Increasing density after 1st hair transplant?

For patients that need a high number of grafts to achieve coverage and density across the scalp, multiple hair transplant surgeries may be necessary. When hair transplants are done properly and with the most up-to-date techniques, there is minimal scarring (or scar tissue). Without seeing pictures or having an in-person consult, it’s hard to determine your candidacy for a second procedure. But if your first hair transplant was done properly and with modern techniques, you most likely won’t have a problem with getting a second procedure to achieve greater density, granted you have a healthy, full donor region.

Receiving a second hair transplant to increase the density is very common.  The amount of coverage attainable from a hair transplant depends on several factors including the quality of your donor hair.  Undergoing a second transplant can be quite successful in achieving more density. 

Hello,Density is one of the most critical factors after hair transplantation.  Early on you may not be able to fully determine your density.  Density depends on various factors including the number of hairs  per cm squared, the thickness and vibrancy of hair, direction and design of hair.  Techniques for density vary from surgeon to surgeon.  In my office, we utilize a specialized technique that allows for optimizing density and found it to be helpful.  Best, Dr. Anil Shah

Many patients go on to have a second hair transplant surgery to increase their hair density and address further hair loss. 

It is clearly possible to increase your density by adding a second procedure or pass through the area where you had your first transplant.  A second pass is often performed to increase coverage as hair loss progresses.  If the first pass has a thin density, you can increase density by adding a second pass in the same area.  Often times, a second or third pass is necessary in the crown or back of the head, while a dense packing alone suffices in the front of the scalp.  In a bald scalp, well performed hair transplantation actually improves circulation to the scalp.  A second pass is a great way to add more density following a properly performed hair transplant procedure.  
Of course, as in any field, there are poorly performed hair transplant procedures that can kill existing hair, leave patients with pitting, ridging, and a pluggy, unnatural appearance.  Procedures like this can poison the skin and make it difficult to get good growth in subsequent procedures.  In other words, do your home work first.  Don't depend on sites that recommend doctors for a fee.  Many of these sites recommend some poor physicians and relatively novice physicians, as well as some good physicians.  Really good surgeons don't require a someone claiming to be a hair transplant mentor, hair transplant patient advocate, or paid hair transplant consumer advocate to promote their good work.  If you do your homework well, you will not need to worry if the second pass will add density, because the second pass will add density.  If you take the advice from a paid advocate, you can expect good results, average results, lack luster results, or poor results.  Remember, these individuals are charging physicians $12,000 or more annually to recommend physicians.  Greed can get in the way of good judgement so proceed cautiously.  Advocates will also steer you away from the very best physicians, who do not pay their marketing fee.  There is something inherently wrong with that system and attempt to monopolize the industry through their refusal to deal.  
There is something else to consider if you add more hair.  Suppose you had no hair before your first procedure and you have 2000 grafts.  A year later, you will be 100% better.  However, if you add 2000 more grafts in the same area a year later, you will now have 4000 total grafts, but you will be only 50% better.  

Usually, there is space in between the transplanted grafts which is visible under high magnification.Thus,you can undergo the second transplant in the same area but it will require more expertise than the one for the first surgery.

Depending on size of the incisions, depth of incisions and the density of the first procedure, there will be some microscopic scarring in the recpient area. This could affect blood flow on subsequent surgeries. 
The second procedure has to be at a lower density and close attention needs to be paid to the behaviour of the skin during surgery to make sure blood flow to the recpient is good. 

Typically there is minimal to no damage done to the scalp with a proper hair transplant using modern techniques. Having multiple procedures is very common, and if done properly with an experienced surgeon, the patient should have very successful hair growth and be completely satisfied with the results of the procedure.

As long as your surgeon knows what they are doing getting a second procedure done to increase density should pose no risk to hairs transplanted during the first procedure. Having multiple procedures is fairly common.

Thank you for the post and question. Considering a 2nd procedure to add density is very common. The final outcome of course is dependent on he strength of the donor region, and overall health and condition of the skin. You should wait atleast 12 months post procedure prior in booking your 2nd procedure. Hope this helps.
