From 74 Reddit threads · Updated November 3, 2026
Lightweight silicone oil smooths frizz and shields hair from heat; pricey. The catch: pricey compared with cheaper oils. Here's what Redditors reach for instead.
The short answer
Best Cheaper AlternativeSilky finish without an oily afterfeel · $25.00 · 71 ml vs $58.00 for the original
#1
Best Overall Alternative
- Size: 59.1 ml
- Price per ml: $0.32/ml (original $0.98/ml)
The why
A silicone-heavy finishing oil with argan oil, moringa oil, and hydrolyzed soy protein, designed for smoothing dry ends and breaking gel casts. Fine-to-medium wavy hair gets frizz control, though overapplication can flatten it and fragrance may bother sensitive noses.
Both recommended for Frizz.
“It's really light and doesn't add much volume, but it helps define wave patterns and wards off frizz.”
