Rained all day. Zero frizz. Two coworkers asked if I'd just come from the salon.

Baby-fine hair that everything weighs down. This is the first serum that doesn't.
J
✓ Verified Buyer
Cancelled my $320 keratin. Same glass-smooth, fraction of the price.
P
✓ Verified Buyer
Other serums quit the second I went outside. This lasts 3 days — in Florida.
H

Two pumps and it feels like silk again. My husband asked what changed.

Flat-ironed once and it stayed smooth 3 days — through two gym sessions.

Why it smooths without the grease
Every other serum COATS your hair. That's the problem.
Coating is why serums go greasy, build up, dull by Friday and quit by lunch. QT-Charge absorbs into the strand instead of sitting on it.

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. Silicones coat and build up; QT-Charge bonds the cuticle itself, then washes clean. No buildup, no film.

Your old serum quit by lunch and dulled by Friday. This absorbs, then washes clean — no buildup.

Straight talk
The unflattering bit, so you can trust the rest.
Straight talk: what this serum is NOT
+
This is a finishing serum, not a deep conditioner. It seals frizz and smooths the cuticle — it won't rebuild severely damaged hair, and it won't replace a mask for very dry, coily hair. If that's what you need, this isn't it.
Still on the fence?
Quick answers before you go glass-smooth.
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?
+
Smoother and shinier the same day. Fuller results build over 2–4 weeks with consistent use.
Do I need a blow dryer or heat?
+
No. Works even if you air-dry — one pump, no heat needed.
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.
