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 natural ingredients. This scalp care shampoo is based on the idea of skin care, focusing on the scalp cycle and keeping the scalp healthy, leading to ideal hair with elasticity and strength. It contains plant-derived cleaning ingredients and collagen*, and washes while moisturizing and protecting the hair. With just one bottle of shampoo, not only does it address adult hair concerns such as frizz and dryness, but it also gives you fluffy, voluminous, shiny hair every time you use it. You can achieve a satisfying finish with just the shampoo. * Cocoyl hydrolyzed collagen K <cleaning ingredient>, hydrolyzed collagen <moisturizing ingredient> No silicone, 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.

The shampoo is silicone-free. It foams well even with a small amount, and is easy to wash without any roughness. The treatment reacts to the heat of the hair dryer and protects the hair. The scent is natural essential oils. It smells like rose or geranium, and the scent doesn't linger much after drying. I've gotten used to pump-type shampoos, so it's been a while since I used a package with this shape. It's surprisingly easy to adjust the amount. Both seemed to suit my hair. I would buy them again if they were a little more affordable.
The amount is small and expensive, so I can't use it every day, but when I use it, I can see that it has a great effect. Since the treatment is not applied to the scalp, I think it's the effect of the shampoo. First of all, the odor of the scalp has decreased greatly and my hair has become thicker and more resilient. It can cover the thin areas on the top of my head, which is a concern. I will use it again.
I haven't had a haircut since last year, so my hair has grown down to my back. It's now semi-long and has lost volume. However, I ordered Koh Gen Do's shampoo and conditioner on a regular basis, and when I tried using it, I was surprised at how my stiff and thin hair felt after washing. My scalp felt refreshed, the volume increased, and even when I went out in the rain that day, the finish was almost the same.
I received this from suzykirei. Thank you. The shampoo comes in one-push type. It's convenient to be able to open it with one hand, but I'm a bit concerned about hygiene. It's silicone-free, but I can use it without any squeezing. The treatment comes in a cap type. Even a small amount spreads well and is easily absorbed. There was no stickiness after washing. When I use a hair dryer, it becomes shiny and creates an angel halo! My hair has become easy to manage! It's a little pricey, so I think it would be easier to continue if it was a little more affordable!
I bought this because I liked the sample pouch. It's not so much refreshing as it is moisturizing and doesn't dry out the scalp. The shampoo lathers well, and the treatment has a light cream-like texture, and the scent of tea tree and geranium is soothing. I wish the scent lasted a little longer. I used a light hair oil and then dried my hair, and it became incredibly smooth. Moist and smooth. It's a bit expensive for continued use, so I'm hesitant, but it feels so good to the touch that I'll probably buy it again as a reward.
