Hair type: Dry, combination (oily scalp with dry ends)
Hair concerns: Frizzy hair, unruly/unmanageable hair

After trying the Kiseki Leave-In Hair Masque, I was honestly surprised by how much more manageable my hair became. This product is mind-blowing and I genuinely wish I had discovered it earlier!
I used to get comments about how unruly my hair looked, with people comparing me to a lion. I often had to tie it up just to avoid remarks. But now, I can confidently wear my hair down in the office without worrying about it looking wild. It’s really helped boost my confidence.
Unlike hair oils that stink after opening or leave my hands greasy, or other leave-in creams that just weigh my hair down and clog it, this one is completely different. My hair feels smooth, manageable, and smells amazing. There’s no greasy residue, just light, fresh fragrance that even my husband noticed!
He asked if I had changed shampoos because the scent was so nice. I could even smell it on my pillow. My hair is now much smoother and I don’t struggle with tangles anymore.
Not gonna lie, but this is by far the best leave-in hair mask I’ve ever used! I’d absolutely recommend the Kiseki Leave-In Hair Masque to my friends and family.

After just two uses, I was genuinely impressed. My hair felt noticeably smoother and softer, with less frizz and more manageability.
And the scent? It’s one of those clean, comforting smells that lingers just enough. Honestly, I didn’t think I’d notice a difference so soon. I keep catching it throughout the day and it just makes me weirdly happy.
I wasn’t expecting much at first, but after the second use, my hair feels so much smoother, like I can actually run my fingers through it without them getting stuck. It also feels more manageable during styling, and it takes less time than it usually does.
I love it a lot and I definitely enjoyed using it on my hair. Most importantly, it didn’t leave any greasy residue when spritzing it on my hand. Overall, it felt like a small luxury that was actually delivered.

Hair type: Combination (oily scalp with dry ends)
Hair concerns: Frizzy hair, colour-damaged hair, heat-damaged hair (e.g. perming, rebonding), dry and brittle hair, unruly/unmanageable hair, split ends

After just one use of the NatureLab. TOKYO Kiseki Molecular Repair Leave-In Hair Masque, I noticed my hair stayed smooth and frizz-free for about two days. It felt more nourished and moisturised at the ends, and also appeared stronger and less prone to breakage.
I’ve only ever used rinse-off hair masks, so having one that provides the same results without the need to rinse is a huge plus, one less step to complete!
I liked that this hair mask also functions as a heat protector when I blow-dry my hair. That’s something I’ve never experienced with my rinse-off masks.
It was also my first time using a hair mask that didn’t require rinsing off and I had to skip conditioner too, which definitely took some getting used to. Nonetheless, I liked how easy it was to use. It felt more like I was applying a hair serum than a mask.

It smells amazing, and the best part is that there’s no need to wash it off. My hair feels tamed, and I don’t have to keep combing it throughout the day to keep everything in place. It also feels moisturised, softer, and healthier.
After just one week, I feel so much more confident about my hair. It’s easier to manage after just one use, and it both looks and feels noticeably smoother and softer.
