This type of frizz occurs when hair is medium to high porosity and absorbs moisture from the air, causing individual hairs to swell and the cuticle to lift.
A final rinse with cold water is a good general preventative for this type of frizz and can be aided with a conditioner, such as
Featherweight™ or
Intense Quench™, that lowers pH to the optimal level between 4 and 5. Just as a higher (more basic) pH opens the cuticle and makes hair feel rough, a lower pH will seal it up and make it feel smooth.
The most important tool in your frizz fighting arsenal is an anti-humectant (or moisture-repelling) definer that coats the hair and keeps the cuticle from lifting.
Hold Up™,
Mane Tame™ and
Just Gel™, do just that by forming a light film that keeps unwanted moisture from penetrating the hair.
