What miracles do not promise customers in exchange for a certain amount of money!
Descriptions are fascinating: "Lamination of hair, according to specialists, does not cause them any harm, on the contrary, the hair structure is restored. The procedure can be repeated an infinite number of times.
Such uniqueness is explained by the composition of the laminating mass.
"Valuable components nourish the hair, which not only makes it look healthy and shiny, but also gives it high flexibility and the ability to withstand mechanical damage, both when combing and when exposed to wind, frost, sea salt, etc.
Hair's pulp film allows it to breathe but blocks the removal of nutrients, proteins, vitamins, and moisture from the hair structure. Among other things, plant proteins are included in the laminating composition, they work in the hair and allow it to regenerate and grow more intensively.
Ooh, that's great!
Let's look at the promises in more detail. I will start at the end.
1. "...they work in the hair and give it the opportunity to recover and grow more intensively.
The first question I have is: How do the components "work" to make hair grow? A simple question: how? With a whip, are they standing next to each other?
The hair has two parts - the visible part is the hair shaft and the root.
Hair root (bulb) is in a kind of hair "bag" - a follicle, which in turn is located in the hypodermal layer of the skin (at a depth of 3 to 6 mm.).
In the hair bulb, there is a continuous active mitosis (division) of cells.
Growing or mature cells gradually lose their nuclei and keratinize (flattened and lengthened). The pressure inside the follicle due to continuous mitosis "makes" the hair grow upwards at an average rate of 0.3-0.4 mm per day.
The follicle is suitable for blood vessels, which "supply" the necessary substances to nourish the hair, i.e. provide the center of cell division with the necessary "building material". After the hair cell has formed and keratinized (left the follicle), it no longer receives any nutrition from within the body.
And how can I know if the wonderful substances from the laminating composition (how "wonderful" it is, let's see below), which is applied exclusively to the length of the hair, make the hair grow more intensively?
After a broken bone, you can just as easily anoint your arm or leg with cream or ointment in the hope that the splicing will intensify.
And it's funny about "recovering". Thickened keratinized (essentially "dead") cells will begin to regenerate? Frankenstein is resting.
2. "The components nourish the hair, which not only makes it look healthy and shiny but also gives it high flexibility and the ability to withstand mechanical damage...".
The hair shaft consists of 3 layers:
- The brain layer is the core of the hair, which consists of 2-4 layers of unburdened cells of cubic shape.
- Cortex is the main part of the hair, consisting of longitudinal rows of keratinized cells, which provides the hair with strength and flexibility. Its composition is 90% keratin, a protein substance. This layer contains the molecules of melanin, the hair pigment.
- The cuticle is the top layer of hair, a kind of "shell" that protects the cortical fibers and holds them together. This layer consists of 6-10 layers of elongated keratinized plate-shaped cells, which like tiles overlap each other in the direction of roots to ends.
The edges of the shell scales on the newly formed part of the hair are smooth and intact. As the hair grows farther away from the skin, the shell begins to get damaged and break (when washing, combing). This process is strongest after the hair has been dyed or permed, and the scales of the hair are already damaged and easily detached from the hair shaft.
What happens during lamination?
The essence of the lamination procedure, however it may be called, is to coat the hair with a colorless or colored composition of substances (usually based on hydroxyethylcellulose), creating a persistent film on the surface that "protects the hair from the negative effects of external factors".
Everything would be fine, well, "put on" the hair in another layer, which is bad, because "...the cellulose film covering the hair allows it to breathe, but blocks the removal of nutrients, proteins, vitamins and moisture from its structure.
Blocks the output... A logical question: what about the introduction? If the hair fibers are damaged, do they need to be replaced? No, instead we cover the hair with a dense cellulose film.
It's like a dry, flaky skin instead of moisturizing creams and masks (and the top layer of the epidermis is also made up of "dead" keratinized cells), wrapped in a plastic bag.
In addition to protection against "negative" effects, the cellulose film also protects the hair from positive effects, such as the "introduction" of supplements (masks, balms) into the structure of the damaged rod.
