How Many Hair Grafts Do I Need?

When you use our hair grafts calculator, you’ll realize quickly that the question is not “how many hair grafts do I need?”. Instead, the important question should be “how much hair do I need?”.  Graft sizes can vary dramatically (1 – 6 hairs per graft).  It’s more precise to calculate how much hair you need and how much donor hair you have to cover thinning areas. 

Our Surgeons may anticipate future hair loss and elect to  transplant certain areas more heavily or lightly. Patients may need more than one procedure depending on their overall hair loss, donor hair density, and hair shaft diameter. Additional procedures may be beneficial depending on future hair loss, goals and expectations. 

Additionally, patients who use preventative therapy in combination with hair transplantation tend to need fewer procedures in the future and maintain a fuller look. Overall health and scalp health play a role in how close together the surgeon can place the hairs and may impact overall fullness. Fullness is often dependent on personal preference, hair diameter and type, donor density, original native hair in the area being transplanted and overall hair loss.

Factors that Influence the Size and Scope of Your Hair Transplant

If you have used our hair grafts calculator, you or someone you care about is probably dealing with hair loss. Below are several frequently asked questions for people who are trying to figure out how many hair grafts they need.  These different factors that play a significant role in determining the scale and specifics of your hair transplant procedure.

Donor hair is harvested from a precise region in the back and sides of the scalp, also known as the donor area. This region is selected because the hair follicles in this area are genetically programmed to be more resistant to the hormone that causes hair loss. As a result, the transplanted hair from this region tends to be more permanent and less likely to fall out.

Consequently, the condition of this region serves as one of the primary determining factors in the quantity of hair that can be transplanted. Should your donor area exhibit a dense concentration of robust hair follicles, your surgeon can procure a substantial quantity of hairs. Employing a microscopic analysis can aid in assessing the donor's health, providing you with a clearer understanding of the anticipated outcomes of your procedure.

  • Do you have scars due to prior FUE or FUT procedures?
  • Is your hair density high or low? One might have as little as 120 hairs per square centimeter or as many as 200 hairs per square centimeter.

The typical hair follicle is composed of an average of 2.5 hairs. Individuals with sparse hair density in their donor area may possess a significant proportion of follicles containing only one hair. Conversely, those with high hair density may harbor multiple follicles accommodating three or four hairs each.

Every person is different.   You may have 120 hairs per square cm. or you may have 200 hairs per square cm.  Your head might be small and narrow or broad and large.  The size of your head and the area of hair loss in centimeters determines the size and scope of your transplant.

  • How large is the area of hair loss
  • How large is the area of donor hair 

The color and texture of your hair significantly influence the outcome of your hair transplant. Individuals with wavy and thicker hair, which has a larger diameter, generally achieve a fuller appearance compared to those with fine, straight hair. Additionally, the interplay of color plays a crucial role. Dark hair against light skin often appears thinner, whereas lighter hair against light skin tends to appear thicker. Conversely, this relationship reverses for individuals with dark hair against dark skin.

The elasticity of your scalp plays a crucial role in determining the quantity of hairs that can be harvested from your donor area. When your scalp lacks elasticity, the process of extracting the desired tissue becomes more challenging. Conversely, a scalp with greater laxity facilitates the extraction of the required donor tissue more easily.

For a patient who has undergone one or more previous procedures, scarring in the donor area becomes a significant consideration. Consequently, this factor influences the total number of hairs available for harvesting. If a patient has undergone an excessive number of procedures, they may no longer qualify as a candidate for further treatment due to the depletion of donor hair resources.

Given that the donor area is expendable, its potential can be compromised under certain circumstances. If an excessive amount of hair has already been extracted from the area in a prior procedure or if it has been impacted by scars or burns, the likelihood of obtaining a high yield of donor hair from this region diminishes.

Several medications can impact the health of your hair and impact the results of your hair transplant. These may include but are not limited to:

  • Chemotherapy drugs: These can cause hair loss as a side effect.
  • Anticoagulants (blood thinners): Some blood thinners may lead to hair loss.
  • Acne medications: Certain acne medications, particularly isotretinoin (Accutane), may cause hair thinning.
  • Antidepressants: Some antidepressants have been associated with hair loss as a side effect.
  • Hormonal medications: Hormonal treatments like oral contraceptives or hormone replacement therapy can affect hair health.
  • Immunosuppressants: Medications used to suppress the immune system, such as those prescribed for autoimmune conditions or organ transplants, may cause hair loss.
  • Steroids: Corticosteroids, used for various medical conditions, can lead to thinning of the hair or even hair loss.

