Pros
Intoxicated by the fragrance, I used the product for a while. The effects were good, but I didn't see any dramatically noticeable effects.
Cons
The prices are steadily rising, and it is disappointing that purchases can only be made online.
Tip
Try the fragrant black oil that appears here instead of Kerastase Simonline. It's my first time.

Pros
The Hwahae hair treatment I bought after seeing the advertisement featuring Jang Won-young was actually quite good! To be honest, the price range was quite high, so I hesitated a bit when purchasing it, but to sum it up, although it is expensive, the effects are certainly worth it. My hair type is originally thin and prone to breakage, so I've tried quite a few hair treatment products, but this one was noticeably different after using it. My hair feels much less damaged, and when I touch it, it's much softer and calmer. I think those who frequently use heat styling tools or have damaged hair from frequent coloring or bleaching will especially feel the effects. The application is smooth, and the scent is luxurious, so it even puts me in a good mood when doing home care. There was definitely a sense of premium satisfaction.
Cons
Undoubtedly, the price is too expensive. However, on days when you want to invest in your hair, this product is worth trying out! If you have thin and easily damaged hair, I can sincerely recommend this.

Pros
My straight hair is too fine, so even just using a hair dryer always leaves it damaged. But when I apply the essence, I was able to grow my hair quite long without any damage. It has a white lotion-like feel, and there's no stickiness at all when applied to the hair. Even though I have an oily scalp and dry hair, it doesn't make my hair feel heavy when I use it.
Cons
The formula is a lotion, but it is used excessively. It is expensive, but I highly recommend it.
Tip
Applying it to the ends of damp hair and applying heat will provide protection, making the hair stronger.

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'm glad to hear that you've been receiving nice compliments about your hair. You've been using Kerastase pink shampoo, Simontermic, and the original Elixir Ultime, and your hair has become very calm. You used to go to the hair salon every 3 months for treatment, but you haven't done that in a long time. Now you're getting compliments on your hair condition, and you're really happy about it. Before, you tried a lot of different shampoos and essences, but your hair would get troubled and itchy. But now, thanks to Kerastase, that's not the case anymore. You plan to continue using Kerastase products going forward.
Cons
Well, the price is a bit on the expensive side, so it might be a burden.
Tip
Don't pull your hair too vigorously when drying it. Just gently pat it with a towel, apply some product, and let your hair air dry. Avoid using overly hot air to dry your hair.

Pros
For the past 4 years, I've been using it consistently. Aside from the high price, there are hardly any downsides. Since there is no better alternative for permed hair, I've been using it consistently.
Cons
The price is expensive. I usually purchase it when there are sales events on Naver or at duty-free shops, as it tends to be cheaper there.

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.

Pros
The heat protection treatment was the best. This one alone is enough to make my hair feel soft and smooth.
Cons
The price is really insanely expensive. On Olive Young, it's around 40,000-50,000 won, but if you buy it on Coupang or directly import it, you can get it for around 40,000 won.

Pros
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.
