What it is
It avoids surfactants with strong degreasing power and contains a high amount of amino acid-derived cleaning ingredients that are gentle on skin and hair. It creates a smooth foam immediately and is easy to run your fingers through, so you can wash your scalp and hair comfortably. It contains Inula extract, which approaches the stickiness caused by lipids in hair and scalp, and keeps hair shiny and lustrous to prevent frizz. The conditioning effect of camellia oil and jojoba oil softens and smoothes hair. OSAJI's KAI hair care series is a silicone-free aging care line that focuses on adult hair frizz. *Aging care refers to care using cosmetics etc. according to age. About the scent.

This shampoo is amazing! I wish I'd found it sooner! I have soft, curly hair that tends to dry out. When I rinse my hair after shampooing, it gets squeaky and tangles around my fingers, causing a lot of hair to fall out. However, this shampoo lathers surprisingly well and doesn't squeaky after rinsing. The gentle rose scent is soothing. I don't have a store nearby that sells it, so I hope it becomes more readily available.
I use a shampoo and conditioner that costs over ¥10,000 and really like it, but it's a bit too expensive, so I searched for something better that was at least half the price and bought this highly rated product. I started by purchasing just the conditioner. I've been using it for about a week now, and after washing my hair, it feels soft and smooth, and the next morning it's easy to manage, and it looks great without any special effort. Honestly, I think it's comparable to products that cost over ¥10,000. It has a nice rose scent and isn't cheap. Given the effectiveness, the price is reasonable, so I plan to buy the shampoo next.
It produces fine bubbles and has a natural floral scent (like the smell of walking past a flower bed).
This shampoo lathers well and rinses off easily. I usually use salon-only products, but this shampoo is just as good. I would recommend it to people with all kinds of hair types.
The ingredients are gentle and the scent is natural, which is nice. It doesn't make my hair sticky and leaves it soft and moisturized.
