C-bend is one of the most important characteristics. It is thanks to him that artificial nails have strength and beauty. The volumetric shape of the artificial nail is created by two arches: the upper longitudinal one, which runs from the cuticle to the free edge of the nail, and the transverse one, connecting the lateral sides at their very bottom, in the corners of “smiles”.
The intersection of these arches is the highest point of the nail, which is located in the stress zone. Because the “smile” line of a natural nail has a certain curvature, the highest point never falls on it. The height of the highest point is the height of the C-bend. Summarizing all of the above, it can be argued that the C-bend is created by the highest point, the upper and lower arches of the nail. Once again, let’s dwell on the location and height of the highest point of the nail.
These parameters are very important when modeling because they affect strength. The highest point of the nail can be seen as its center of gravity. Let’s go back to construction and imagine a skyscraper with an offset center of gravity.
According to all the laws of physics, this building is a fragile structure doomed to destruction. Likewise, nails. Disregarding physics icons dramatically reduces their lifespan. Very often, when making artificial nails, masters make them more durable “by increasing the thickness of the free edge. Thus, they shift the highest point closer to the end of the nail, disrupting its architecture, which naturally leads to breaking off (Figure – B). and displacement towards the cuticle (Figure – B) In this case, the problem is aggravated by the difficulties in processing the border between the natural nail and the coating. Result: a nail cut down near the cuticle, poor cleaning of the border, flaking of the coating. As a rule, the position of the highest point at the intersection of two arches (Figure – A) coincides with the middle of the nail with a moderate length of the free edge (not exceeding the length of the nail body). With a sufficiently large increase in the length of the nails or, conversely, their slight lengthening, the highest point will also be located in the middle of the nail, but not coincide with the intersection of the arches. Thus, in the first case, it moves to the tip (Figure – D), and in the second – to the cuticle (Figure – E). With a sufficiently large increase in the length of the nails or, conversely, their slight lengthening, the highest point will also be located in the middle of the nail, but not coincide with the intersection of the arches. Thus, in the first case, it moves to the tip (Figure – D), and in the second – to the cuticle (Figure – E). With a sufficiently large increase in the length of the nails or, conversely, their slight lengthening, the highest point will also be located in the middle of the nail, but not coincide with the intersection of the arches. Thus, in the first case, it moves to the tip (Figure – D), and in the second – to the cuticle (Figure – E).
Now let’s talk about the height of the C-bend. Its excessive value indicates a large amount of modeling material on the nail. From this, artificial nails, oddly enough, do not become stronger. The opposite occurs. Let’s remember that they are natural *! nails, among other things, have a protective function. They are shock absorbers, damping (smoothing) various influences, including shocks. In other words, natural nails need to be flexible to resist pressure. But artificial ones should have exactly the same properties. They should be doubly flexible, protecting both fingers and natural nails. A large mass of modeling material does not contribute to their flexibility. Yes, nails become strong but not flexible. They are more fragile than thin nails made from the same material.
But this is only one side of the issue. The other is even sadder. With a thick coating, the natural nail becomes thinner and, as a last resort, peels off the nail bed. The nail bed is a layer of the epidermis that produces cells (onycholysis), due to which the thickness of the nail grows. With strong constant pressure on the nail bed (a thick layer of modeling material), the growth of onycholysis slows down. This leads to thinning or depletion of the natural nail and even flaking from the bed. With a low C-bend height, the nails look flat, their strength is low because the thickness of the modeling layer in the stress zone is small. Therefore, it is necessary to maintain a balance in which the height of the C-bend is proportional to the length and width of the nail body.
Checking the correctness of construction of the C-bend
Artificial nails will be considered perfect only if the C-bend is the same on all nails. Moreover, the skill of professional consists in creating completely identical arches. It was already noted earlier that the nails on the hands of the same person are completely different: one is flatter, the other generally grows downward. The art of modeling is about making them look the same. How can you check the quality of your work? There are three ways:
1. Position the nail so that you can look at the nail, ie. end in front of you. Put a file or your own finger on top of it and look at its tip. The hairline should be equally thin on all 10 nails. It should not have dips and bulges.
2. In the same position, but removing the file, you can check the size and identity of the position of the C-bends on all nails.
3. Now let’s look at the nails from the client’s side. Place the client’s finger so that the highest point of the nail is at eye level. If at the same time the tip of the nail is not visible, then the C-bend is sufficient in size. If the free edge of the nail is clearly visible, then the height of the highest point is insufficient.
