Hair can be transplanted on scars, anywhere, or on any part of the body, even on the scalp. The hair donor is the follicle root and we can transplant it into the growing scar.
In areas with scar tissue, the blood supply is reduced compared to normal areas of the scalp. When the tissue is thickened and lifted, local steroid injections can help flatten and smooth the tissue around the scar so that hair transplants can be performed normally. Hair transplants can grow on scar tissue, so it is possible to perform a hair transplant on a scar.
The scar tissue itself does not allow hair growth, but what is known as scar tissue-grown hair is increased hair follicle growth when hair follicles are transplanted into the area. Areas scarred by burns, accidents, operations, radiation or other causes can in many cases support the growth of eyebrows through transplantation methods. If there is a suspicion of hair growth on the scar, small-face transplant tests can be conducted to assess the health of the scar.
In hair transplantation, also known as scar revision surgery, hair follicles are transplanted into the scarred area. For successful growth of the eyebrows, complete transplantation is performed in which living or adult follicles are removed from the back of the scalp and transplanted into the scar area.
Hair cannot grow on scarred skin because the follicles are destroyed. Hair follicles can regrow on scar tissue that comes back to cover the visibility of the scar.
In some cases, a person with scalp scars may use hairstyles to make scalp scars invisible. However, the size and placement of the scars can make it impossible to disguise this with hairstyles.
Individuals with scars on the scalp may complain about a lack of hair growth around the scars. Areas of hair loss may feel smoother than hair, but they can be more sensitive and painful or sore after healing. As the skin of the body heals, some forms of scars are inevitable, and different scars on different parts of the body may be less conspicuous or more pronounced than others.
In many patients with disfiguring scars, bald hair can cause major emotional trauma, as it heals more slowly than scars and has a generally poor blood supply.
Blood supply is an essential part of successful follicle growth and regeneration as it is the transport system for oxygen and nutrients to the hair follicles.
In humans, wound healing leads to scarring, in which fibrous tissue replaces normal skin. In humans, scar tissue contains excess collagen and is free of hair follicles and skin fat.
This would not be a big deal if the scar in question were tiny and, for example, on the elbow. However, scientists have found that the scar in mice reaches the minimum size for hair growth.
We took biopsies of the wound or scar area to determine the exact cause (bacteria or fungi) and examined the health of hair follicles to determine the severity of the disease. We were able to help hair follicle formation in the wound region by treating the wound with WNT proteins before the scar formed. We used scalp hair, but we could also use other body hair to camouflage the scar.
Chronic skin diseases are characterized by an inflamed wound, which begins as a red, inflamed spot with a scaly, encrusted appearance. If the hair follicles are damaged, the wound can lead to scar tissue that can cause permanent hair loss. This type of scalp reaction to an injury leads to a lesion that causes scars that can lead to the death of hair follicles and permanent hair loss – we call scarring alopecia – pain.
Head injuries include injuries to the scalp and eyebrows that lead to the destruction of hair follicles on the scalp or eyebrows. The most common cause of head injuries are car accidents, in which jagged metal or glass can cause injuries that heal without extensive scars. Some people suffer head injuries in childhood accidents and are scarred for the rest of their lives.
The answer is that hair transplants on existing scar tissue can be performed and there are many successful examples of this. If you have scar tissue on your scalp from trauma or burn or from a previous hair transplant, you may consider a hair transplant to hide the scar tissue. You may want to do this, but are concerned that your scar tissue will prevent you from benefiting from it.
Hair regrowth from damaged skin is an unmet medical need, says Ito, because of the disfigurement of those who have suffered thousands of traumas, burns and other injuries. He says scientists have long believed that part of the healing process is scars and collagen-building up in damaged skin and that this is behind his inability to regrow hair. His immediate aim is to signal the mature skin to return to its embryonic state so it can grow new hair follicles, similar to ruined skin in people who have gone bald with age.
FUT (Follicular Unit Transplant Striping) is a method of hair transplantation that leaves a linear scar or strip of skin taken from the donor area of the scalp to harvest healthy hair follicles. The scarred area on the scalp is reduced by surgical excision and repair and leaves a smaller area that requires a hair transplant. Qualified and experienced doctors and hair restorers have successfully transplanted hair into scarred areas of the scalp (see scar alopecia).
Fue shaved and harvested 300 grafts from the back of her head and transplanted them into the scar. One month after the transplant, I performed two rounds of hair follicle regeneration treatment to prepare the scar for improved blood supply. The second case was a young patient who had had a scar on his scalp since birth.
