Anyone with frizzy, rebellious, or humidity-reactive hair who regularly blow-dries or straightens; suitable for all hair types, including chemically straightened hair.

It's a leave-in product meant for everyday at-home styling - despite being part of L'Oreal's professional retail line, it doesn't require a stylist to apply.

Frizz control from a lightweight serum often washes out or wears off within a day, so this cream is formulated to hold its anti-frizz effect for up to four days according to L'Oreal, even as humidity climbs - useful for anyone who isn't blow-drying or straightening daily. The Pro-Keratin complex is designed to temporarily reinforce the hair's outer structure, while kukui and evening primrose oils add slip and a humidity barrier, which is why it's applied before drying rather than used as a rinse-out treatment.

• Shampoo hair as usual and towel-dry to remove excess water
• Apply the cream evenly through damp hair, focusing on mid-lengths and ends
• Do not rinse out
• Blow-dry and style as usual

Pros:

• Anti-frizz effect is designed to last several days rather than washing out after one styling session
• Leave-in formula doubles as heat-styling prep before blow-drying
• Suitable for straightened and other chemically treated hair

Cons:

• A full ingredient list isn't published by retailers, so buyers with specific ingredient sensitivities can't fully vet it before purchase
• As a leave-in cream, over-applying on fine hair can weigh it down
• Anti-frizz duration claims come from L'Oreal's own testing rather than independent verification
