Pros
At first, I wrote with great admiration. I'll go in after eating about 70% of the scent~(the scent is truly good. I started sniffing uncontrollably). This was a product I found because my curls had become very severe, and the effects were above average, so I was very satisfied. (in the beginning...)
Cons
I'm allergic to it. It's still a relatively new product, but I'm too scared to use it. I've hidden it deep in my closet because I'm afraid I'll forget and use it again. 😢 When I use it, my face, neck, and arms itch until I wash my hair. (I have long hair..) Are other people who use this product not allergic to it? Why am I the only one like this? 😢
Tip
I only use a very small amount. (However, it causes an allergic reaction, so I have currently stopped using it.)

Pros
It has a slightly translucent and moisturizing texture! It has great spreadability and a wonderful fragrance.
Cons
The high-moisture effect is not incredibly powerful, but it's the best for daily use.

Pros
I really love it. It's a lotion formula, but there's no stickiness at all, so it's like applying a moisturizing lotion. I've been using it consistently, and for the first time ever, I received a compliment at the hair salon about how nice my hair looks (my hair was previously a bit damaged). The citrus scent is also very refreshing and I love it. I always apply it before blow-drying my hair.
Cons
The only flaw is that the price is a bit high. However, I continue to repurchase it regularly.

Pros
The scent is refreshing (like grapefruit? perfume) and it absorbs quickly into the hair. There is no residue left on the hands.
Cons
I'm not sure if this is as good as they say. It was supposed to be glossy and all, but it's actually a bit dry and fresh lol It's quite expensive too I'm not sure if it's as helpful as they claim There are a lot of good domestic products these days too... These days, I can only buy imported ones since direct purchases are blocked So it's really expensive....... The scent is kind of like grapefruit, but the effects are just so-so lol ; I think it's best to just find a product that suits you well.

Pros
I've been applying a leave-in treatment for some time now, and I've found an item that I'd like to stick with. First of all, the scent is just perfect for my taste. It's a citrus fragrance that's both refreshing and subtly sweet, almost making me salivate. And the formula is incredibly lightweight. Personally, I tend to apply a lot of product to my hair, so this lightweight formula works great for me. When I apply it, it feels like my hair is just drinking up the product.
Cons
The lid that rotates is inconvenient 😢 I keep dropping it. It would have been great if it was a fixed type. The small detail is disappointing 😢
Tip
Everyone knows this, but after towel drying, pat pat~ Don't let it touch the roots. And this one, when heat is applied, the active ingredients are activated, so be sure to apply it before heat drying!

Pros
I had used it before and remembered the scent being refreshing, so after using up the orange one (keratin thermal), I bought this again. The scent doesn't seem to be exactly the same as I remembered, and it's a bit different. It doesn't leave any residue on my fingers and fully absorbs into my hair.
Cons
I applied the product from the middle to the ends of my hair and dried it, but my scalp felt itchy. I wondered why that was happening, and after using it a couple of times and then stopping, it was fine. But when I used it again, it became itchy again. So I couldn't use it and just looked at it. I wonder who I should give it to. I didn't have that issue when I used the orange one, and I'm disappointed about that.
Tip
Apply the product section by section in small amounts. If you apply too much, it may become slightly sticky.

Pros
This is a product I received as a gift. 💙Fragrance I'm using this line of shampoo, ampoule, and treatment together as a set, and all the fragrances are great. They have a lasting scent. 💙No Heaviness Even when using a large amount, there was no heaviness or oiliness. 💙Absorption I liked that it absorbed quickly and lightly without leaving a sticky residue on my hands.
Cons
The price is expensive compared to the performance.

It's so convenient and comfortable because there's no need to rinse it off! The effects and fragrance are great too! And there's no greasy feeling left on the hands, which I really like.
Cons
The price is too outrageous 😢 Other than the price, everything else is great.

Pros
It seems quite good. The scent is nice as well. After using it, it feels smooth.
Cons
The ingredients are quite disappointing and the price is also disappointing. While using it, it feels fine, but I'm not sure about anything beyond that.

Pros
It's my absolute favorite! It's so moisturizing and has a subtle fragrance. I thought the 150ml size would be small, but it lasts much longer than I expected. Since I dye my hair frequently, it's much better than oil treatments - my damaged hair feels so much softer. I was looking for a moisturizing gel formula and this is the only one I can use now.. Oil-based products just make my hair feel stiff and the fragrance is not too artificial, which I really like💗
Cons
None..ㅠㅠ I wish there were more discounts on my favorite brand💖
Tip
Just blot your wet hair with a towel to remove excess moisture, then apply a generous amount✨ In the winter, I mix in a drop of oil as well🫶🏻
