Revlon Professional's Lotus Flower Hair Treatment (also known as UniqOne) is a leave-in spray treatment applied to wet or dry hair and never rinsed out. It combines UV filters, silk amino acids and conditioning agents for a multi-benefit formula Revlon markets as covering ten different benefits, including detangling, frizz control and added shine.
Revlon Professional positions this as a pro-channel product for salons and their clients, though in practice it's also widely available at general retail — it isn't strictly salon-exclusive despite the "Professional" branding. Spray amount scales with hair length, from a couple of sprays for short hair up to around fifteen for long hair, based on Revlon's own directions.
It doesn't carry a specific heat-protection temperature claim, so while heat protection is one of its stated benefits, we can't confirm a number to back it up.
