What tends to shift
The differences you feel
Less puff when the air turns heavy
Smoothed hair tends to soak up less moisture from the air. Summer humidity is when the change is easiest to notice.
Shorter sessions with the dryer
Keratin Complex says NKST dramatically reduces blow-dry time, and smoothed hair often dries faster, so the round-brush routine can take a smaller bite out of your morning.
Softer to the touch, easier to detangle
A comb slides through wet hair with less tugging, and the ends tend to look neater in the weeks between trims.
Styles keep their shape
A sleek finish that once lifted and fuzzed by early afternoon has a much better chance of making it to dinner.
