Capillary sealing: see how it is made, products and prices

Maintaining beautiful, strong and healthy hair is not easy. For this reason, the market constantly launches capillary procedures that promise miracles.

It is important to be attentive to the products that are offered, what types of hair are indicated and what ingredients they contain in their formulation.

Not every procedure is suitable for all types of hair, so there are so many options and one of them is capillary sealing, a procedure that aims to hydrate and restore damaged hair.

Do you know capillary sealing? Let’s find out more about it together …


What is capillary sealing?

Capillary sealing, also known as thermal sealing, shielding or capillary plastic, is a procedure made with a keratin-based product, in order to seal the cuticles of the hair strands, to protect the hair from external damage.

Most capillary damage occurs in the capillary cuticle, which is the layer most exposed to damage. They can be of external means (sun, rain, pollution, etc.), mechanical action (combing, tying, etc.) and chemical damage (relaxation, permanent, coloring, reflections, etc.).

The hair strands are formed by three parts in its extension: the cuticle, the cortex and the medulla.

The cuticle is the outer part of the hair and represents 88% of the hair fiber. It is responsible for regulating the entry and exit of water and protect the inner layers of the wire.

The sealing is indicated for people adept at chemical procedures (such as discoloration, dyeing and straightening), for those who frequently use a hairdryer, flat iron, babyliss, for people dissatisfied with the volume of the hair, lack of shine and split ends.

The sealing effect usually lasts for up to 3 months, this will depend on the amount of times you wash your hair.

It is important to maintain a hair care routine after sealing, hydrating or adopting a capillary schedule, which consists of moisturizing, nourishing and rebuilding the strands.

What is the difference between sealing and progressive?

The main difference between sealing and progressive is its purpose. The sealing is made based on keratin, in order to nourish and repair damaged hair. The progressive brush, on the other hand, smooths the hair, using chemical products that attack the hair and leave it dry.

In the sealing, the products used have in their formulation keratin, vegetable oils and products that deeply moisturize the hair, providing a healthy and disciplined hair.

The progressive one normally contains formaldehyde, a chemical agent allowed by the National Health Surveillance Agency (ANVISA) only when used in the maximum amount of 0.2% of the formulation.

This determination guarantees the safety of the person performing the procedure and also of the professional.

For this reason, sealing ends up being a better option for those who want to tame their hair. But it is worth remembering that it does not smooth, it only moisturizes and disciplines the hair.

What is it for?

The purpose of the sealing is to replace the keratin of the threads, providing hydration and repair to fragile hair. Thus, the technique ends up restoring health, resistance and shine to the wires.

This is because most of the hair is made up of keratin, a protein that the human body produces and can be found in hair, skin and nails.

The keratin present in the seal makes a protective barrier in the cuticle of the hair, retaining water and nutrients in the inner layers of the hair, which guarantees a hydrated and soft hair.

Check out the benefits of capillary sealing below:

  • It has antifrizz effect;
  • Reduces hair volume;
  • Provides shine and softness;
  • Strengthens the threads;
  • Eliminates split ends.

To maintain the beauty of the hair with the sealing it is recommended to moisturize weekly and avoid washing in hot water.

Sealing straightens hair?

The main purpose of sealing is to treat and discipline the threads, making them more silky, aligned and reducing frizz and volume. For those who want to straighten their hair, the most recommended is the progressive brush, as it contains chemical agents in its formula that change the structure of the strands, leaving them really smooth.

So it is important to keep an eye on the products used for sealing. If you are going to do the procedure in a salon, ask to look at the formulation of the products.

If in addition to keratin formol, ammonium thioglycolate, etalonamine or similar are present in the formula, stay tuned. These substances can straighten your hair, but there is a risk of damaging it.

Homemade capillary sealing: step by step

Sealing, as it is a simpler process, generally does not cause damage to health and can be done at home. However, when experiencing any allergic reaction, it is recommended to discontinue use and consult a doctor.

Check out a simple walkthrough:

  1. Wash your hair with a deep cleansing shampoo (anti-residue), to open the cuticles of the strands;

  4. Dry your hair with a hairdryer. Then, with the help of a board heated to 200 ºC (recommended temperature), plank several times strand by strand of hair (6 to 10 times each). Smoke may come out of the hair during the procedure. The ideal is to do the sealing in an open or airy place;
  5. Let the product act for 20 to 30 minutes;
  6. Rinse well with warm or cold water to remove the entire mask from the wires;
  7. Apply a conditioner to close the hair cuticles;
  8. Rinse your hair again;
