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.

Improved hair health and appearance
I bought the 5ml sample size which was perfect - though it looks tiny it has lasted six applications for my shoulder-blade length, medium thickness, bleach damaged, heat-treated, perimenopausal hair. I had noticed a lot of breakage, especially near my crown. My hair always felt frazzled at the ends and just didn't look shiny or healthy. I used Head and Shoulders clarifying shampoo then K18 for six consecutive washes, followed by Redken Extreme Length leave in conditioner. You have to wait four minutes once you've applied the K18 then style as usual (no need to wash out). It's simple to use in the shower routine and adds no extra time - in fact it saves time as you don't need to use conditioner afterwards. My hair felt softer and healthier after each use and others have complimented my hair. It's not got any particular wow factor after one wash but my hair is now 100% in better condition. Broken ends are smoother and less noticeable, my hair looks so much shinier, fuller and healthier. I'll have a rest from this now but probably do another six washes after my next lightening session to maintain strength and health.

Tell me what kind of witchery is this !?
I wish I'd taken a before photo .I have been using £40 quid salon masks and shampoos and serums and nothing has been working to revive my fine, fried multi -bleached over- processed and breaking hair.I bought the sachets of Aphogee protein treatment on here a fortnight ago ,which was incredible and definitely helped stop the breaking and did make my hair feel and look so much better.I wanted to use it again because 2 weeks later my hair was back to looking flat and damaged,but but was advised not to due to 'protein overload' .I've been obsessed with finding a miracle since an expert hairdresser advised that my only solution was to get a pixie which I can't face ,as it took me 4 years to grow out my last short cut due to bleach damage to almost shoulder length but I just had to cut 4 inches off to disguise all the recent breakage from a semi permanent (that was not supposed to be damaging ) I bought this after tons of research and since it is only £6 I felt had nothing much to lose . The tube is teeny but I read that you only use a pea sized amount .In 5ml there is at least 4 applications left . The results have been ASTONISHING .Suddenly I've got my pre -dyed teenaged big hair back .It looks longer probably because of the fullness ,it looks like completely different hair.. I did use leave- in conditioner ( Peurology) after the initial 4 minutes , though it says not to use conditioner afterwards .It's shiny and has gone big and woofy with minimal styling and feels soft,I can barely feel the fried parts anymore and it's just doing all the right things Tell me kind of witchery is this !? I really hope results last .

Overpriced product for a temporary fix only
I was amazed at how ths product seemed to repair my curl pattern after the first use. I continued as directed for a further 5 washes and all was good. I intended to do as directed and use it as maintenance every 3rd wash . But the very first hairwash without it made my hair return to the frizzy mess it was before. I surmise that the effect of this product is only valid whilst it is in use after every wash and that the effect is simply a temporary fix. Extremely disappointing considering all the hype and the vastly overpriced cost of the product.

Great hair mask
Great item. I have quite dry damaged hair (uncoloured) & thought I’d give this a try. It was a bit difficult to get around just shampooing and no conditioner but it really detangled my wet hair and I got a brush through it fairly easy. My hair is very long and thick for reference. One small tube lasted around 4 uses so it’s great value for money.

Fantastic product
Wanted to try this before purchasing a bigger bottle. Absolutely worth the trial , I have shoulder length hair with a bit of colour damage and using this has made such a difference already after 2 washes . You need to place a small blob in your hand and rub together until this turns white use mid lengths to ends - you may want to use more depending on the length of your hair . Just amazing honestly worth the money so my next purchase will be a bigger bottle .

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.
