How many hairs do you need in a Hair Transplant?

21 Feb, 2022

Before we get to this response, lets clear the air between “hair” and “grafts”, as we have seen many people, and shockingly even hair transplant clinics use these words interchangeably, not realizing how stark the difference between the two is.

Hair – A follicle is a single hair from a group or follicular unit.
Grafts / Follicular Unit – Hair does not grow in only single hair groupings, instead most people’s hair will grow in groups of 1, 2, 3 or 4 hairs. These groups of hairs are referred to as a Graft or a Follicular unit. On average, each person has 2 hairs in each Graft.

Now that we know the difference between Grafts and Hairs, the first step to finding out the correct number of hairs that you will need at the optimal density, is to have a consultation with a hair loss specialist.
During consultation, your scalp and hair will be examined, the extent of your hair loss will be measured, your medical history will be considered and a proper diagnosis for your hair loss will be made. To classify the extent of hair loss, the Norwood Scale is used for men and Ludwig scale is used for women.

Some of the factors that must be considered before calculating the grafts required:
1. Extent of thinning
2. Age of patient
3. Medication the patient is already taking
4. Quality of the donor hair
5. Further genetic thinning
6. Density required to achieve a natural look
7. Patient expectations

With all this information, a correct calculation for the number of grafts needed will be provided.
In our experience, the approximate grafts needed as per the scale is mentioned below

How come this number is generally different for other Hair Transplant clinics I visit?

Because techniques/ experience and survival rates vary greatly between hair transplant clinics. Those with poorer survival rates will increase the number of grafts needed, whereas experienced hair transplant clinics will only take what is required to achieve the result.

The Evolved Hair Transplant Difference

Evolved Hair Transplant Clinics consistently achieve over 95% survival of grafts vs the industry rates that fluctuate between 50-90%. This high survival rate leads to fewer grafts needed. And leaving the donor area fuller and with far less trauma.

The Evolved DFI high survival rate is achieved by:

Handling – Minimum handling of follicles
DFI technique – the most delicate Hair Transplant method, referred to as microsurgery
Bio tissue preservation – Evolved is one of only few hair transplant clinics that use Bio Tissue preservation in our hair transplants, which sustains the survival rate of the hairs up to 100%.
Who does your procedure – All procedures are completed from start to finish by a Certified Master Surgeon, not technicians/ nurses.
