There are several cans of hairspray on Nomi’s dressing table: one is by Rayette, the other is the unscented, extra super-hold version of AquaNet.
There are several bottles on the bathroom shelf in Thomas’ studio.
The dark green bottle on the far left is the atomiser of Rochas Moustache eau de cologne. This fougère fragrance, created by Edmond Roudnitska, was launched in 1949.
Behind Moustache there’s a tall bottle with red stopper: it’s Eau de Quinine hair tonic by Pinaud.
The most intriguing bottle sits on the far right side of the shelf: it’s the one made of frosted glass and with gold stopper.
It’s Lenthéric Onyx cologne, launched in 1964 and now discontinued.
Dora (Margherita Buy) is taking a bath in Luigi’s bathroom. The three bottles behind her are Italian drugstore products.
The transparent bottles are both by Omia Laboratoires: one is the aloe vera body wash, the other is the tea tree oil shampoo.
The blue bottle is the Blue Iris foam bath by Perlier.
Colin (John Bradley) is sitting backstage while Kat is performing live. There are some interesting products on the dressing table in front of him.
The tall bottle with gold stopper is from the Global Therapy line by Franck Provost.
The aqua pump bottle next to it is Styling 3 wet-look gel by Franck Provost.
The elegant white jar contains Tatcha The Silk Cream.
Last, the black jar is another Franck Provost product – the Styling 2 modeling wax.
Kat is finally back home after her disaster concert. Jimmy Fallon is on tv and he’s making fun of her. There are some beauty products on the table in front of her tv.
The tall bottle with silver cap is Franck Provost Styling 3 normal-hold mousse.
The other two bottles with gold caps are from the Global Therapy line by Franck Provost.
Kat (Jennifer Lopez) takes a bath after her concert went terribly wrong.
Most of the products on the shelf by her bath tub are by Franck Provost.
The two black tubes on the left are from the Styling 3 line – strong-hold gel and curl-enhancer fluid.
The white tall bottle and jar with gold caps are from the Oleo Active line: they are Huile Sublime, a treatment for very dry hair, and the mask.
The black bottle with gold cap is the shampoo from the Global Therapy line.
Last, the white bottle on the right is another product from the Oleo Active line: it’s the shampoo for very dry hair.
Jodi (Ava Michelle) is sitting at a dressing table after performing as Kim McAfee in the musical Bye Bye Birdie.
There are several beauty products on the dressing table.
The tall brown bottle on the left is Hask Argan Oil repairing shampoo.
Right in front of Jodi there are two Noxzema products. The tube is the anti-blemish daily scrub, while the tall jar is the deep cleansing cream.
The pink tube with green cap is none other than Maybelline Great Lash mascara.
The black tube is Wet n Wild Mega Last matte lip colour.
When Jack (Griffin Gluck) joins Jodi backstage, we can see a couple more products.
There’s a can of TRESemmé Tres mousse.
Last but not least, two bottles of OPI nail polishes.
While Morvern (Samantha Morton) is taking a bath, we can see two interesting products on her tub. Both of them have been discontinued or have a different packaging now.
One is Timotei grapefruit hair conditioner (old packaging).
The other is Jurlique foaming facial conditioner.
TV preacher Tammy Faye (Jessica Chastain) has a very distinctive make-up and hairstyle, so it’s not surprising to see her dressing table packed with products.
The green lipstick tube is by Revlon from the Moon Drops line, first launched in the late 1950s. The lipstick collection, which included 20 shades, was launched in 1964.
The perfume on her vanity is Estee Lauder Private Collection, a green floral fragrance created by Vincent Marcello and launched in 1973.
In the background there’s a can of Aquanet all-purpose hairspray.
Thanks to Kelly in the comments for the Estee Lauder perfume id.
Olivia (Jennifer Aniston) is obsessed with Résolution D-Contraxol, a Lancôme anti-age treatment. She got several samples at different department stores but they’re not enough: when she sees a full-size jar of it in the bathroom of one of her clients (she’s a maid), she doesn’t think twice and takes it home.
In the bathroom there’s also Bumble & Bumble Prep conditioning spray.
She ends up using it lavishly as a foot cream! I guess it’s the magic that happens when you get a very expensive cream for free.
