What it is
This hair mask is especially recommended for those who want to thoroughly treat damaged or dry hair ends, those who want to use salon-inspired treatments at home, and those whose hair is prone to damage due to daily use of curling irons and flat irons. It replenishes damaged, dry hair with moisture, leaving it shiny and smooth, with bounce throughout the day. It contains a high concentration of luxurious beauty ingredients, including high-pressure processed keratin, hematin, and royal jelly.

How to use
After shampooing, lightly drain the water and apply an appropriate amount (about two teaspoons for medium-length hair) to areas of your hair where damage is a concern, then leave it for a while and rinse thoroughly. You will see better results if you leave it on for about three minutes after application. Use two to three times a week as a guide. If using in conjunction with your favorite hair treatment, use it before your hair treatment. You can also use it daily instead of your hair treatment.

It was easy to use, but I didn't like the scent. I tend to place a lot of emphasis on scent when it comes to hair care products, so I won't be buying it again.
The sweet rose scent is perfect for me. It's a rich hair mask that clings to your hair and leaves it feeling moisturized. The high keratin content makes it a delight to use!
I found this at Tokyu Hands and bought it. I'm happy that it's reasonably priced yet contains a solid blend of ingredients. Hematin and keratin are important ingredients for hair care, but products with a lot of ingredients tend to be expensive, but this is truly affordable. It gives my hair shine and makes it manageable even in humid weather.
I finally managed to purchase this product. I think my favorite shampoo and conditioner and after-bath treatment are doing a decent job of caring for my hair, but at this time of year, it still gets a bit dry and brittle. I also dye my gray hair every month, so I purchased this as a special treatment to prevent damage from accumulating. This hair mask contains a high concentration of keratin, a key component of hair, hematin, which helps prevent color damage, and royal jelly, which helps maintain hair health. After shampooing, I lightly rinse my hair and apply it, and it instantly becomes lighter and easier to run my fingers through. It feels soft and silky even after rinsing. It also doesn't tangle easily when I blow-dry it. I was impressed by how soft and smooth it became all the way to the ends. It's recommended to use it two to three times a week, but since I have a bob, I don't need to use a lot at a time, so I think it might be okay to use it every time. I plan to buy more soon when I have less than half left to maintain the shape.
My hair is thin and curly without being too heavy, and the roughness has been reduced. It gives a moderate amount of shine. The finish is comparable to a 2,000 yen treatment. The scent is strong, but I don't mind it, so I give it a thumbs up. It's supposed to be a tupelo rose scent, but it reminded me of jasmine.
