Rainy season frizz and waves | hair care for humid days
When the rainy season arrives, the same complaints come all at once: hair set in the morning has frizzed out by the evening, waves are so pronounced that nothing stays in place, the scalp feels greasy. This article sets out the basics of hair care that holds up in humidity.

Why hair frizzes in the rainy season
Where damage has left hollows inside the hair, moisture from the air is taken up unevenly, the hair swells, and that is what produces waves and frizz. The key to hair that stands up to humidity, then, is to keep it filled with moisture and well conditioned so that it stays easier to manage.
Three steps against humidity
1. Intensive moisture care 2/3 times a week
A hair mask is an effective way to smooth damaged sections and settle the moisture balance. In ONSENSOU's Golden Silk Hair Mask, Beppu hot spring algae extract and silk ingredients add moisture and shine, leaving hair that stays in place.
2. Dry the hair properly
Letting hair dry on its own leaves the cuticle open and quick to take up moisture from the air. Direct the airflow from the roots towards the ends, then finish with cool air to close things down, and the shape holds for longer.
3. Build a barrier with a morning moisturising mist
Topping hair up with a moisturising mist such as ONSENSOU Gold Mist Hair & Body before you style makes it less susceptible to humidity from outside.

Dealing with a greasy scalp and odour in the rainy season
As the temperature and the humidity climb, sebum and sweat leave the scalp feeling greasy. Washing several times a day with a shampoo that cleanses too strongly, though, can unsettle sebum production instead. Washing carefully once a day with the amino-acid based ONSENSOU Scalp Care Shampoo is the better approach. Lifting dirt away gently and keeping the scalp clean helps prevent dryness and tightness and keeps odour in check. For those who want a brisker finish, the version with menthol is the popular choice.
Products matched to rainy season concerns are gathered together in the rainy season intensive care selection.