Should you ever require further incentive to quit smoking, undergoing a hair transplant serves as compelling motivation. Smoking restricts the blood vessels responsible for supplying nutrients to the hair follicles. Consequently, this compromises the health of each follicle, potentially leading to thinning or even death

While family heredity offers insight into potential future hair loss patterns, it's imperative to recognize that it's not the sole determinant. Predicting hair loss becomes notably challenging for younger patients, as it's difficult to anticipate the specific areas or extent of hair loss. Consequently, many hair transplant surgeons exercise caution and avoid performing procedures on patients under the age of 25. Premature interventions may lead to unnatural results in the long term.

Hair loss patterns become more discernible as patients reach their late 30's or 40's. Thus, individuals under 25 are advised to explore non-surgical preventative measures for managing hair loss.

Poor health can have various impacts on the success of a hair transplant procedure:

  1. Reduced Healing Ability: Poor health can compromise the body's ability to heal efficiently after surgery. This may prolong the recovery period and increase the risk of complications such as infection or delayed wound healing at the transplant sites.

  2. Decreased Graft Survival: Patients in poor health may have compromised blood circulation, which can affect the survival of transplanted hair follicles. Adequate blood supply is essential for nourishing the grafts and facilitating their integration into the scalp.

  3. Increased Risk of Complications: Certain health conditions, such as diabetes or cardiovascular disease, can increase the risk of complications during and after the transplant procedure. Patients with underlying health issues may be more prone to infections or excessive bleeding.

  4. Weakened Immune Response: Poor health can weaken the body's immune system, making patients more susceptible to infections and other post-operative complications. 

  5. Delayed Recovery: Patients in poor health may experience a slower recovery process following a hair transplant. This can prolong discomfort, swelling, and other side effects associated with the procedure, leading to a longer period of downtime and disruption to daily activities.

  6. Suboptimal Results: Overall, poor health can impact the quality of the final results achieved with a hair transplant. Factors such as nutritional deficiencies, chronic stress, and smoking can all contribute to suboptimal hair growth and decreased satisfaction with the outcome of the procedure.

In summary, maintaining good overall health is essential for optimizing the success and outcomes of a hair transplant. Patients should strive to address any underlying health concerns and follow their surgeon's recommendations for pre-operative preparation and post-operative care to minimize the risk of complications and achieve the best possible results.

Hair transplant patients should have realistic expectations about the outcomes of the procedure. Here are some key points regarding what patients should expect:

  1. Natural-Looking Results: While hair transplants can provide significant improvement in hair density and appearance, patients should understand that the results may not perfectly replicate the original hairline or hair density. The goal is to achieve natural-looking results that blend seamlessly with the existing hair.

  2. Gradual Growth: Hair growth following a transplant typically occurs gradually. Patients should be prepared for a period of waiting as the transplanted hair follicles establish themselves and begin to grow. Full results may take several months to a year to become apparent.

  3. Realistic Hairline Design: Patients should work closely with their surgeon to design a hairline that is appropriate for their age, facial structure, and desired aesthetic outcome. Unrealistic expectations regarding hairline placement can lead to dissatisfaction with the results.

  4. Potential for Additional Treatments: In some cases, additional non-surgical treatments may be recommended to optimize results or maintain existing hair. If hair was added to an area with non-transplanted hair, it's important to use ongoing maintenance to prevent the non-transplanted hair from falling out.

  5. Emotional Adjustment: While a successful hair transplant can improve self-confidence and quality of life, patients should be prepared for an emotional adjustment period. It's normal to experience a range of emotions throughout the process, from excitement about the potential results to impatience during the waiting period.

Overall, patients should approach a hair transplant with realistic expectations, understanding that while the procedure can provide significant improvements in hair appearance, it is not a cure for hair loss, and individual results may vary. Open communication with the surgeon and a thorough understanding of the process are key to achieving satisfactory outcomes.

How many grafts in a single procedure?

Our main objective is to deliver more hair in a single procedure along with natural looking results. At PAI Medical Group, our trademarked procedure consists of custom graft sizes uniquely prepared for each patient, which is why the number of grafts is irrelevant. Artistic placement and number of hairs per graft is our main focus. 

We offer two procedure types, FUE and FUT. If you used our hair loss calculator, you should have a better idea of what procedure might be right for you.  

Multi-Unit Hair Grafting™ (FUT)

Under optimal conditions, a substantial Multi-Unit Hair Grafting™ (MUHG) procedure has the potential to yield between 7,000 to 9,000 hairs. Various factors impact your suitability for the procedure, as well as the scale and extent of your treatment.  MUHG is well suited for patients who need multiple procedures because it preserves the donor area.

ARTAS Robotic (FUE)

An ARTAS Robotic FUE procedure can yield as many as 5,000 hairs in a single procedure. It’s crucial to acknowledge that due to the characteristics of FUE, there are constraints on the number of subsequent procedures a patient can have.
