Really impressed with the product
This product give result on 1st use. Though I used less quantity mentioned on the description . it makes my hair little dry but dryness goes away when I use leave in conditioner and avocado oil after 30 mins. Hair feel stronger and softer. I dont know if it is okay not to use it on the 2nd wash. I posted question asking that. if I dont get answer I will use remaining product after one month. it is hella expensive. but it works with so little amount. So I will use 5ml as expensive spa once in a month.

ONE MONTH UPDATE
I hate using conditioners, masks etc as my hair strands just shed like anything and plus it’s so time consuming to leave it for some time and rinse it! So this product is an absolute necessity for someone like me! But the results are not as impressive as it reads in several reviews.. it’s just a replacement for a regular conditioner.. I used for about 4 washes and it did smooth my frizz out but if ur regular conditioner is doing this job just fine and if you are okay using regular conditioners then I don’t recommend buying this product because it definitely is expensive for just 5 ml … Update on my second purchase. This time around the product was a bit more runny! I have noticed the quality is usually being compromised when you keep buying from the same vendor or supplier on these market places and it is very disappointing. The quantity is also lesser than my first purchase!

All hype, no results
All hype no results. Extremely small for the price. Tried a few times considering there could be some user error but saw no results whatsoever. Don’t fall for the hype

Worth it
Quite expensive, results were good. Instantly hair was soft and noticeable change was there. Quality was good and bit of improvement was there in hair fall.

Clear and honest review here
Okay so I keep seeing people call this bad for a conditioner but its primary use is for bond repair. It is a bond repair product that works from the inside out so consistent use is required. Over time if you see how it improves your hair quality you’ll realise how brilliant this is. It doesn’t weight down thin textured hair and with one teeny tube it has made a difference in texture so I really don’t know what the haters are talking about. Please please please do read instructions and follow info by abbey yung online. It works!

K18 LEAVE-IN MOLECULAR HAIR MASK: risultati immediatamente visibili dalla prima applicazione
Forse ne abbiamo sentito parlare tutti, l’ultimo arrivato in campo di rigenerazione capillare. Si tratta di un innovativo trattamento peptico che rimpolpa i capelli e li riporta, come promesso, al loro stato di salute giovanile. Il suo punto di forza è la speciale molecola brevettata che si avvale della biomimetica per ricollegare le catene di cheratina danneggiate. Il trattamento K18 usa la formula della molecola peptide per riparare i danni causati da decolorazione e assicurare bellezza e benessere dei capelli, con risultati immediatamente visibili. Il trattamento K18 completo prevede il pretrattamento “professional molecular repair mist”, la maschera “professional molecular repair hair mask” che riduce la porosità dei capelli e ne liscia la cuticola e infine per completare il trattamento la maschera senza risciacquo “leave-in molecular repair hair mask” che è quella che ho provato. Devo dire che i risultati sono eccezionali. Setosità e lucentezza immediata al primo trattamento. I miei capelli sono ricci e crespi, per questo motivo vado dal parrucchiere tutte le settimane perché non sono brava con la piega. Con questo trattamento ho fatto la piega da sola, impiegandoci pochissimo tempo e con risultati per me eccezionali. Immagino si possano ottenere risultati ancora migliori con l’intero trattamento professionale, ma vi assicuro che già solo la maschera è spettacolare. Modo d’uso: la quantità da usare dipende dalla tipologia e lunghezza dei capelli, è tutto indicato sul cartoncino. Nel mio caso, per capelli lunghi e mediamente corposi, la quantità indicata è di 3ml, un po’ più del tubetto da 5ml. Ho lavato i capelli con uno shampoo normale, senza usare balsamo come indicato, li ho leggermente tamponati e ho applicato la quantità di maschera indicata, distribuendola uniformemente dalle radici alle lunghezze. Ho lasciato agire qualche minuto prima dell’asciugatura. Risultato : I capelli sono subito lucenti e setosi, ovviamente perdono un po’ volume e la piega tende a lisciarsi. Per me un risultato eccezionale, consiglio questo prodotto al 100%. Il prezzo del prodotto da 5ml è di euro 21,00 forse si trova a qualche euro in meno ma attenzione poi ai costi di spedizione. Il costo invece dell’intero trattamento (pretrattamento e maschera 150+150ml) si aggira intorno ai 220 euro, certo non sono pochi ma se si spendono per qualcosa che funziona e che risponde con risultati immediati, perché no. In alternativa si può anche provare il trattamento nei saloni e poi eventualmente decidere di comprarlo.

Si funciona pero si tienes mucho cabello solo te durará una puesta
Me ayudó muchísimo, me acabo de decolorar el cabello y esta mascarilla me ayudó mucho desde la primera aplicación para hidratarlo, en una sola puesta vi resultados PERO, yo tengo mucho cabello y muy largo por lo que me duró 1 puesta y nada más 🙁

Amazing product.
I love this product. I have blonde hair (not natural) and it can get very dry. I notice a different even after one use. Having used it for a while now it has made a massive difference to my hair. It feels soft and strong. I suffer from a lot of hair loss and it has also helped with this greatly. I don't have near as much breakage so it works well and does exactly what it says it does. It is a small tube but it goes a long way . It is a bit expensive but I believe it's worth every penny.

ABSOLUTELY worth getting!
I researched the living heck out of hair treatments, watched some Youtube vids, and Brad Mondo mentioned this (I think) for repairing bleached hair! Having done my hair silver, which was a major job since my natural color is quite dark and took multiple bleachings to get the yellow out) - THIS has given my hair new life! YES, it has to be reapplied twice a week (if you wash your hair more often, I don't and use a no-poo regime), but even this tiny tube will do the job and do it WELL! You only need a very tiny bit if you have super short hair like I do (ear length), and its absolutely worth it. It's left my hair silky and shiney. ^_^
