✨ "Best Hair Straightening Treatment!"
I am extremely impressed with the Kativa straightening treatment! It was very easy to use and the instructions were simple to follow. The results were even better than I expected — my hair came out smooth, shiny, and perfectly straight without feeling damaged. What I love the most is that my hair feels soft, frizz-free, and so much easier to manage. The effect lasts a long time, even in humid weather. It truly looks like a professional salon result! For the price, the quality is excellent. I will definitely buy it again and highly recommend it to anyone looking for a long-lasting, gentle, and effective straightening treatment.

Perfect for hair
Perfect, for someone was looking easy to manage It takes long time to apply, but you get the best result, and if you want to maintain it, do it every 3 months, you'll see it is always straight and looks perfect. Ready to go and the best part is , it doesn't damage your hair

smoother, softer, and frizz-free.
This Kativa Brazilian Straightening treatment works very well. From the first application, my hair was smoother, softer, and frizz-free. It doesn't have a strong odor and doesn't damage the hair. It's easy to apply at home. Excellent quality.

Takes a bit of work but very worth it. Works well!
My obsession with keratin began years ago when I was living in Korea and came across a keratin serum that transformed my hair, but this is the first time Ive done this kind of treatment. Decided to go for it so I could air dry my wavy hair without having to smooth out the kinks with heat every day - Id definitely say I achieved that with this product, and the added shine and silkiness this gave my hair is crazy. You REALLY want to make sure you take your time, blow dry the product completely (this does take some time!) and then straighten in small sections. The more time you give this process, the better your results will be. I did the minimum amount of passes the instructions said as I didn’t want stick straight. Love, love, love.

Great keratin, perfect for curly hair and sensitive people
I have curly hair, and this keratin worked very well for me. It made my hair very soft, smooth, and much straighter. My hair looks shiny and feels healthy. One thing I really like is that it has no strong smell. I am allergic to regular keratin products, but this one did not cause any irritation or allergy at all. I highly recommend this product, especially for people with sensitive skin or allergies. It is a very good product and worth buying.

It gets rid of frizz and lasts
It works pretty well and the entire process takes about 4 hours. The only thing is I have really thick and long hair so next time I get it i'll buy 2 because it didn't fully cover all of my hair. It lasted the 12 weeks and still has some slight affects in my hair afterwards so I do like its longevity. I mainly got it because no matter what I do or what product I buy my hair is frizzy, but this kills the frizz and its amazing for that. It also stains clothes like bleach does so be careful with what you wear when you use it.

Professional results with a fraction of the costs
I had the opportunity to try this product on my curly hair (3C curls, spirals, and waves). I was prepared to take the time that other reviewers mentioned would be needed to go through the entire process. It took me about 3.5 hours and I have hair that goes past my shoulders when curly and to my chest when straightened. The process is long and I followed it diligently which I think is key to getting the desired results. I even went through small sections of my hair with a straightener for a minimum of 8 passes. It was tedious and I was still skeptical about the results. And since you don't know how the hair will turn out after putting in all the time and effort it felt like a bit of a gamble. As the last step, I washed my hair and put conditioner on it and could immediately feel that the texture of my hair changed. Usually when wet, my hair still has curl - they're elongated but still there. After using the product, going through the process, my hair when wet was straight. I let it air dry because at this point I didn't have it in me to blow dry my hair after 3.5 hours. And WOW - it was slightly wavy but mostly straight - definitely would be easy to have blow dried my hair straight with the results that I got. I've had the Brazilian Blowout done professionally and the results with the DIY kit were nearly the same. I say "nearly" only because I could see the benefit of having someone else help with doing this as the back of the hair can be tough to make sure you've gotten enough product on it and you've properly passed through it with a straightener. I'm really happy with the results and when I air dry it looks like my hair has natural beach waves (which is what I remember when I got it professionally done). It takes a bit of time and effort, but is worth it if you want to avoid spending $$$ at the salon. As others have mentioned, when you straighten with the product there is smoke and a smell. I didn't notice the smell until I was closeer to my face, but saw the smoke during every pass. Do this in a well ventilated area.

INTRODUZIONE Ho deciso di provare il kit lisciante Kativa dopo aver cercato una soluzione più economica rispetto al salone, dove avrei dovuto spendere circa 150 euro per un trattamento. Avendo i capelli molto mossi, lunghi e difficili da gestire, ero curiosa di vedere se il prodotto avrebbe funzionato. Dopo aver atteso diversi mesi per valutare a fondo i risultati, posso dire che il kit ha superato le aspettative! RISULTATI DOPO IL TRATTAMENTO I miei capelli, ormai diventati indefiniti e ingestibili, hanno ritrovato ordine e struttura. Prima dovevo sempre utilizzare la piastra per tenerli in ordine dopo l’asciugatura, con questi prodotto ho risolto finalmente. L'effetto lisciante è stato immediato e ha resistito per quasi 3 mesi pieni. Ora sono trascorsi 4 mesi e il trattamento ha quasi del tutto perso efficacia, ma intendo ripeterlo presto perché i risultati iniziali sono stati straordinari. PROCEDIMENTO Procedimento: lungo ma non complicato Il procedimento richiede tempo, ma non è affatto complicato. Bisogna seguire attentamente le istruzioni per ottenere un risultato ottimale. Un avvertimento importante riguarda il fumo che si genera durante l’asciugatura dopo l’applicazione della maschera: è davvero tanto e l’odore è piuttosto sgradevole. Per evitare fastidi, consiglio di indossare una mascherina e, se possibile, eseguire questo passaggio in un luogo ben ventilato. Io, ad esempio, ho asciugato i capelli sul balcone per evitare che la casa si riempisse di fumo. Se non avete una zona esterna, fate attenzione a farlo in un’area ben arieggiata. Questo piccolo accorgimento renderà l’esperienza più sopportabile. CONSIGLI PER L'APPLICAZIONE Un passaggio fondamentale è stendere il prodotto in modo uniforme dalle radici alle punte. Ho notato che nella parte posteriore, vicino all’attaccatura, non ho applicato correttamente la maschera, e in quelle zone i capelli sono rimasti leggermente mossi. Fare attenzione a questo dettaglio è essenziale per ottenere un risultato perfetto. CONCLUSIONE In sintesi, il kit lisciante Kativa è stata una vera svolta per la gestione dei miei capelli. È un’alternativa pratica ed economica ai trattamenti professionali, garantendo risultati visibili e duraturi. Lo consiglio assolutamente a chi desidera capelli lisci e facili da gestire senza dover spendere una fortuna. Con un po’ di attenzione nell’applicazione, il risultato sarà impeccabile!

J’avais vraiment des doutes sur l’efficacité de ce produit surtout vu son prix alors que chez la coiffeuse je paie 190 euros pour cheveux longs. Et bien, les résultats sont impressionnants. Mes collègues de travail pensaient que j’étais allée chez le coiffeur. Mes cheveux étaient vraiment lisses et soyeux pendant à peu près 2 mois. J’ai acheté le shampooing et le conditionner de la marque et je ne regrette aucun de ces achats.

C'est la 1ere fois que j'utilise ces produits. Très bien. Attention à bien aérer, bcp de fumée avec le lisseur. Bien se protéger le cou et oreilles ça pique. C'est très long quand on a bcp de cheveux. Très contente du résultat, mes cheveux sont souples et doux et brillants. (j'ai les cheveux très épais et bcp de volume.) ça a marché pour moi. Je suis sortie avec sous la pluie, ils ont pas gonflés!
