They are easy to dry, style and create original hairstyles.
- European hair … Curls of this type can be imported not only from Europe, but also from India or Latin America. Their pricing policy is much higher than the Asian ones, which cannot be said about the quality. The process of creating strands for extension consists in pre-acidizing the hair, dyeing and processing with silicone. In this case, the top flaky layer can be completely or partially removed. This hair is suitable for women with their coarse, thick and voluminous hair.

Features of hot hair extension
The essence of the process is to use a pre-heated adhesive (keratin or resin), which is applied to the hair strands and fixed at the roots using a special gun or thermal tongs. A special capsule acts as a retainer. It is completely invisible, but it is able to securely hold a strand of hair. The hot hair extension method has many benefits. The main ones are the rapid increase in length and the creation of volume and density.
Advantages and Disadvantages of Capsule Hair Extensions
Recently, among professional stylists, capsule extensions are gaining particular popularity, which several times improves the aesthetic characteristics of hair. The technology of this process consists in attaching donor strands to natural hair using a melted keratin capsule. The number of capsules depends on the desired effect and the number of curls attached.
The main advantage of capsule extension is the ability to create original and complex hairstyles. This is because thin strands are used in the process, and the fixing capsules are almost invisible. Curls can be straightened with an iron, permed, done hairstyles, twisted on curlers and papillotes, dyed and toned.
You can extend hair using the capsule hot method on bangs, parting, temples. At the same time, the extended strands are not combed out and are worn for a long period. With such hair, you can visit the sauna, solarium without restrictions. The capsules will not deteriorate when exposed to high temperatures.
Also, hair extended on capsules is quite unpretentious in care. To maintain the natural beauty of the curls, they can be washed frequently, combed and even dried with a hairdryer. In addition, the capsule extension allows not only to increase the length of the hair, but also to significantly add in volume. After all, with capsules, strands can be attached all over the head in the necessary places, and not in one line.
Despite a number of advantages, hot hair extension has its disadvantages:
- The capsules can sometimes slide off.
- If the capsules are large, they will cause inconvenience when lying down for several days after building up.
- In girls with too oily scalp, the capsules will gradually collapse under the influence of fat.
- Do not apply balms and masks directly to the capsules themselves, this can damage them.
It is worth noting the contraindications of this method of building. It is not suitable for girls with thin hair or for those whose hair falls out profusely.
Hot hair extension techniques for capsules
Hair extension, however, like any other cosmetic procedure, requires preparation. Therefore, before proceeding with the lengthening of the strands, you must thoroughly wash and dry your hair. When shampooing, do not use additional hair care products such as conditioners, rinses or masks. It is recommended to be patient, because the procedure takes about 3 hours.
Hot build-up is performed using two main technologies:
- Italian hair extension technology … The safest and safest hot procedure. For extension, strands with keratin resin already applied are used. They are consistently attached to natural hair using thermal double-sided tongs, which are adjusted to a certain temperature. At the junction, an inconspicuous capsule of transparent color is formed, which immediately takes on the shade of the hair. Capsules of Italian technology are so durable that they can withstand perm, hair coloring, bath and water procedures. Also, donor hair on capsules is not combed out during wearing and does not have a negative effect on natural hair. If it is necessary to remove hair extensions, a gel-like agent is used that instantly soaks the capsules. Duration of wearing hair extensions with Italian technology is from 4 to 6 months.
- English hair extension technology … Just like the previous technique, it refers to a number of hot procedures. Its essence lies in building curls using a refractory resin based on organic substances. Capsules for this process are formed under a certain temperature and squeezed out with a special gun. English technology, unlike Italian technology, is less practical. It's all about the capsules for the strands, which are several times larger and more noticeable. The duration of the effect of hair extensions is no more than 3 months.
Features of cold hair extension
The technology of this method excludes the use of thermal heating of a special adhesive. Strands are securely attached to natural hair and do not fall out when combing. Cold-extended curls can be washed using conditioners, balms and masks. They are absolutely harmless to such compounds. As a rule, cold extensions involve a tape method of attaching the hair.
