아미노 애시드 샴푸

My scalp is combination, so I prioritize fragrance, and while it's not as good as Lush products, I'm satisfied.

The fragrance is just right, and it seems mild, but the cleansing power is good.

I was using it and loving it, but one day when I scratched an itchy spot, I found that my dandruff had gone crazy. The flakes were huge and hard, rolling around, and the dandruff layer was so thick that no matter how much I scratched, more just kept coming out - big chunks of it. Soon after, my scalp inflammation flared up, and I had to take steroids to recover. I wondered if it was because of this shampoo, so I started using other shampoos and only used this one about twice a week, but on the days I used this shampoo, the dandruff and flakes would explode. I really love the fragrance and the rich lather, but it's such a shame.

The fragrance is so lovely. When I wash my hair at night, the subtle shampoo scent that lingers in the morning helps lift my mood. The lather is also abundant, making it easy to wash my hair.

At first, it was gentle and my scalp felt comfortable, but a couple months in, I started getting some occasional buildup on my scalp. It seems a bit too mild to properly care for my scalp. Additional treatment is necessary.
While it's not very functional, the price is still on the higher side, and my hair feels a bit stiff, likely due to the effective cleansing. This is a shampoo that requires using a good conditioner.

I have a sensitive scalp and occasionally experience scalp issues. I purchased this shampoo from Rene Furterer, hoping to switch to a better formulation.
The cleansing power is better than expected, and it lathers up nicely. 
The lather feels very gentle and soft when rinsing. After switching, my scalp was not itchy and felt soothed for a while.
This is a mild and unremarkable shampoo. I would recommend it if you don't have troublesome scalp issues.

Even after shampooing, if you don't thoroughly massage the scalp, the scalp odor doesn't completely go away...

1. Excellent lather
2. Can be shampooed without conditioner, even with Barbie doll hair

I wet my scalp with lukewarm water, apply the shampoo, and wait for 2 minutes while massaging my scalp. When I used cheap shampoo, I rinsed it off quickly, but this one is high-end, so I rinsed it thoroughly (haha). By doing this, the scalp cleansing and hair strengthening effects seem to be even better. I also bought the amino acid conditioner, which is also great. These two will be my lifetime products.
I recommend buying them when they're on sale.

The price (haha) (rolling) But since this is the shampoo I've been looking for, I bought the 1L shampoo and conditioner to make it my go-to product.

Although my face is dry, my scalp is oily, and I often had a lot of pimple-like things on my scalp. But after using this, the cleansing power seems to be good, and my scalp troubles have been relieved. For some reason, my hair also feels stronger.

I have an oily scalp type that needs to be washed daily, but when I use this, the oil seems to come back faster in the afternoon. The cleansing power is so-so, so I would recommend this for a mild oily or normal scalp type.

The fragrance is nice and the cleansing power is not bad either. The ingredients are better than regular shampoos.

Please don't use it, I wonder how such a rating came out..

It's a slightly acidic shampoo, but after using this product, my scalp became oily quickly and I had a lot of skin problems on the back of my neck and behind my ears.. How can it be worse than Dove soap?

Vanilla fragrance and simple design, overseas brand Kiehl's logo, etc...

I'll need to rinse it thoroughly several times.

The downside is the price, of course. Unless it's a gift, the purchase would be burdensome for me.

I tried the product after receiving it as a gift. It seems to be about the same as before in terms of my dull scalp.

Be sure to pair this shampoo with a 2,000-3,000 won scalp brush for best results.

The lather doesn't get very thick, so you need to use a sufficient amount. It works best when used together with a scalp brush to get the full synergistic effect.
The cleansing power is so good that it can leave your hair feeling a bit stiff, but this can be remedied by using a hair treatment just on the ends.

I have an oily skin type and an oily scalp.
Shampoos are often hit-or-miss for me, as my hair tends to get very greasy by the afternoon. However, this is the only shampoo I've tried that doesn't leave my hair feeling overly oily.
The scent has a coconut-like fragrance that could be perceived as a bit greasy, but when used with the scalp massage brush, the cleansing power is great and my hair doesn't get too oily throughout the day.
Normally, if I wear a hat after using regular shampoo, the front of my hair gets greasy very quickly. But when I used this shampoo and then wore a hat, my hair stayed decent until the evening.
This is a must-have item to stock up on at the duty-free shop.

It's a bit drying
Without using conditioner, my hair feels a bit rough and coarse.

My hair is definitely shedding less
It's weak, thin, and frizzy, so it's the epitome of messiness, but this shampoo is quite nice for someone like me who is always on the go.
