I would give it not just a like, but a hefty one)))) Love forever, everything that it promises itdoes. Personally, my hair is insanely stressed, it can fall out in clumps, the ends can simply be cut off by 10 cm and only with this mask they become more stable, so I love it very much and will take it again and again!)

Definitely improvement in hair structure and volume. Can't say I am a big fan of keratin mask smell! But otherwise great product!

The mask is very thick, bright mother-of-pearl blue, it smells of something obviously marine. It is applied perfectly and very economical: even one thick pea immediately makes the hair slippery, and after a minute of massage it is completely distributed over the entire head. However, out of greed, I squeezed out 2 peas :) Further: when using the mask right in the shower, a lot of hair begins to come out. I am not an alarmist, and I am aware that it is the hair that has already fallen out is washed out, but the fact itself speaks of the degree of �slipperiness� of the hair that the mask gives. I kept the mask for 5-15 minutes: sometimes I even left the shower with a bundle on my own business and washed it off afterwards. Right in the process of using it, you can feel how the hair is changing: it becomes denser, smoother, stiffer and more voluminous, and not fluid and slippery, as I used to with other masks. By the way! An important point - in the first two weeks I tried to use the mask as a balm, that is, every time and almost every day. Now, don't do this! Hair began to look dimmer and coarser. Twice a week is the best!

Advantages The best! Flaws They just don't exist A comment This is the best mask I've ever used (and I've tried a lot over the past two years). At some point, the hair began to break terribly, the products of this brand saved me :) In particular, the mask 4.3. A package of 200 ml is enough for exactly half a year, or even more, but 500 - for all 1.5-2 years :) The mask itself is blue, it smells very pleasant for me personally. Plus - it is even applied to the scalp (I feel calmer when not only the main length of the hair, but also the roots receive nourishment from the mask). Hair is not a bit oily, slightly smoothes, strengthens. Eternal favorite!

Ooh, Dixidox De Lux No. 4.3 mask is a super remedy that provides versatile benefits, which is doubly nice)) It also takes care of the scalp if there are problems with dandruff or seborrhea, stimulates hair growth if there is a problem with any type of alopecia, Well, the most pleasant thing is that it takes care of the hair, its structure thanks to keratin !!! The hair after the mask is healthy, voluminous and shiny, the feeling that the styling on the head does not fluff at all, there are hairs to hairs ... Mega-Remedy!

The best mask I have ever tried in my life. It is very convenient because you do not need to be afraid of getting on the roots, it not only does not make them greasy, but on the contrary gives volume from the roots. Hair becomes "elastic", shiny and smooth. We have been using it with my mother since March 2-3 times a week and the tube has not yet ended. I recommend to everyone!

Dixidox DeLuxe keratin treatment mask No. 4.3 Dixidox DeLuxe keratin treatment mask is my must have. I have naturally curly hair that tends to get dry. The mask solves this problem. Before applying, I blot my hair with a towel so that the mask does not drain and is better absorbed. I keep it for 15 minutes (if I apply only on the length) or 5 minutes (if on the length and roots). The mask does not make the hair oily at all, moreover, it rather refreshes and revitalizes them. My curls don't get frizzy after it, they lie neat and easy to comb. The mask is very thick and hard to squeeze out of the tube. I use 1-3 times a week, after shampoo 4.1.

I did not expect such an impressive effect from the "marine style" mask. It is convenient that it can be used not only along the length, but also on the roots. The roots after the mask do not look dirty, freshness is felt. At the same time, the length and ends of the hair become dense, smooth and very well-groomed. The best mask I have ever tried!

The mask is blue, I will not say that it is thick, of medium consistency. It has some kind of masculine-marine scent, pleasant, but not neutral. It is palpable, it remains for a short time on the hair (while they are wet, there is a smell, when dry I did not feel it). The mask is quite economical, low consumption, well distributed through the hair. I kept it for about 5-7 minutes, washed it off, the hair was noticeably smooth and soft even when washed off, and after drying, I was amazed at the result. The mask makes the hair heavier, this time, and I like this effect, because I have volume at the ends and roots, it sometimes looks strange (for me personally, I don�t like it). The hair is very soft, crumbly, obedient, smooth, shiny, and most importantly, they are somehow especially dense!!! The effect does not go away after washing for a while.

The mask is interesting, blue in color, very dense and thick, it is difficult to squeeze it out of the tube. The smell is pleasant, but weak, the shampoo eventually interrupts it anyway. After the shampoo, I blot my hair with a towel (if applied to wet, the mask flows down with water and there is almost no effect), I apply it along the length, twist the bundle and walk with it for about 5 minutes, then wash it off. The "glassiness" of the tips (after shampoo) immediately disappears, the hair becomes silky, but without excessive softness, easy to comb and very elastic to the touch.

Divine mask, I've been using it for two months now Dixidox DeLuxe keratin treatment shampoo No. 4.1 Dixidox DeLuxe keratin treatment shampoo - the hair is amazingly voluminous and shiny, it has stopped fluffing, it lies hair to hair and without ironing. Really like.

The best mask ever! The result becomes noticeable almost immediately. After application, the hair looks like after salon care. Feels like the hair becomes more elastic. Restores very well. Really stimulates hair growth.
