Here there are means that either nourish or restore hair. Look at the bottle and its contents do not understand the difference - why this tool restores the hair structure, and the other - feeds them?
In fact, the difference in these two procedures is huge. And after this article, you will acquire exactly the essence of restoring and nourishing hair treatments.
We turn to our hair anatomy.
It consists of keratin (about 90%) - is a natural protein that is responsible for the structure of our hair.
Keratin, like any protein consists of amino acid chains. Chains are connected by three bonds:
- hydrogen;
- salt (ion);
- disulfide.
Hydrogen bonds - the weakest. Destroy them easily, you just have to water or heat the hair. But they themselves can be restored. Due to the hydrogen bonds, we can get the curls, if clocked wet hair in curlers, but if during the day get wet hair - curls disappear.
Salt communication - too weak. They are destroyed by even a slight change in pH. In other words, a change of shampoo, homemade vinegar and onion mask, painting - all this destroys the ionic bond.
Disulfide bonds - the most powerful. To destroy them, it requires high temperatures, perm. These links two chains of amino acids are combined into one because of cystine. A cystine - a sulfur compound and the adjacent cysteine amino acids.
Hydrogen and salt bonds can recover on their own. But disulfide - no. More specifically, they may, for example, to recover due to oxygen after the high temperature. But oxygen oxidizes sulfur and converts cystine to cysteic acid, which eats away the keratin and destroys it.
After the destruction of the disulfide bonds is necessary not only to restore them, and more, and the protein itself. More precisely - re-synthesize protein. But this is unreal! There are no tools that would restore keratin!
But it is possible to forestall and prevent oxidation processes break down keratin. It is capable of maleic acid. Nothing more. Well, even the salt of maleic acid helps restore the disulfide bonds and not to break protein.
Such discovery came Olaplex. They are the first patented the means for hair restoration (plexes and Bonder). But today the means with maleic acid used other brands, which Olaplex lawyers running around and are suing about copyright :-))
The above described the essence of restorative hair treatment. And what is the essence of nutrients for hair treatments? Yes, actually, just to moisten the cuticle, smooth it and disguise the damage. Nothing more. As such, the utility of hair there, we just get the visual effect in the form of shiny and silky hair.
Whether it is a mask, serum or oil - all this only to achieve beautiful hair visual effect. But the very structure of the hair, they do not recover, a cosmetic effect in the form of smooth cuticles.
But when it comes to aggressive staining agents or chemical perms, here remember the maleic acid. If you do not want to get dry after dyeing, thin hair with split ends, and where the paint will stay for long - be sure to make the replacement hair procedure.
Put a "thumbs up" if you want more of these interesting materials on the hair, alopecia, and overall self-care!
