What is a DHI (CHOI Pen) Hair Transplant?

DHI Hair Transplantation means “Direct Hair Transplantation”. In this method, grafts are collected by the experts with a medical pen called CHOI, and grafts are placed with the same pen without incision or opening any channels.

DHI hair transplantation is one of the hair transplantation methods used by people who have baldness problems due to hair loss. DHI hair transplantation is a very new technique that has been used especially since 2016. Hair loss can occur in people for various reasons. Whatever the reason for the aforementioned hair loss, it has become possible to have brand new hair with DHI hair transplantation. In this way, there is a serious decrease in the waiting time for hair follicles in the external environment.

What happens during DHI (CHOI Pen) Hair Transplant?

Extraction phase


The specialized doctor extracts the grafts (hair follicles) one by one from the donor area using the Choi implanter (The graft is inserted gently within the hollow needle, which is positioned at the end of the implanter pen). Then, The follicles will be kept at a specific temperature and in a solution that enhances their development after transplantation, without separating, cutting, or generally handling the follicles.


Transplantation phase ​


The grafts are implanted directly into the empty area at an accurate angle of 40-45 degrees using the DHI Implanter without creating of holes or incisions. The graft is implanted by pressing down on the plunger of the DHI Implanter.

What can you expect during DHI (CHOI Pen) Hair Transplant

Most people take about three days off work after a DHI procedure, but the transplanted area will have crusting or scabbing and may look pink (like a sunburn) for about a week, so you may want to take that long. Recovery is fast, but it takes about 8 days for the donor zone to look fully healed.

If the full donor area was shaved, it will take about 7-10 days for the hair to grow into what looks like a buzz cut. 

Our doctor will give you specific instructions for washing and caring for your hair during recovery. Follow those instructions closely, to ensure the best result. 

Most doctors recommend waiting 48 hours before washing your hair, then being very gentle as you cleanse (no scrubbing). Instead of positioning your scalp directly under the shower head, try for less pressure, even using a cup to pour water over your head for the first week of showers.

Here’s a guide to how quickly you can return to regular activities (for best results, heed your surgeon’s advice).
After 3 days: Return to normal activities and light exercises, such as walking and light yoga. 
After 7 days: Resume moderate exercise but avoid anything that greatly elevates your heartbeat or causes you to really perspire. The scalp can be very sensitive after a transplant, and excessive sweating may irritate it and damage new hair grafts. 
After 1 -2 months: Get back to, cardio softly, running, weight lifting softly, and other strenuous activities.

When will you see results from an FUE hair transplant and how long will they last?

You should see about 50% of the transplanted hairs growing within about three months, 80% growing in eight months, and a final result in 12 to 24 months.

 After your procedure, the majority of the newly transplanted hairs will fall out within the first three to eight weeks, in a process known as anagen effluvium. Often, this happens in a wave, around weeks three and four. 

Hair returns at about two to four months post-op. The new growth will initially emerge as finer hairs, gaining length and diameter as the growth continues. By the end of the first year, the new hairs should be as robust as the other, native hairs. 

The “dormant” period between surgery and new hair growth is typically two to three months. However, it doesn’t all grow at once, since each hair has three growth cycles and runs on its own clock. Then new hair will grow at the same rate as non-transplanted hair, approximately one-half inch per month.
