Iron sprays get judged on one number, and this one covers heat to 230C. That is the top of what a domestic straightener will do, so the protection is real rather than nominal.

The frizz claim is the more interesting part. L'Oréal put three days on it, which means the spray is doing more than protecting during the styling. It holds the smoothness afterwards, through the nights and the humidity in between. Genamine-si is the technology they credit for it.

It is a leave-in, sprayed on before the iron goes near the hair, and it is aimed at long, dry, damaged or frizzy lengths. That combination is common. Hair below the shoulders is old hair, it has been ironed before, and it frizzes at the ends first.

Best for anyone straightening long hair regularly. Fine, short hair will find it more product than the situation needs.

Application tips

Spray it on dry hair before an iron, not on wet hair, which is what people get wrong with an iron spray.

Section the hair and mist each one lightly from about six inches back, front and back of the section. Comb through so it is not sitting in wet patches. Let it dry for a few seconds, then take the iron through. A light pass on the second day tidies things up without needing a rewash.

Results

Hair goes under an iron with something between it and the plates, which over a year of daily straightening is the difference between ends that survive and ends that do not.

Smoothness lasts well past the day it was styled, so a Tuesday blow-dry still looks deliberate on Thursday. Frizz stays flat through damp weather, and hair keeps a light, sprayed-not-coated feel rather than going stiff or tacky the way older heat sprays did.
