Sericin is a protein found in silk fiber and has been widely used in hair treatments due to its various benefits.
For those who are always looking for new things in hair treatments, you may have already heard about sericin. Sericin is an active ingredient that has been widely used in hair products due to its repairing and moisturizing action. Thus, like its derivative, seriseal.
As we know, keeping hair silky and shiny is not an easy task. Even more so for those who are used to using chemical treatments, such as dyeing and straightening. In this case, special treatment is needed to protect the hair from external aggressions.
Therefore, sericin becomes a great option for treating hair. Bringing several benefits, such as hydration, protection and reconstruction. It is no coincidence that this active ingredient is even found in formaldehyde-free progressive brush formulas, as it contributes to straightening and reducing volume.
Therefore, today we will learn more about this powerful active ingredient, and all its benefits for the hair.
To sericin
Sericin is a protein that forms silk fiber, comprising around 30% of its entire composition. It surrounds silk fibroin with several adhesive layers, which contributes to the formation of silkworm cocoons.
Made up of several amino acids, such as serine, aspartic acid, glycine and threonine, sericin has several beneficial properties for the cosmetics industry. Among them: strong moisturizing action, resulting from the large amount of serine, anti-wrinkle action, antioxidant and antibacterial effect, sun protection, moisture absorption, among others.
Furthermore, sericin is very compatible with other important proteins, such as keratin, for example. Thus, when bonding with keratin, sericin ends up forming a natural film that protects the hair, like a kind of protective barrier.
Furthermore, this bond between sericin and keratin ends up sealing the damaged hair cuticles. In this way, it helps to condition the hair, improving its appearance, leaving the hair smoother, aligned and shiny.
applications
Therefore, sericin has been widely used as a differential in straightening treatments, such as formaldehyde-free progressive brushes. These treatments use keratin, silicone and sericin to reduce volume while promoting deep hydration in the hair.
In addition to hair treatments, sericin can also be used in cosmetic products for the skin and nails, being very present in the composition of soaps, makeup and cosmetics in general.
For the skin, sericin helps maintain hydration, in addition to having an antioxidant and antibacterial effect, which protects the skin from external aggressions, including the effects of sunlight.
Benefits of sericin for hair
Therefore, sericin is an active ingredient that promotes a series of benefits for the hair, the main ones of which include:
- Restores the shine and softness of the hair;
- Seals the hair cuticles,
- Conditioning action;
- Reduces volume and frizz;
- Repairs damaged scales;
- Increases the elasticity of the hair;
- Smooth effect;
- Keeps the wires aligned;
- Returns the mass lost to natural and chemical aggressions.
Seriseal
Seriseal is an active result of nanotechnology, composed of reduced sericin particles. These cationic sericin particles can also be used in cosmetic products, and have practically the same functions, although some are even more effective than sericin itself.
Seriseal is best suited for specific products for hair recovery, such as conditioners, but it can also be used in leave ins, dyes, finishers, styling creams and straighteners. This is because this active ingredient offers greater coverage of the hair, without altering the structure of the hair or increasing its natural oiliness. Furthermore, it is very effective in treating bleached, dry hair and split ends.
The difference between seriseal and sericin is the action on the hair surface. While sericin has adhesive properties on hair, seriseal is more effective in sealing action, especially as it is more concentrated.
However, both active ingredients are very beneficial for the hair. Both have a conditioning effect, promote shine and softness, seal and restore the healthy appearance of the hair.
