<\/span>Dhi Method and 7 Golden Tips<\/span><\/h2>\n\nThere are some tricks that have a vital effect on success in hair transplantation with the pen technique. We have brought these tricks in written form after years of experience. We felt obliged to do this for the success of this technique for those who want to have hair transplantation. We found it appropriate to collect these tricks under 7 main headings. Let’s take a brief look at them now.<\/p>\n\n
1- Diameter of Needle Tips<\/p>\n\n
All brands have tips with diameters between 0.6 mm and 1.8 mm on the market. We use 0.6, 0.8 and 1 mm tips in the dhi method. We do not believe that tips larger than 1 mm will contribute to sufficient density and natural appearance in the dhi method. If we list the usage of these needle diameters,<\/p>\n\n
\n0.6 mm: Generally used for eyebrow transplantation and single grafts on very fine hair.<\/li>\n\n\n\n 0.8 mm: Used for 1 and 2 hair follicles.<\/li>\n\n\n\n 1 mm: We use it for 2-3-4 multiple grafts.<\/li>\n<\/ul>\n\nThe diameters of the needle tip may vary depending on the manufacturing company. There are green, red, blue and pink colors on the top of the pens. These colors make it easier for us to distinguish between diameters.<\/p>\n\n
Below you can see examples of sharp-tipped hair transplantation pens available in our country. The diameters of the tips are 0.6, 0.8 and 1 mm.<\/p>\n\nSuppliers produce tips up to 1.8 mm. In our opinion, tips wider than 1 mm are not suitable for the FUE method.<\/p>\n\n
With an average choi pen, 700-1000 grafts can be transplanted. This number generally varies from person to person. The elasticity of the skin is important here. If the pen causes excessive rooting when inserted during transplantation, the tip should be changed.<\/p>\n\n
2- Width of Implanter Pen Diameters<\/p>\n\n
In very narrow ends, there is a possibility that the hair follicles will be damaged while being placed in the implanter. In case of excessive width, there is a possibility that the placed graft will fall out before the transplantation process is completed. The slit widths vary between 0.2 mm and 0.35 mm.<\/p>\n\n
In the picture below, you can see the high-resolution magnifications of 1 mm diameter needle tips from 3 different companies. The slit width of the needle tip number 1 is wider. The gripping area of \u200b\u200bthe hair root inside the needle, called the Bevel, is wider than the others. We think this situation is advantageous in terms of graft health. Of course, it would not be right to explain these dhi pen brands here.<\/p>\n\n3- Pen Needle Length<\/p>\n\n
Depth control is one of the most important issues in root placement. Some implanters have depth control. First of all, the pencil length should be reviewed in advance according to the root length.<\/p>\n\n
The standard length of the pen needle is around 7 mm. This length is reduced or increased according to the hair graft length. If there is more bleeding than expected, it means the length is too much. This length should be shortened. When we reduce the 7 mm needle length to 6.5 or 6 mm, we can see that the bleeding will decrease significantly. If we shorten the length more than necessary, the grafts will not reach sufficient depth. This time, the probability of the grafts coming out will increase. Those planted at a depth greater than normal will either not come out or will cause a curly appearance.<\/p>\n\n
A mathematical proportion should be established between the needle length and the graft length. This length should be 25-30% longer than the graft length. For example;<\/p>\n\n
Graft Length: -> Needle Length:<\/p>\n\n
\nIf it is 6 mm -> Length is 8 mm (25% increase)<\/li>\n\n\n\n If it is 5 mm -> Length is 7 mm<\/li>\n\n\n\n If it is 4 mm -> Length should be 6 mm (33% increase).<\/li>\n<\/ul>\n\nIf the doctor is experienced, she can easily adjust this ratio after a few tries.<\/p>\n\n
4- Length of the Filament That Pushes the Hair Roots Under the Skin<\/p>\n\n
This wire should definitely not protrude from the tip of the teflon spiral. If this wire protrudes when pressed from the top and is visible from the outside, it means that the application is wrong. It does not touch the top of the hair roots, but directly the root. And this means damaging the hair root. This wire should definitely not be visible from the outside. It should not be too high either. It should be at the level of the teflon protector. We can easily see this when we look at the picture below.<\/p>\n\n5- Placement of the Implanter in the Skin and Depth of Entry<\/p>\n\n
This is not a problem in implanters with stoppers (depth control). In those without depth control, the needle should never be inserted into the skin until it reaches the end. It should be stopped and its entry into the skin should be stopped when it is approximately 1 mm from the skin. Otherwise, it will be inserted deeper than normal. This is a situation that is gained over time and requires experience. While the insertion process is being carried out, it is necessary to simultaneously remove the pen from the skin. As far as we know, there is no depth control in the DHI method devices available in our country. Let’s not forget that the possibility of a graft inserted deeper than necessary is low.<\/p>\n\n
The possibilities that may arise when grafts are placed too deep are as follows.<\/p>\n\n
\nFolliculitis and Cyst: Small inflammations and oil glands called cysts may form at the hair roots.<\/li>\n\n\n\n Hair growing curly<\/li>\n\n\n\n Pit-shaped marks at the roots of the hair<\/li>\n\n\n\n Increased bleeding during surgery<\/li>\n\n\n\n Decrease in hair growth percentage<\/li>\n<\/ol>\n\nAs can be seen; correct depth control in the dhi method is one of the most important stages of the operation.<\/p>\n\n
6. Direction of the Needle Tip When Placing a Graft<\/p>\n\n
According to our experience, the pen’s slit part facing down (i.e. facing the skin) increases the probability of success. In this way, while the sharp part of the needle is inserted into the skin, its angle is simultaneously made horizontal. Thus, the required depth of planting is done in a controlled manner. When inserted at a horizontal angle, full harmony is achieved with the fat tissue and capillary tissue where the hair graft will be combined. In scarred areas and vertex region, inserting the pen by turning it will be advantageous in terms of depth control.<\/p>\n\n
7. Stretching the Skin<\/p>\n\n
When the pen technique is applied, pressure will be created as a result of the insertion of the implanter pen needle. With this pressure, it is possible for other hair grafts placed to pop. In order to minimize this situation, other assistant personnel next to the doctor stretch the scalp during the transplant. The assistant personnel stretches the skin from the front, while the doctor stretches the skin from the back of the transplanted area. Stretching is even more important especially in transplants made to the front areas. In addition, the angle of entry of the grafts is reduced even more with the stretching performed. And it allows for horizontal DHI hair transplantation.<\/p>\n

<\/span>What is Choi Hair Transplant?<\/span><\/h3>\n\n\n
It is the application of hair follicles transplantation with pens called implanter pens. Hair follicles are never touched by hand. It has many advantages over other methods. It is the most preferred hair transplantation method in recent years.<\/p>\n\n<\/div>\n<\/div>\n
\n
<\/span>Who can undergo DHI Hair Transplantation?<\/span><\/h3>\n\n\n
There is no patient group that the DHI method cannot be applied to. It is the most ideal method especially for women and those who have transplants without shaving. The important thing is to apply this technique correctly.<\/p>\n\n<\/div>\n<\/div>\n
\n
<\/span>Are there any side effects of Choi hair transplantation?<\/span><\/h3>\n\n\n
This method has absolutely no harm. The transplant should be done with appropriate diameters according to the hair thickness of the person to be transplanted. On the contrary, it has many advantages over other methods.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
