What it is
An anti-aging conditioner that creates a moisturizing film on each strand of hair, bringing shine and manageability. Contains phytosterol, which fills in and repairs damage caused by UV rays, hair dryers, coloring, etc. with moisture. It fills up the cavities in the hair caused by damage and prevents frizz. Contains Inula extract, which approaches the stickiness caused by lipids in the hair and scalp, retains the shine and luster of the hair, and prevents frizz. The coating ingredient derived from hyaluronic acid forms a jelly-like moisturizing film on each strand of hair. It makes it difficult for the moisture you give to escape. Designed to adsorb to the negative charge of hair, it is silicone-free, yet gives shine, manageability, and a smooth feel. OSAJI's KAI hair care series is a silicone-free anti-aging care line that focuses on adult hair frizz. *Aging care refers to care using cosmetics etc. according to age. About the scent. The luxurious scent of damask rose and jasmine that is full of happiness. *Since natural ingredients are used, the color and scent may vary depending on the product unit.

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.
This is a reliable product that restores healthy, manageable hair to its former glory. I chose this conditioner for the following reasons: 1) Every few years, I suffer from unexplained, all-over hives, so I use cosmetics with simple ingredients to make it easier to identify the cause. OSAJI is my go-to. 2) Conditioners are applied and washed off immediately, so I'm concerned about their environmental impact. Therefore, I wanted a conditioner that doesn't contain overly stable ingredients like silicone. 3) And, perhaps due to age, my hair has become frizzy, and blow-drying it often lacks shine. If I get sweaty, it immediately feels like I haven't blow-dried it. So, I was intrigued by the product's anti-friction features. I wouldn't describe the effects as dramatic. It feels like my hair is back to the more manageable state it was a while ago, and I want that to be normal. However, compared to when I don't use it, my hair is more manageable and naturally moisturized without stickiness, making it easier to style even when I'm short on time. I'm impressed, and I can rely on it! The official OSAJI website says "Limited stock," so I'm worried it might be discontinued. The standard line was recently revamped, so I hope this one will be revamped as well. That said, the differences in ingredients between this and the new standard line conditioner are subtle. [Ingredients in KAI Liberation Conditioner that may make a difference:] ○ Tri (caprylic/capric) glyceryl... Forms a film without oiliness, and high molecular weight silicone provides damage care and smoothness without buildup, using plant-derived ingredients. ○ Inula extract... Creates a sebum film that adds shine without frizz. [The unique combination of ingredients in this product] Urea (hydroxyethyl urea) is a key moisturizing feature, and it's formulated with hyaluronic acid and cellulose in a form that easily absorbs them. It also contains a ceramide pseudo-ingredient. The luxurious scent of damask rose and jasmine oils is natural and lasts, leaving you feeling fresh and satisfied while using it. Although the amount of Inula extract mentioned above is small, it may be doing a good job, and there may be no substitute for it. I would like to continue using it as long as I can get it.
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.
