Capillary sealing: know the pros and cons of the treatment that closes the structure of the threads

It is a treatment created in Brazil based on keratin, which has the function of closing the cuticles of the wire (that is, it seals the structure), when they are damaged by chemical processes, such as smoothing and tincture. The sealing regains the health of the hair bringing more discipline, hydration, strength and shine.

However, often treatments with the name of sealing can actually be a progressive brush. This occurs when the product contains in its formulation, in addition to keratin, formalin. In these cases, this procedure also smoothes the thread. The problem is that this compound can only be present in concentrations of 0.2% in the products, otherwise it can cause several side effects, and usually in this type of concentration it does not have the desired effect.

If the sealing is intended to smoothing, but containing alternative products for smoothing, such as ammonium thioglycolate and formaldehyde-like substances, but which cause much less damage to the hair and health, there are no problems, but it still becomes smoothing.

Among the damages caused by formaldehyde to health we may list burns, scaling of the scalp, hair loss, burning eyes, shortness of breath, coughing, headache, nausea, vomiting, fainting. However, some products may still have formaldehyde in their formulation. It is easy to see this when the product releases smoke, since this product has a characteristic smell. But, in order not to be taken by surprise at the time, it is best to ask to see if it is written on the packaging that it contains formaldehyde or polyform.

Sealing indications

Sealing capillary is indicated for people who have damaged hair and open cuticles, causing the loss of nutrients in the yarn.

How is capillary sealing

Sealing usually done with shampoo, conditioner and ampoules of same line. The hair is washed with the first two products and then dried and has its ampoules applied. Then, it takes a heat source for these products to work and to close the wires, usually the wick, which is passed in each wick several times.

When the procedure also intends to smooth, the ironing process helps to rearrange the sulfur chains of the threads, making them smooth again.

Sessions

The number of times the sealing for cuticle closure should be made varies according to the degree of yarn damage. The number of sessions will depend on the level of sensitization of the wires, and the periodicity will be determined by the professional who did the analysis. In general, it can be done every two or three months.

The sealing with smoothing is done in a single session and repeated as the effect passes, like the progressive brush.

Care before capillary sealing

No special precautions are required prior to capillary sealing.

Care after capillary sealing

If hair treated with capillary sealing without smoothing, the only care required is when it is sealed. If the sealing is intended to also smooth the threads, it is best to avoid using deep cleaning shampoos or anti- waste, since they shorten the duration of the effect of this procedure.

When washing your hair, use a generous amount of conditioner to reduce the brittleness of the hair. Moisturize often and avoid discoloration or dyeing hair at short intervals after the procedure, as this may potentiate damage. If hair becomes brittle and has frizz, stop doing the procedure and wait for the growth of new yarns that will replace damaged hair.

Sealing Contraindications

If your hair is highly sensitized to the point of not being able to undergo

If sealing is accompanied by straightening, people with sensitive scalp and very oily hair should not do so because they cause even more tenderness and oiliness on the leather. In addition, people with virgin hair are not totally contraindicated, but usually do not get the best results when doing this technique.

Avoid this procedure if your hair is too curly, as it will not work for hair straightening and straightening.

Pregnant can do?

Common sealing, with keratin alone, can be done in gestation, but ideally it should be after the third month. However, since there is always a chance that the product will have some formol or other smoothing chemicals, the ideal thing is for the pregnant woman to photograph the ingredients of the product and take it for the analysis of a reliable dermatologist who will be able to guide her if the product is or is not safe. This action is also valid for non-pregnant women as well.

Sealing hazards

The heat of the plaque should suit the level of sensitivity of the wires. Excessive heat on a heavily damaged hair can sensitize you further. In addition, excess keratin may cause hardening of the threads, so it is important that the procedure is done by a trusted professional.

If there is a formaldehyde above the concentration recommended by Anvisa, ie 0.2% of the product, can cause various health problems, such as burns, scaling of the scalp, hair loss, burning eyes, shortness of breath, coughing, headache, nausea, vomiting, fainting, etc. they may make a mistake at the time of making the chap. These devices can reach a temperature of 230 degrees Celsius, while the hair can withstand a maximum of 200 ºC. When using the iron at maximum temperature, the hair fibers are burned and the hair is damaged, but this is only noticed after a while, when the progressive product begins to leave the threads.

Before and after the capillary sealing

Keratin-only sealing can improve the appearance of some types of hair and even make them more aligned and disciplined, giving the impression that it smoothes. In addition, it will bring an intense glow to the hair, which is more nourished and healthy.

Straightening sealing will have the same results as a progressive brush, hair will be smooth and without volume, with a reduction in the frizz effect of the wires . Sometimes, however, hair can look plump, as volume and waves are completely removed. This is because the progressive brush leaves a residue, which can accumulate on the strands, making them increasingly smooth.

Think about the set of riding clothes (the fair with the ample) or the sensuality of ice-skating (shiny body and transparencies). Skier coats are also mixed with sober modeling pieces.
