Because hair repair, has always been a very difficult problem to solve. Hair and skin are not the same, grow out is dead cells, can not be resurrected, there is no metabolism.
Like a broken wall in your home, it can only be fixed temporarily by physical repair, or - cut your hair and let it grow back.
Silicone oil, on the other hand, is one of the most outstanding restorers.
Although the hair is very fine, but the structure is still complex, still can divide into epidermis layer (wool scale), coriaceous layer and medullary layer 3, in the light of the hair repair protect, concentrate in epidermis layer commonly.
The epidermis is covered with layers of fish-like scales, which are so fragile that they can cause permanent damage if you scratch, comb or dye your hair.
And after the hair is damaged outside, the coriaceous layer that can let inner layer further is damaged, the final hair leaves you with one and go.
Since all hair restoration is "treating the symptoms, not the root cause", then we have to choose a strong player.
This is where silicone oil performs its "artificial Saiyan" properties: it has low surface tension, spreads easily, and is extremely hydrophobic.
So if you put it on your hair, you can create a very thin (a few nanometers thick), but a very uniform and shiny film that stops the outside world from damaging your hair and directly extends the life of your hair.
Straight men dream of long hair to reach the waist, estimated that it will take many years to grow out, such a large amount of hair care, the difficulty is not straight men can imagine, if separated from silicone oil, can be really difficult to do it!
