What it is
A hair care series has been born from Koh Gen Do, which has been developing natural cosmetics that aim to combine "gentleness to the skin" and "functionality" since its founding. This is the Scalp Aging Repair Series, a hair care series for adults that contains a luxurious blend of naturally derived ingredients. This repair treatment was born from the idea of skin care, and approaches damaged hair from both the inside and the outside. It contains platinum silk* that penetrates into the hair, and the plant-derived ingredients react to the heat of the hair dryer to protect and care for the hair, coating each strand. It repairs hair to a supple, firm, and shiny state. With the gentle scent of natural essential oils, it gives a smooth finish. * Platinum and hydrolyzed silk <moisturizing ingredients> No fragrances, synthetic pigments, petroleum-based mineral oils, parabens, or alcohol. Patch tested. * This does not mean that skin irritation will not occur in all people.

This shampoo is not the refreshing mint or menthol type that is common in scalp shampoos, but rather moisturizing. It has a relatively loose texture and creates a fine lather. It is gentle on the scalp and makes hair smooth. I want volume, so using it alone is a bit unsatisfying. However, I really like the floral scent. It has a strong geranium scent, but it's not grassy, and the calming scent is soothing. If you add a little to Etvos scalp shampoo or Orbis fragrance-free medicated shampoo, it will not only smell good, but also add moisture, which is nice.
I bought this after trying the sample pouch and finding it to be a success. It's not so much a refreshing product as it is a moisturizing product that doesn't dry out the scalp. The shampoo lathers well, and the treatment has a light cream-like texture with a soothing tea tree and geranium scent. I wish the scent lingered a little longer. I lightly oiled my hair before blow-drying it, and it left my hair incredibly smooth and silky. It's a little pricey for continued use, so I hesitated, but it feels so good on the skin that I'll probably buy it again as a treat.
I used one bottle of shampoo over the winter. I thought it was too expensive for a shampoo, but I've been noticing my hair getting drier, probably due to aging. However, even with dry hair, my hair is incredibly healthy, so moisturizing shampoos tend to make it coarse and itchy, so I was looking for something just right. This shampoo addresses aging, scalp, and volume, so I figured it wouldn't leave any residue on my hair and wouldn't have a strong, weak cleansing power. I decided to buy it, and it was just the right amount of cleansing for both my scalp and hair, so I'm glad I did. It doesn't leave a silky smooth finish, but it gently removes dirt while leaving my hair and scalp just the right amount of moisture. It creates a rich, fine lather, but it quickly disappears after rinsing. I asked my regular hairdresser to use it during her treatment, and she commented on how well it lathers and rinses off. The scent is also wonderful, and I find it soothing every time. I like the subtle rose scent, mainly a gentle geranium scent that isn't too harsh. Since early spring, I've been using Lebelio Cleansing Relaxation, which I feel has a stronger cleansing power, but I'm stocking up on it this winter as well. While I'm happy to have found such a good shampoo, I'm also a little sad that I'm finally at the age where I can feel the effects of anti-aging products...
The amount is small and it's expensive, so I can't use it every day, but when I use it, I can see that it's very effective. Since the treatment is not applied to the scalp, I think it's the effect of the shampoo. First of all, the odor from my scalp has decreased dramatically, and my hair has become thicker and more resilient. It can cover the thin areas on the top of my head, which I'm concerned about, so I'll be using it again.
When you lather the shampoo, it becomes a dense, fine foam. The treatment has an easy-to-blend texture and you leave it on for 3-5 minutes before rinsing it off. When you wash it, it feels moisturizing, but when you dry it, the finish (dryness and manageability) is not that different from when you use your usual shampoo and treatment.
