What is DHI hair transplant? | Dr de Freitas

Hair loss is a problem that affects many people worldwide. Over the years, various hair transplant techniques and treatments for combating hair loss and restoring hair density have been developed. One of the most innovative and effective methods is Direct Hair Implantation (DHI), an increasingly popular choice for those seeking hair loss solutions. In this article, we will explore in depth what the DHI technique is, what it involves, how it compares to the FUE technique, the step-by-step process of the DHI technique, and who the ideal candidates are for this cutting-edge hair treatment.

What is the DHI Technique and How Does It Work?

The DHI technique is an advanced form of hair transplantation that has become a preferred option for many people looking to naturally and effectively restore their hair.

This technique is based on the premise of extracting hair follicles from the donor area and transplanting them directly into the recipient area, all in a single session, without the need to pre-channel the recipient area.

The main distinctive feature of the DHI technique is the use of a special pen called the Choi Implanter Pen. This device allows trichology specialists to implant hair follicles one by one in the recipient area, ensuring a high rate of survival of the transplanted follicles.

The DHI technique is considered less invasive compared to other hair transplant techniques and produces natural and permanent results.

Which is Better, DHI or FUE Technique?

To determine which of the two techniques, DHI or FUE (Follicular Unit Extraction), is the best choice, it's important to consider several factors, including the patient's needs and expectations, the desired quality of results, and the evaluation of a hair transplant specialist. Both techniques have their advantages and disadvantages.

  • The DHI technique stands out for its precision and ability to implant hair follicles directly into the recipient area without the need for prior incisions. This minimizes the time hair follicles spend outside the body, which, in turn, increases the graft survival rate. The DHI technique is ideal for those who desire immediate and natural results.
  • The FUE technique, on the other hand, involves extracting hair follicles from the donor area using a special punch and then transplanting them into the recipient area. Although this technique is effective and less invasive than traditional methods, it may require slightly longer recovery compared to DHI but still offers very good results.

The choice between DHI and FUE ultimately depends on the individual patient's preferences and needs, as well as the evaluation of a trichology specialist.

Some patients may be ideal candidates for the DHI technique due to its ability to provide immediate results and faster recovery, while others may opt for FUE if they prefer a less invasive approach.

Comparison of DHI Technique and FUE Technique

In the quest for effective solutions to combat hair loss and restore hair density, two techniques stand out: Direct Hair Implantation (DHI) and Follicular Unit Extraction (FUE). Both offer remarkable results but differ in their approaches and advantages.

Step DHI Technique FUE Technique
Extraction of Hair Follicles The Choi Implanter Pen is used to extract and transplant hair follicles directly into the recipient area. A special punch is used to extract hair follicles from the donor area, followed by transplantation.
Creation of Channels in the Recipient Area No need to create prior channels as hair follicles are implanted directly. Requires the creation of small channels in the recipient area before implanting the hair follicles.
Time Hair Follicles Spend Outside the Body Minimal, increasing the graft survival rate. Hair follicles may spend more time outside the body, which could affect their survival rate.
Immediate Results Offers virtually instant results. Results may take a bit longer to become visible.
Recovery Involves a faster recovery compared to FUE. Recovery may be slightly longer in FUE.
Scarring Scars are minimal and hardly visible. Scars are small but may be visible in some cases.
Suitability for Natural Results Provides natural and permanent results. Offers natural results, but the DHI technique can achieve better integration with existing hair.

Step-by-Step Process of the DHI Technique

The treatment with the DHI technique is a highly specialized procedure that requires experience and skill from the medical team. Below are the key steps in performing a hair transplant using the DHI method:

  1. Patient Evaluation: The process begins with a consultation at a specialized hair clinic, where a trichologist or hair transplant surgeon will assess the patient to determine if they are a suitable candidate for the DHI technique. Expectations will be discussed, and a personalized treatment plan will be developed.
  2. Extraction of Hair Follicles: In the next stage, hair follicles are carefully extracted from the donor area, typically located at the back or side of the head. This extraction is done using specialized equipment to minimize any damage to the follicles.
  3. Sorting of Hair Follicles: Once the hair follicles are extracted, they are carefully sorted according to their quality and prepared for transplantation.
  4. Creation of Channels in the Recipient Area: Unlike other techniques, DHI does not require the prior creation of channels in the recipient area. Hair follicles are implanted directly into the skin using the Choi Implanter Pen. This minimizes the time that hair follicles spend outside the body, which is crucial for their survival.
  5. Implantation of Hair Follicles: Hair follicles are implanted one by one in the recipient area following a predefined design and pattern to ensure a natural result.
  6. Closure of Donor Areas: After completing the transplant, the donor areas are closed, resulting in very small and barely visible scars.
  7. Postoperative Care: The patient will receive detailed instructions on how to properly care for the transplanted area and promote successful recovery. Postoperative care is essential to ensure that hair follicles settle and grow healthily.

Who Can Get the DHI Technique?

The DHI technique is an excellent option for many people looking to effectively restore their hair. However, not all patients are ideal candidates.

People who can benefit from the DHI technique include:

  • Men and women with hair loss: Both men and women can undergo the DHI technique to restore hair density in thinning or balding areas.
  • Individuals with androgenetic alopecia: The DHI technique is especially effective in treating androgenetic alopecia, the most common form of hair loss in men and women.
  • People seeking immediate results: DHI offers virtually instant results, making it a popular choice for those who want a visible change in their hair appearance.
  • Individuals who prefer a faster recovery: The DHI technique typically involves a faster recovery compared to other hair transplant techniques, making it attractive for people with busy schedules.
  • Those looking for natural results: The DHI technique prides itself on providing natural and permanent results, making it suitable for those who want their transplanted hair to seamlessly blend with existing hair.

It's important to note that individual evaluation is crucial. Before undergoing any hair transplant procedure, it's essential to consult with an experienced trichologist or hair transplant surgeon. These professionals can assess the patient's suitability for the DHI technique and provide personalized recommendations.

The DHI technique is an advanced and highly effective approach to hair transplantation that has gained popularity worldwide. By offering natural and permanent results with a faster recovery, it's an attractive option for those struggling with hair loss.

If you are a candidate for the DHI technique, you can expect an effective and high-quality solution to your hair loss.
