When Big Kurt Jackson and Chavo barge into the girls' dressing room to complain about Carmen's moves (stolen from her brothers), Debbie (Betty Gilpin) acts as peacemaker. In the screencap above, Tammé (Kia Stevens) is holding a can of Aqua Net hairspray; on the glass shelf by the washbasin there's Maybelline Great Lash mascara.
After being featured several times in S01, the super-hold version of Aqua Net hairspray gets namechecked. This happens during a match between Melrose (Jackie Tohn) and the Beatdown Biddies: Melanie uses it a weapon.
Melrose (Jackie Tohn) is the protagonist of the video Makeover, which features most of the G.L.O.W. girls, too. On her vanity table there's a bottle of Oil of Olay. There's also a can of Aqua Net hairspray.
There are many perfumes on Debbie's dresser, but one of them has caught my attention. It may be filled with turquoise liquid, but the bottle with gold and dark blue is definitely by Boucheron. It's the 100 ml splash eau de toilette version. Picture source.
