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
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🫶🏻

Pros
Apply the curl cream generously, just like before using a curling iron. After using the curling iron, your hair will have a soft, bouncy feel.
Cons
The price is quite expensive. The fragrance might be divisive...it has a hint of fresh tomato.

Pros
This fragrance gives me a feeling of being cherished~ If I had the money, I would love to invest in myself. It has a light texture, is very moisturizing, and has no oiliness..!
Cons
There's no big effect or hair damage or anything like that. There is some effect, but the effect is rather minimal compared to the price...
Tip
I think it's good to use it mixed with oil!

Pros
This product is unparalleled when it comes to applying oil to wet hair after shampooing, drying, and finishing styling. It is not too heavy, yet it leaves the hair feeling moisturized and the curls long-lasting. Personally, I also love the scent - it's refreshing and exotic.
Cons
The downside is that the ingredients are not great, so if it touches the skin around the temples or the back of the head, it can cause skin issues. Considering the cost-benefit ratio, you might want to try a different product.
Tip
Be mindful of the ingredients and only use a small amount for styling dry hair. Applying it to wet hair and letting it get all over the skin can lead to skin problems.

Pros
This is a very popular product, so I decided to try it out for the first time. While the price is a bit high, I'm satisfied with it. The scent is like apples - not overpowering, but subtle and pleasant. It works well to replenish moisture in damaged hair like puffed rice cakes. The formula is non-greasy, applies smoothly, and absorbs quickly. Even though it's pricey, I would still recommend this product.
Cons
However, it only makes the hair look good for a day. Those who need more intensive hair care would be better off purchasing a high-concentration rinse-off pack and leaving it on for an extended period.

Pros
It is not heavy and finishes with a moist and soft touch. As it is for oily hair, most hair essences tend to feel a bit greasy, but this product does not, which I liked.
Cons
The price! It does not get sticky, so you have to apply a lot. That's why it gets used up faster.

Pros
Hello!!!! 1. Fragrance - Pleasantly sweet and enjoyable fragrance! When I first went to the hair salon, they put something on my hair and the fragrance was so nice that I became very interested. That's why I ended up buying it for the first time! 2. Moisture-rich Just as our skin needs the right balance of oil and moisture, I believe hair also needs moisture. However, most products on the market are mostly oil-based, so they only make the hair surface shiny without truly moisturizing it. But this product seems to moisturize the hair from within. I apply this essence first, and then coat it with oil, and this routine has been working well for me. The frizzy feeling has definitely reduced. Overall, the fragrance is great, there's no stickiness, and when applied in the right amount, it makes my hair feel soft and smooth! The price range makes me hesitate, but it's hard to give up this product. There aren't many alternatives, so for now, this remains my daily essential! As you can see in the photos, the 3rd photo shows my hair looking dry and frizzy, but the 4th photo (after applying the essence and oil, before drying) shows more defined curls and a healthy shine, don't you think?
Cons
I guess it's impossible for a good product to be inexpensive, huh? 😢 The price is really making me nervous when I buy it, but I just can't stop purchasing it..!
Tip
Using the Kérastase Genesis hair mask and then this product is an amazing combination.. 🫶 My husband even envies the softness and smoothness of my hair, the fragrance is so nice.. We keep buying and using them together because the results are so great, despite the high price range... I use the hair mask about once a week, and the hair essence every time I wash my hair!

Pros
After drying my hair, I can really feel the moisturizing effect. Other products leave residue on my hands even after washing, but Simon Thermique rinses off easily like water. I always apply the product and my hair feels calm.
Cons
The price is a bit disappointing. Since it's imported, that's probably why it's more expensive.

Pros
The spreadability and moisture seem to be good. The fragrance is also nice.
Cons
It's questionable whether it's really good value for the price. My hair is thin and prone to breakage, and while it seems to add moisture, I'm not sure if it's actually adding nourishment.
