What's in here?!
Wow! I've tried so many hair care products! I'm a beauty care product junkie. I've used very expensive creams and conditioners and masks and leave INS and this is by far the best! My hair hasn't dried yet from the leave in conditioner yet I feel compelled to write a review ASAP as my hair texture and damage feel transformed with one wash.

Instructions added to packaging
The instruction on the tube is Korean. It looks like they decided to just take a sticker and add it to the packaging in English. But if you don’t remember what’s in this once you open the packaging, then you lose the ingredients and the instructions so I suggest that they add that to the packaging. The product is a good quality and helps to tame frizz. It has a nice smell. I do like that they have the expiration date added to the sticker. This keratin pro booster. Treatment is good for color treated hair.

A Hard Pass…
Update: I used this treatment again for the second time and can fully confirm it tried out my mid to ends of hair. In addition, it caused a significant increase in tangled hair which in turn caused more hair loss. I cannot stand by this product whatsoever. It’s a hard pass for me and a complete waste of money and time. Original: I was truly hesitant to give this a shot, but alas gave in to my brimming curiosity. I read the instructions prior to usage on the brand’s website, since it was difficult to read the ingredients off the plastic packaging in such fine print. From what I’ve gathered, the texture was extremely thick which made me concerned it’ll weigh down my hair. I didn’t apply it to the entire head, just areas where I needed repair the most as per their website’s instructions. I applied it from mid to ends and left it in for five minutes. The site mentioned anywhere from 5-10 minutes. One thing’s for sure - I’m not a fan of fragrance/parfum and this had that artificial smell to it. While not all-out bothersome, it’s something to note for sensitive noses. While I’ve been battling with dry ends for eons now, the product felt like it helped alleviate that a bit. What I did notice though was between mid to ends, my hair felt more “tangled” and perhaps dry - which was weird. I didn’t follow up with a conditioner or mask afterwards as I felt this was supposed to be in place of them but who knows? Post-application, I’ve noticed much less hair fall. While not non-existent, my hair was better since I’ve been shedding like a sheepdog in recent months. As far as post-usage, I know for sure this product weighed my hair down (and I didn’t even apply it near my scalp and roots). Also, I’m uncertain whether this treatment works in place of a conditioner / mask or whether the latter should be followed up with. It wasn’t mentioned on Amazon and the brand’s site, so if someone can weigh in - that’ll be helpful. In addition, it wasn’t mentioned either how often to use this treatment - whether with every wash, weekly, bimonthly or monthly. The instructions should be made more clear and this was gathering off of the site. At this juncture, I’ll update my review at a later time as I continue utilizing this (though sparingly) and see how it shakes out.

Smells amazing and works wonders
I am really happy with this keratin hair mask. I feel like it really helps nourish my dried out and damaged hair. I've been using this hair mask once a week and I feel like I can see a huge difference in my hairs health. Also, huge plus it smells amazing as well. Only complaint I have is that the directions were placed on the outside packaging and the bottle itself is in Korean, so if you lose that you have no clue what you are doing.

I’m loving this brand so far. The hair mask gives a nice refreshing smell and also after one use I feel my curly hair feeling so soft.

同じブランドのカールクリームがよかったので、アウトバスのつもりで購入したんですが、、、 洗い流さないとありますが、商品裏の説明では、、、洗い流すタイプでした。 みなさまお間違えのないように。
