parent: he’s doing everything he can in his power to make his daughter win the competition. In this specific scene, he’s talking about Brett’s Less Than Zero script, and arranges a meeting with the boy at the Beverly Hills Hotel.
On the far right side of the dressing table we can see a bottle of Rave unscented ultra-hold hairspray.
More products can be seen when he sits down.
There’s a jar of Vaseline pure petroleum jelly (Terry applies it on his lips).
The Mondrian-inspired can is from the Studio Line hair styling collection by L’Oreal, one of my most vivid memories from the 1980s (I loved the mousse and the gel).
The white bottle is Aquanet unscented super-hold hairspray.
Bash Howard (Chris Lowell), heir to the Howard Foods business empire and producer of GLOW, is one of my favourite characters of the show, so a scene set in his bathroom was very much welcomed by yours truly, who couldn’t wait to take a look at his beauty products.
First on the left of the marble top, there’s a bottle of Ralph Lauren Polo, the aromatic fragrance created in 1978 by Carlos Benaim. No surprises here: Bash is a flamboyant ring announcer and commentator, but he’s very conservative when it comes to appearances. A relatively traditional eau de toilette like Polo suits his character.
His hairstyle is very distinctive and trendy, so it’s obvious there are lots of styling products. There are two bottles of Vitalis hair tonic and an array of L’Oreal Studio Line items (hairspray, two mousses and gel). The choice of using Studio Line is excellent: this hairstyling line was very popular in the 1980s! I liked using
