Sealing appears as a great treatment option for some hair types, solving problems and giving your hair more health.
Also known as hair shielding, sealing is a type of keratin-based treatment. Which, in turn, has the function of closing the hair cuticles, that is, the structure. It is used when they are damaged by chemical processes. Sealing restores hair health, with discipline, hydration, resistance and shine.
In many cases, sealing is actually progressive brushing. This occurs in cases where the product contains formaldehyde in its formulation, in addition to keratin. In this situation, the thread is also straightened. However, the compound may be present in concentrations of 0.2% in products. Otherwise, it may cause several side effects. Furthermore, it normally does not bring the desired effect in this type of concentration.
If the sealing is to straighten, and there are alternative straightening products, such as ammonium thioglycolate and ethalonamine, which are similar to formaldehyde, but do not cause as much damage to health, but still, it is a type of straightening.
One of the damages that formaldehyde causes is burning, peeling of the scalp, hair loss, burning eyes, shortness of breath, coughing, headache, vomiting, nausea and fainting. However, in some products, formaldehyde is still present. When the product smokes, it is easy to notice. The ideal is to ask to check the packaging and look for the word formaldehyde or polyformol.
What is sealing for?
It is recommended for damaged hair with open cuticles, caused by chemical procedures, requiring intense nutrient replacement. Accordingly, this sealing effect makes the strands more disciplined and have less volume. Resulting in hair recovery from the inside out. In addition, there is a reduction in frizz.
How to make
It is normally made with shampoo, conditioner and ampoules, all from the same line. The hair is then washed with shampoo and conditioner, dried and the ampoules applied.
Then, a heat source is needed for the products to work correctly, closing the strands, normally the straightener, is the accessory used on the strands.
When there is also the intention of straightening, the straightening process helps to reorganize the sulfur chains in the hair. Which causes them to become smooth once again.
Sessions
The number of times sealing is done so that the cuticles close will vary according to the degree of damage to the hair. Therefore, the number of sessions depends on the level of sensitization of the hair, and the period to be applied will be determined by the professional carrying out the analysis. Generally, it can be done every two or three months.
The one that has straightening is carried out in one session and only done again, as the effect wears off. The main difference between them is that hair sealing is aimed at treatment, whereas progressive treatment straightens the hair strands.
As it is a complex procedure, it requires attention. Exactly for this reason, it must be done by trusted hairdressers and can never be done at home or in any other untrusted location. No special care is required before performing hair sealing.
Care after sealing
If the hair that received the treatment has not been straightened, it is only necessary to take care of it if there is a lot of damage, that is, do not dye or straighten it. If the seal has also been smoothed, it is recommended to avoid using deep cleaning or anti-residue shampoos, as they make the effect shorter in duration.
When washing your hair, use plenty of conditioner to reduce the fragility of your hair. Moisturize frequently and avoid bleaching or dyeing your hair in short intervals after carrying out the procedure, which can eventually increase damage.
If your hair becomes brittle and frizzy, do not do the procedure again and wait for new strands to grow and replace the damaged hair.
Contraindications
If the hair is very sensitive and cannot receive heat sources, the procedure is not recommended. If the seal has smoothing. Those with sensitive scalps and oily hair should not do this. This can cause even greater sensitivity and oiliness in the leather.
People with virgin hair are not completely indicted, but they also do not have the best results when using this technique. Avoid procedures if your hair is very frizzy, as it will not work to reorganize and straighten the strands.
In the case of pregnancy, sealing with only keratin is permitted, but recommended after the third month. But, as there is always a chance that at least one product will contain some amount of formaldehyde or straightening chemicals, it is ideal for pregnant women to see the ingredients and take them to a confident dermatologist for analysis, as they will be able to advise on the product. This also applies to non-pregnant women.
Does sealing ruin your hair?
The heat used in the straightener must be equal to the sensitivity level of the hair. Excess heat on damaged hair can make it even more sensitive. Therefore, excess keratin causes the hair to become stiff, so it is important to have it carried out by a professional.
If the concentration of formaldehyde used is greater than 0.2%, it can cause several health problems, such as burns, scalp peeling, among others.
Some professionals may make mistakes when performing a straightener. It can reach temperatures greater than 230 degrees Celsius, however, the hair can withstand a maximum of 200 degrees. Soon, the hair fibers are burned and the hair is damaged. However, it is noticed after a period, when the progressive leaves the hair.
Before and after
Sealing improves the appearance of some hair types and makes them more aligned and disciplined, giving the impression of straightening. It also brings intense shine to the hair, as it is more nourished and healthier.
Sealing with straightening has the same result as a progressive one, where the hair is smooth and has no volume, having an effect of reducing frizz in the strands. However, sometimes, the hair can look flat, as the volume and waves are removed.
This happens because the progressive brush leaves residue, which accumulates on the hair, making it increasingly smooth. Helps keep hair healthy after chemicals or daily damage, such as using a hairdryer or straightener.
Curiosities
Firstly, sealing is not intended to straighten hair. It only guarantees improved hydration and texture of the hair, which are restored after the keratin is applied. The chemical-free sealing is highly recommended for hair that has just undergone some type of chemical treatment.
Hair sealing can break the hair if the procedure is done incorrectly. When you add too much keratin or leave it to sit in your hair for a long time, the fiber becomes harder, causing the hair to break. This procedure can only be carried out at home with the guidance of a specialized beauty professional.
How often hair sealing should be applied will depend on the condition of the hair. The effect can last for up to three months, depending on the number of times the hair is washed.
Difference between progressive, sealing and hair botox

Sealing
For voluminous, damaged, brittle, frizzy hair or in need of intensive treatment. The function here is to seal cuticles, eliminating porous, dry and dull aspects.
Hair Botox
It replaces the hair mass that was lost, making the hair more resistant, hydrated and aligned. It achieves a semi-smooth effect, that is, it replaces the reduced volume mass. Before carrying out this type of treatment, talk to a professional. Check whether the product will only act as a treatment, replacing only the hair mass or whether it will be a volume reduction treatment.
