Understanding Of A Hair Transplant

Anatomy of a Hair Transplant Surgery

At the Nova Medical Hair Transplant Clinic, we offer the New Jersey hair transplant as a fantastic solution for any individual who is experiencing significant hair loss commonly caused by stress, aging, and genetics.

The procedure is a simple and pain-free way of restoring luscious locks to your head and confidence to your character. The latest hair transplant techniques focus on the scalp and its hair, using methods like follicular unit extraction (FUE) to extract and implant individual hair follicles. Further understanding of a hair transplant can be supported by learning the anatomy of the scalp.


Our scalp is composed of five different layers. A neat little mnemonic to remember these layers is SCALP.

S represents the outermost layer of skin in which the hair grows. It also contains the sebaceous or sweat glands, and hair follicles.

C is for the connective tissue that is found underneath the layer of skin. This is a layer of dense, subcutaneous fat and some fibrous tissue that is home to nerves and blood vessels of the scalp. This subcutaneous layer is highly vascularized, and care must be taken during the hair transplant surgery to avoid damage to the blood vessels, which can impact circulation.

A stands for aponeurosis, the third layer of the scalp. It is sometimes referred to as the epicranial aponeurosis and it is a tough layer of dense fibrous tissue that connects the frontalis muscle at the front of the scalp to the occipitalis muscle at the back of the scalp.

Important Part Of Your Scalp Anatomy

New Jersey Hair Transplant

L is the loose areolar connective tissue that provides a layer of separation between the upper three layers of the scalp and the pericranium. It is this layer that also provides an area of entry for craniofacial surgery or neurosurgery. In part of that, the loose areola connective tissue can sometimes be referred to as the “danger zone” because infections can occur throughout this layer, onto emissary veins and spread into the cranium. With proper surgical sterility though, the risk of infection can be minimized.

The loose areolar connective tissue is composed of bundles of collagen type 1 and collagen type 3. It is also rich in glycosaminoglycans, which is predominantly found in its matrix form. This layer also allows for the superficial layers of the scalp to be mobile relative to the pericranium.

P represents the pericranium, which is the fifth and last layer of the scalp. It is a dense layer of connective tissue that lies over the skull and is heavily vascularized. It provides the bones of your skull with nutrients and the capacity for cellular repair.

In addition to the scalp, hair follicles are an important part of your scalp anatomy and especially crucial for a New Jersey hair transplant. As mentioned, the layer of skin on the scalp is where the hair follicles reside and extend into the subcutaneous connective tissue layer. When an individual experiences hair loss in a particular area of the scalp, there is also thinning of the skin and connective tissue layers.

At the Nova Medical Hair Transplant Clinic, our doctors and medical professionals have extensive knowledge of the scalp and its anatomy. Therefore, you can rest assure that we can provide you with amazing results from your New Jersey hair transplant. To learn more, we welcome you to schedule a consultation at our clinic.
