The short answer
Best Overall AlternativeSilicone-rich blend for frizz control · $7.97 · 97.6 ml
Best for FrizzFeatherlight silicone finish for fine hair · $58.00 · 59.1 ml
#1
Best Overall Alternative
- Size: 97.6 ml
- Price per ml: $0.08/ml (original $0.05/ml)
The why
A silicone-heavy oil blend with coconut oil works best on mids and ends as a pre-wash, often left for 20–30 minutes. Fine-haired users like the shine and frizz control, but overapplication can leave stringy grease behind.
One minus
Overapplication can leave stringy, greasy hair
Both recommended for Frizz.
“It tames my frizz without giving my hair that plasticy, drenched-in-oil look.”

The original, at a glance

- Silicone-based smoothing that beats oils for frizz control
- Price
- $6.97 · 150.8 ml · $0.05/ml
#2
Best for Frizz
- Size: 59.1 ml
- Price per ml: $0.98/ml (original $0.05/ml)
The why
A silicone-rich bonding oil for smoothing frizz, adding shine, and protecting ends during heat styling. Fine-haired users love the weightless finish, but fragrance, buildup, and occasional scalp reactions make it a poor match for sensitive scalps.
One minus
Too much turns fine hair greasy or stringy
Both recommended for Frizz; discussed alongside Garnier Fructis Sleek & Shine Anti-Frizz Serum in 8 threads.
“Have you tried the Olaplex oil ? My hair is very frizzy but if I put it on dry it really tames it”
