What is JCOS?

JCOS stands for Japanese Cosmetics, and we’re obsessed with Japanese beauty. Born from a desire to share the simplistic and ritualistic traditions Japanese women have practiced for centuries with women everywhere is what JCOS is all about. Intertwining an all-inclusive “by-women-for-women” philosophy with the uniquely Japanese perspective that a life of cleanliness and simplicity, focusing on a balance of inner and outer well-being, creates a harmonious relationship between the senses and the soul. The JCOS line of purposeful and innovative lifestyle products was created to introduce Asian beauty culture to women across the globe, regardless of age, race, or ethnicity. Eco-conscious to the core, JCOS products are made with responsibly sourced natural resources, and never tested on animals. Designed to rejoice in the beauty of the moment, while keeping an eye on future generations, our products are made from organic and sustainable materials, reflecting our core beliefs and deep respect for the planet.

What makes Japanese hair products different from Korean hair products?

Korean products focus on answering immediate hair concerns and offer wow effects, whereas the Japanese philosophy is based on prevention and sustained results.

Korean beauty follows the hottest trends of the moment, while Japanese beauty has its roots in long-lasting and proven rituals and traditions.

Korean beauty embraces a faster pace, while Japanese beauty focuses on a slower-paced way of life, believing that breathing, contemplating,  and mindfulness should be embraced.

I’m an American caucasian woman. Can I use your products on my hair?


Our products were originally created for Asian hair types, but our universal formulas work for all hair types, including color-treated hair.

Do JCOS products contain sulfates?

JCOS shampoos and conditioners are free from sulfated surfactants, parabens, and artificial ingredients.

I have an oily scalp, but my hair is dry and brittle from bleaching it so many times. Which JCOS collection should I use for my hair type?

JCOS products were designed to help you look your best regardless of  hair type, but some are better for certain concerns. For your hair type, we’d recommend using our claynal line. Over-cleansing to control excessive oil production in the scalp can leave hair dry, brittle and noticeably damaged. Our proprietary “Amino-Clay Formula” blends organic white clay, natural humin extract, and amino acids to activate detoxifying and healing properties in the scalp, removing impurities and excess oil, leaving a clean slate for hair to grow, and become nourished, smoother, and silkier. 

You can also mix and match our products for added benefits. Our Cafe Latte line is ideal for every hair type.  Our & honey line is excellent for split ends and dry, damaged hair as well.

My hair is very dry and tends to be frizzy. Which JCOS line would be best for my hair?

Our Ahola Butter line is excellent for thick, dry, and frizzy hair. Formulated from an ancient Japanese secret to the shiniest hair on earth, creamy butters and soothing herbal milk smooth thick, frizzy, and unruly hair leaving it glossy and silky.


Our & honey line is also excellent for dry hair. Like a refreshing and soothing sip of tea with honey, this luxurious and transformative honey based humectant cleanses hair without weighing it down or stripping it of its natural oils. Honey is the most hydrating ingredient on earth, and we’ve combined three different honey formulas in out & honey line.


Do you carry hair masks?

Our claynal SMOOTH SPA MASK relaxes and rejuvenates while detoxifying the scalp and moisturizing the hair. Botanicals and herbal extracts are released to create a relaxing, zen-like experience of the senses as lackluster hair becomes glossy, silky, and healthy. White clay surrounds every strand, allowing cashmere keratin, amino acids, and pure silk to penetrate the hair shaft from root to end, nourishing and repairing dry, brittle, and damaged hair after just one use.

Crafted with sulfate-free surfactants, our shampoos, conditioners, primers, masks, and oils are safe for color treated hair.
