This is wavy hair on day one with a hair gel containing Polyquaternium-4.
|Day one with polyquaternium-containing gel.|
The same product was used again for the photo below, probably just rinsing the hair in between.
But the second use revealed the ugly side of polyquaterniums. Everything was done the same as the day before. But the result was quite different. Stringy, crunchy, less volume, dull, less wave definition, kind of sparse and a little frizzy.

So now you know. If this happens to you and your hair gel (or shampoo or conditioner or mousse or styling cream) contains polyquaterniums, you might want to avoid them and see if your hair behaves more nicely.
It doesn't always happen on the first or second use, this is a cumulative process. They all build up for me right away. No sleuthing necessary.
