Bernstein Medical physicians answer the most frequently asked questions on hair transplant surgery. Visit our Hair Transplant FAQ.

Hair Transplant Evaluation

Dr. Bernstein discusses evaluating patients for hair transplantation, and why donor density and miniaturization are critical variables in determining who is a good candidate for surgical hair restoration. Visit the page on Hair Transplant Evaluation.

Candidacy for a Transplant

Patients should meet five basic criteria to be considered a good candidate for hair restoration surgery. Read about the criteria in determining candidacy, plus discussion of candidacy in young patients and female patients. Read Candidacy for a Hair Transplant.

Graft Numbers

The charts on this page will provide a general guideline for the number of follicular units needed in a first and second hair transplant procedure based on the patient’s balding pattern. Visit Graft Numbers.

Large Sessions

In hair transplant surgery, the goal is to achieve the best possible cosmetic result in the context of the patient’s total donor reserves. Dr. Bernstein discusses the advantages and disadvantages of transplanting Large Sessions.

Follicular Units

Scalp hairs naturally grow in tiny groups of 1-4 hairs called follicular units. The term “follicular unit” was introduced into the hair transplant literature by Drs. Robert Bernstein and William Rassman in their 1995 publication, “Follicular Transplantation.” In this paper, they were the first to propose that hair transplant procedures use only follicular units. Read a detailed description of Follicular Units and why they form the basis of all modern hair transplant procedures.

Recipient Sites

Recipient sites are the tiny incisions made in the scalp where follicular units are placed in a hair transplant. On this page, Dr. Bernstein discusses recipient sites, techniques and instrumentation in creating sites, and the importance of proper spacing and density of sites to the outcome of the hair restoration. Read the page on Recipient Sites.

Artistry & Aesthetics

Hair transplantation is a highly technical surgical procedure, but a critical aspect of hair restoration is designing the transplant to provide the best long-term outcome for each patient. Dr. Bernstein discusses how best to conserve donor supply while distributing follicular units for an optimal aesthetic result. Read about Hair Transplant Artistry & Aesthetics.

Shedding After Transplant

On this page, we discuss the causes and effects of shedding after hair transplant surgery, as well as strategies to minimize the amount of shedding after a procedure. It is important to differentiate between post-operative shedding of transplanted grafts and the shedding of normal, non-transplanted hair following a hair restoration procedure.
