The science · QT-Charge technology

Frizz isn't permanent damage. It's hair that lost its charge.

Salons smooth what $60 oils only coat — here is the difference, and why one pump does it with no heat.

Frizzy · damagedSealed · glass-smooth
1

Damage strips your hair's charge

Heat, brushing and humidity leave the cuticle negatively charged — that's frizz, static, split ends and tangles.

2

QT-Charge actives are positively charged

Omega 3·6·9 and polypeptides carry the opposite charge. Opposites attract — so they're pulled straight to your most damaged spots.

3

They seal where it matters

Locked in place, they smooth the cuticle and reinforce your hair's own keratin — silky, shiny, frizz-locked. One pump, no heat.

Glass-smooth, frizz-locked — no straightener, no $60 bottle.

Still on the fence?

Quick answers before you go glass-smooth.

*Based on laboratory testing, consumer-use studies, user surveys, verified reviews and internal sales data. Individual results vary.

What hair types does this work on? +

All of them — curly, wavy, straight, fine, color-treated. It works with your texture.

How fast will I see results? +

First use. Smoother, shinier, frizz-free the same day.

Will it make my hair greasy or heavy? +

No. Weightless. One pump feels like nothing.

Isn't this just silicones? +

No. Silicones coat and build up — that's why your old serum quit by lunch and dulled by Friday. QT Charge bonds the cuticle itself, then washes clean. No buildup, no film.

How fast is shipping? +

Orders ship within 24 hours with free tracked shipping. Most arrive in 3–5 days.

What is your return policy? +

60-day money-back guarantee. Not glass-smooth? Full refund — no questions asked.
