This article prepared by the Private Nişantaşı Polyclinic. Is Hair Root Transplantation Possible From Someone Else? It has been prepared to give information about your question. Unlike an organ transplant, your donor for a hair transplant is yourself. There is no transmitter and no receiver. When hair, hair follicle (graft), follicle and tissue is taken from someone other than an identical twin, the body will reject the treatment without drugs that suppress the immune system.
Hair transplantation, known as autologous transplantation, where only their own hair can be transplanted, is usually a surprise for patients. Although we call the transplanted hair “donor hair” or “donor follicle”, it is the donor himself. It usually comes from DHT-resistant areas of the scalp – usually the back of the scalp. This is because your body does not accept and reacts to the hair transplanted from another person unless immunosuppressant drugs are used, which can cause dangerous side effects.
Hair serves a variety of functions, including protection, sensory input, thermoregulation, and communication. For example, the hair on the head protects the skull from the sun. Hair on the nose and ears and around the eyes (eyelashes) protect the body by trapping and excluding dust particles that may contain allergens and germs. Eyebrow hairs prevent sweat and other particles from dripping into the eyes and causing discomfort.
Hair also has a sensory function due to the sensory innervation of a hair root plexus that surrounds the base of each hair follicle. Hair is much more sensitive to air movements or other environmental problems than the surface of the skin. This feature is also very useful for detecting the presence of insects or other potentially harmful substances on the skin surface. Each hair follicle is connected to a smooth muscle called a rector pili, which contracts in response to nerve signals from the sympathetic nervous system and “upright” the outer hair shaft.
Its primary purpose is to trap a layer of air to add insulation. This is seen as goosebumps in humans and is even more evident in animals, such as when a frightened cat lifts its fur. Of course, this is much more obvious in organisms with heavier hair than most humans, such as dogs and cats.
Hair Root Transplant from Someone Else | Hair Greft
Hair is a keratinous filament that grows from the epidermis. It consists mainly of dead, keratinized cells. Hair strands originate from the epidermal penetration of the dermis called the hair follicle. The hair shaft is the part of the hair that is not fixed to the follicle, and most of it is exposed on the surface of the skin. The graft is referred to as the hair follicle, and it is observed that the rest of the hair fixed in the hair follicle remains below the skin surface. The hair root ends at the hair root deep in the dermis and contains a layer of mitotically active basal cells called the hair matrix. The hair bulb surrounds the hair papilla, which consists of connective tissue and contains blood capillaries and nerve endings from the dermis.
Just as the basal layer of the epidermis creates layers of epidermis that are pushed to the surface as the dead skin sheds on the surface, the basal cells of the hair follicle divide and push the cells outward from the hair root and body as the hair grows. The medulla is surrounded by an outer layer of very tough, keratinized cells known as the cuticle. It forms the central core of the hair, surrounded by the cortex, a layer of compacted, keratinized cells. These layers are located in a longitudinal section of the hair follicle. But not all hair has a medullary layer.
The wall of the hair follicle consists of three concentric layers of cells. The cells of the inner root sheath surround the root of the growing hair and extend to the hair shaft. They are derived from the basal cells of the hair matrix. The outer root sheath, which is an extension of the epidermis, surrounds the hair root. The hair root is formed from basal cells at the base. It tends to be more keratinized in the upper areas. The vitreous membrane is a thick, transparent sheath of connective tissue that covers the hair root and connects it to the tissue of the dermis.
Hair Growth & Hair Color
With the growth and loss of the hair, new hair takes its place. This occurs in three stages. The first of these is the anagen phase, in which the cells divide rapidly at the hair root and push the hair shaft up and out. The length of this stage is typically between two (2) and seven (7) years and is measured in years. The catagen phase lasts only two (2) to three (3) weeks. It marks a transition from active growth of the hair follicle. Finally, in the telogen phase, the hair follicle is at rest and there is no new growth.
At the end of this phase, which lasts about two (2) – four (4) months, a new and different anagen phase begins. Basal cells in the hair matrix then produce a new hair follicle that pushes out the old hair as the growth cycle repeats itself. Hair typically grows at a rate of 0.3 mm per day during the anagen phase. An average of fifty (50) hair follicles are shed per day. Hair loss occurs when more hair is lost than replaced. It can occur due to hormonal or dietary changes. Hair loss can also be caused by the aging process or the effect of hormones.
Similar to skin, hair gets its color from the pigment melanin produced by melanocytes in the hair papilla. Different hair color is caused by differences in the genetically determined melanin type. As the person ages, the production of melanin decreases and the hair starts to lose its color and turn gray and/or white.
What is Hair Graft Transplantation?
Hair texture (straight, curly) is determined by the shape and structure of the cortex and the medulla to the extent it is present. The shape and structure of these layers are also determined by the shape of the hair follicle. Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells accumulate in the hair follicle, the hair shaft is pushed through the follicle towards the surface. Keratinization is complete when cells are pushed to the skin surface to form the visible hair shaft.
The outer hair is completely dead and consists entirely of keratin. For this reason, there is no feeling in our hair. You can also cut your hair because the cut is superficial. You can even shave without damaging the hair structure. Hair removers, most of them chemical, also act superficially; however, electrolysis and pulling cause the hair follicle to be destroyed so that the hair cannot grow back.
Hair follicle transplantation is a practice in which plastic dermatological surgeons move the hair to a bald area of the head. The surgeon usually removes the hair from the back or side of the head to the front or top of the head. Hair transplantation is typically performed under local anesthesia in a medical office. Pattern baldness is responsible for most of the hair loss. This is a genetic problem. The remaining cases are due to a variety of reasons, including:
- Hormonal imbalance
Are There Different Types of Hair Transplantation?
Many people who want to have a hair transplant wonder if it is possible to transplant hair follicles from someone else. There are two types of transplant procedures: cleft grafts and micrografts. Slitgrafts contain four (4) to ten (10) hairs per graft (hair root). Micro-grafts are one (1) to two (2) hairs per graft, depending on the amount of coating seen as needed.
Who Can Benefit From Hair Transplantation?
When you want to improve your appearance and self-confidence, you can consider having a hair transplant. Good candidates for a hair transplant are those who:
- Men with male pattern baldness
- Women with thinning hair
- Anyone who has lost hair from a burn or scalp injury
Hair follicle transplant is not a good option for:
- Women with a common form of hair loss across the scalp
- People who do not have the necessary “donor” hair area to grow hair for transplantation
- People with keloid scars (thick, fibrous scars) after injury or surgery
- People whose hair loss is due to drug use such as chemotherapy
