Frizz Control in Humidity

Humidity exposes everything.

In tropical or coastal climates, hair oils need to do more than shine. They need to seal.

Ouai in humidity

• Smooths initially

• Works beautifully indoors

• Can fade faster in high moisture air

Gisou in humidity

• Creates a slightly stronger barrier

• Helps control frizz longer

• Better for textured, color-treated, or porous hair

If you’re stepping into real humidity, Gisou holds up better.

Ingredients Breakdown

Ouai Hair Oil

• Silicone-based smoothing agents

• Lightweight botanical oils

• Designed for gloss and manageability

Silicones help with instant smoothness but may not deeply treat dryness.

Gisou Honey Infused Hair Oil

• Honey as a key ingredient

• Rich botanical oils

• Focused on repair and moisture retention

Honey is a humectant, meaning it attracts and holds moisture. That can be beneficial when balanced properly in a formula.

If your hair is damaged or bleached, Gisou offers more long-term nourishment.
