With the first application, the difference was obvious! My hair is more hydrated, voluminous, and looks stronger... I hope for even greater improvement with frequent use...

the first time I used it, it didn't make any improvement to my hair. note: I have thick and unruly hair.
the second time (from the same bottle) I used it after rinsing out the hair dye. probably because the hair cuticles were open, it worked perfectly and has softened and smoothed my hair so much that I was thrilled.

If you use it correctly according to the instructions, you will see your hair transform. I did highlights and they haven't been affected at all! They are so soft and resilient as if they haven't undergone any chemical treatment.

After 2 applications, I already think it has worked, especially in combination with a good hair mask. Recommended!

Amazing treatment that lasts. It's been years since I felt my hair so soft and at the same time with volume and a very light feeling!! Usually, if a product makes my hair this soft, it also weighs it down a lot. Not this product! I definitely recommend it!!!

It gives a beautiful result to the hair, they look smoother, healthier, stronger, and shinier. But it shouldn't be used frequently. I will definitely buy it again

Before I did highlights with bleach on my very fine hair, I would say it was an excellent product. However, the last time I used it I wasn't thrilled. Nevertheless, I would buy it again even though there are better ones out there.

Fantastic product!

Having used both Olaplex and K18 in the past, I can easily say this is the best of all!
After 1 month of use, I noticed much less hair breakage, and my hair generally felt stronger. Only this way was I able to grow it longer, even though I had been trying for years.
I highly recommend it!

Very good! I used it for the first time after my hairdresser's recommendation, and my hair has become stronger.

I've been using it for a year now. At first, I thought about giving up because I didn't see anything happening except for the softness it gives to my hair on wash day. However, I persisted and used it since I had bought it. So, with weekly use on dry and damaged hair from bleaching, I had lost hope that it would ever grow back below my shoulders. I have to say that in one year, it finally grew as much as it has never grown in my life, and it continues to grow normally! For me, I believe it's worth it; I saw a difference, but it just takes time and patience. Don't expect to see results from one day to the next. I will definitely buy it again, and this time I will also try the K18 for the first six washes after bleaching, and for the rest of the time, I will use this.

Much better than Olaplex. It helps the hair a lot from the first time; after 1 month of use, I see very good results

I bought it because my hair is breaking, I have split ends, and generally dry-damaged hair. It doesn't work miracles (as expected) but I can say that it is one of the few products that I actually felt a difference from the first use. I mean, my hair felt softer and shinier. I would buy it again, although I would like to try other brands as well. It's worth experimenting.