Pros and cons of tape hair extension
The tape type of fastening curls refers to the cold method of hair extension. For its implementation, a special adhesive tape and strands of donor hair are used. Tape build-up is the fastest way, because it does not require the use of special thermal equipment. The adhesive composition is absolutely safe for hair and scalp and, if necessary, can be easily and completely removed using a special solution.
The main advantage of tape build-up is the use of non-toxic substances and the absence of high temperatures. The duration of the effect of this method depends on the correct hair care. On average, it is about one year.
With tape-extended hair, there are no restrictions on actions. With curls, you can visit the solarium, swimming pool, sauna, without fear that the strands will fall off.
Also, cold build-up is more gentle than hot. Hair lends itself to minimal negative impact during the extension procedure. The capsule, which is made up of surgical glue, is as strong as the keratin one used for hot build-up.
A significant drawback of this method is the visibility of the lines when creating hairstyles. There may also be such disadvantages:
- With improper cold extension, donor hair may begin to fall out. The same can happen with your own curls.
- If the capsules are not positioned correctly, mats can constantly form.
- Your own hair can react negatively to the chemical attack of the adhesive.
However, all the disadvantages of this method are more related to the peculiarities of improper hair extension. If the procedure was carried out correctly, then problems, as a rule, do not arise.
Hair extension technologies using bands
Cold hair extension can also be carried out using various technologies:
- Spanish hair extension technology … It is a cold process. An adhesive composition is used for it, which includes glue, an activator and a dye: for light hair - white, and for dark hair - black. A small capsule is applied to the connection of the donor strand, which provides strong hold with natural hair. The term for wearing hair extensions using the Spanish technique is about 4 months. After the expiration of the term, the curls require correction or removal, which is carried out using a special solvent.
- Japanese hair extension technology … Refers to the cold method. This technique uses special metal beads, clips or clips. Donor strands are fixed with accessories at the hair roots. Using a small hook, the curls are threaded into clips or a clip and fastened with special pliers. Glue is not used in this technique, and the fixators are selected in accordance with the hair color. Correction is recommended 2 months after building.
Types of hair extensions using braids
In addition to the widespread cold and hot types of hair extensions, braid hair extensions have recently gained popularity. This method was specially developed to protect natural hair as much as possible from the negative effects of chemicals and hot temperatures.
Advantages and disadvantages of braiding hair extensions
Hair, extended in this way, is held quite tightly, and the attachment points of the curls are practically invisible. With this method, a very thin pigtail is woven across the back of the head. After it is ready, strands are attached to it in the form of a weft. The latter is hair, processed and connected at the base in such a way that it looks like a narrow strip. One tress is sewn to each braid.
Usually, the correction should be done once every couple of months. In this case, the tress is removed, and the pigtail needs to be woven closer to the scalp. After that, the weft is sewn back on. You can use them repeatedly.
It is possible to extend hair in this way regardless of its structure, color, volume, thickness. Pigtails braided at the base of the hair do not cause any inconvenience. This extension method is completely harmless. There is no thermal or chemical effect on the hair. And the procedure is carried out much faster than all other types of extension.
As for the disadvantages of this hair extension method, it can only be noted that the use of braids limits the use of certain types of hairstyles. So, you have to give up high hairstyles, even parting.
Also, building on tresses is referred to as short-lived methods. Depending on the intensity of hair growth, re-extension will have to be done in 2-3 months.
Hair Extension Methods Using Braids
Basically, the method of hair extension on braids is made using two technologies:
- Brazilian build-up … This is the newest and most gentle way. The procedure involves braiding false strands along with your own hair. In this case, one of the three strands is your own hair, two are artificial. The braid is braided up to 1/8 of the total length of the hair.
- African build-up … This technology uses sewn hair wefts. In the process, the master weaves an African braid at the back of the head and sews wefts to it.
