So, we meet a mask for hair "Mustard" from DNC.

This mask is intended to wake the sleeping hair bulbs and to force to grow hair. On how many it copes with the functions, let's look together.
Packing. What can it tell us? It is a brown box on which face, we see the name "Mustard", an emblem of "DNC" and an inscription that this mask is intended for rapid growth of hair.

On one of lateral faces action of a mask is described

On the back packings the means method of application, and also structure is described. On it I will not stop it is already visible that structure remarkable, all vegetable, natural.

We open a box and we see in it two bags on 50 grams everyone.

In bags powder, such dairy-grayish color (on another I cannot describe), almost flavourless contains. By sight homogeneous mass.
Application:
This powder needs to be filled in with hot water, but not boiled water. The mask has to gain consistence of dense sour cream

After I "made" a mask, saw that the mask is similar to that mustard which is on sale in a jar for consumption))) Unless differs in color.

Now weight should allow to cool down to a comfortable state what when drawing would not be hot. The mask needs to be put closer to roots of hair, and here it is better to leave tips without mask to avoid "redrying" of hair. But if you have hair already dry, then this mask it is recommended "to trouble" warm milk or vegetable oil, and it is possible also kefir.
But I did a mask with usual water, sometimes added a drop or two any efirka. After drawing means on the head, dressed a polyethylene bag and from above wrapped up with a towel. The producer recommends to hold a mask of 5-20 minutes and if you comfortably and do not have discomfort, then time of the procedure can be prolonged up to 40 minutes.
What I also did as the mask of negative reactions did not cause in me, and there was light, pleasant heat. Though, reading reviews of girls of this mask, I know that at much it baked the head that not everyone will sustain. And I have skin the head probably through chur thick, so her this mask, pepper do not "punch". I easily maintained 40, and even 50 minutes then washed away means a dyed hair DNC shampoo. Special work to wash up a mask from hair did not make work, probably because I have short hair. Besides, returning to other responses, girls wrote that the mask is washed away difficult. But also here I was lucky, much more difficultly to wash up the Hop mask of the same brand.
One packing of a mask for rapid growth of hair "Mustard" was enough for me for 8 applications as I divided one bag into two times. This quantity is quite enough for my hair. Did it once a week, as well as the producer advises. That is one packing lasted for two months of application. By the way, absolutely forgot, at a washing of a mask it is necessary to be very careful what God forbid water with a mask would not get into eyes, otherwise will pinch so that "mother do not grieve". But if nevertheless it occurred, then eyes need to be washed out urgently a large amount of clear water.
Conclusions:
What I can tell about efficiency of a mask... I did not notice obvious, that is rapid growth of hair, here the Yeast mask copes much better. But, certain "underfur", that is tiny volosik nevertheless appeared, they are felt to the touch when you run fingers over head skin. And also well cleans hair, after application they look healthy and well-groomed, gryaznitsya less. Reduces a hair loss.
