Curly Me Official Website to Reopen in Late June 2026: Rain Season Hair Care Expert Tips

The rainy season has arrived in earnest, a period when those with curly hair often face greater challenges than usual due to frizz and expansion caused by humidity. Many people likely feel they waste their time meticulously blow-drying only to have their hair return to its natural state within five minutes of stepping outside. It is said that approximately 60% to 70% of Japanese people have some degree of curly hair tendency.

Curly Me Co., Ltd. is set to reopen its official online shop, "Curly Me Official Site," in late June 2026. The site is an official outlet for hair care products for curly hair, supervised by the owner and hair diagnostic specialist, Curly Girl Rin. Rin, having struggled with her own curly hair, has been sharing information on how to embrace curly hair in line with Japan's climate, drawing from the U.S.-developed "Curly Girl Method."

In addition to product sales, the site features content on hair care and styling tips. Ahead of the renewal, they are introducing "techniques to solve curly hair troubles during the rainy season," and the new site will host an abundance of such helpful content.

■ Why does hair wave during the rainy season? The mechanism of "hydrogen bonds"
When you blow-dry hair while straightening it, the proteins bond together via hydrogen bonds, maintaining a straight shape. However, when humidity is added and the hair gets wet, these bonds loosen. If hair dries while loose, the original curl reappears.

To maintain a beautiful hairstyle during the humid rainy season, it is recommended to "embrace your curls" rather than forcing them straight with a blow dryer. During the rainy season, you should incorporate styling agents that enhance your natural waves or curls.

■ The mechanism of "frizz" and expansion
There is a reason why curly hair tends to expand during the rainy season. Curly hair is prone to dryness and tends to absorb moisture from the air in high-humidity environments. This causes the inside of the hair to expand and the cuticle to open easily. Furthermore, because curly hair has an uneven internal structure, moisture absorption is also uneven, leading each strand to swell disproportionately. As a result, the frizz and expansion become more intense, making the entire hair look voluminous.

■ The "LOG Method" to overcome the rainy season
The "LOG Method" proposed by Curly Girl Rin is a three-step process to prevent humidity-induced expansion while maintaining curls.

L (Milk/Cream): First, apply a leave-in treatment to wet hair to moisturize it (Liquid & Leave-In).
O (Oil): Layer a small amount of oil on top to coat the surface with oil and prevent excessive moisture absorption.
G (Gel): Finally, set the hair with gel to keep the curls. This suppresses humidity-induced expansion and maintains the texture of the curls.
