DHI vs FUE Hair Transplants - Which Method Is Better?

Graft Survival Rates

One of the primary concerns in hair transplant surgery is the survival rate of the grafts post-implantation. Studies have shown that FUE generally has a higher graft survival rate compared to DHI. This increased survival rate can be attributed to several factors, including the precision of graft handling and the speed at which the follicles are implanted.

In the DHI method, while the Choi pen offers the advantage of immediate implantation, it also presents certain risks. The narrow design of the Choi pen can lead to damage to the hair follicles, particularly if they are not perfectly suited for this method. A percentage of the follicles can be compromised during the extraction and implantation process, resulting in reduced overall graft survival. This is a significant drawback when compared to FUE, where follicles are handled more delicately, thus maximizing their chances of survival.

Suitability for Hair Types

Another critical factor to consider is the suitability of these methods for different hair types. DHI is not universally compatible with all types of hair. The Choi pen’s narrow size can pose challenges when working with more curved hair follicles, which are often found in curly or afro-textured hair.

Curly hair tends to have a more intricate growth pattern, and its follicles can be C-shaped. This curvature makes them more susceptible to damage during the DHI implantation process. If the Choi pen does not accommodate the natural curvature of these follicles, it can lead to improper implantation and reduced growth potential. In contrast, FUE does not have this limitation, as the extraction and implantation processes can be adjusted to suit the specific characteristics of the hair being transplanted.

The Extraction Process: FUE vs. DHI

The extraction process in FUE involves the use of a motorized or manual punch tool to carefully remove each follicle from the donor area. This process allows for meticulous handling of each graft, ensuring minimal trauma and preserving the integrity of the follicles.

In contrast, the DHI method relies on the Choi pen for both extraction and implantation. While this may streamline the process, it introduces a higher risk of damage during both stages. The extraction process using the Choi pen can lead to increased trauma to the follicles, particularly for those with curls or kinks in their hair, further affecting survival rates.

Implantation Technique

The implantation technique also differs significantly between FUE and DHI. In FUE, the follicles are strategically placed into incisions made in the recipient area. This method allows for precise control over the angle, depth, and direction of each graft, resulting in a natural appearance. The surgeon can take the time to ensure that each follicle is positioned optimally for growth.

DHI, while offering immediate implantation, does not always allow for the same level of precision. The Choi pen may not enable the surgeon to manipulate the angle and depth as effectively as in FUE, particularly for curved or C-shaped follicles. This can lead to suboptimal placement, which further affects the overall success of the transplant.

Recovery and Aftercare

Both FUE and DHI procedures require aftercare to ensure proper healing and optimal results. However, patients often find that the recovery period following an FUE procedure is smoother due to the method’s less invasive nature. The donor area typically heals quickly, and patients can often return to their regular activities within a few days.

Cost Considerations

Another aspect to consider when comparing these two methods is the cost. While both FUE and DHI are considered premium hair transplant techniques, DHI procedures are often priced higher due to the specialized equipment used and the perceived convenience of the method. However, given the higher graft survival rates and the overall effectiveness of FUE, many patients find that they receive better value from FUE treatments, particularly when long-term results are taken into account. With our UK hair transplant costs reducing significantly over the past few years from £110,000 + down to prices starting around £2,500 FUE procedures have now moved into the realm of affodability for most patients.
