When it comes to hair, people tend to think of “three thousand worry lines”, but if there is a scar in this hair that does not grow, I think that is the real worry! In the consultation room, Zhang took off her hairpin and lifted her hair to reveal an egg-sized scar on top of her head. Since his childhood injury left this scar, Zhang has been using a hairpin to hold his hair firmly in place, fearing that his hair would fall apart and reveal the scar. For more than a decade, Zhang’s hair has remained unchanged, all because of the scar on top of his head that does not grow hair. After seeing Zhang’s condition, the doctor decided on a treatment plan of “scar removal combined with hair transplantation”. Many patients with scars on their scalp have similar painful experiences to Zhang’s. We often see patients who come to the clinic with no abnormalities, but when they take off their wigs or lift their hair, they can see their sore spots – scalp scars. When the scalp is damaged, the hair follicles become necrotic and the wound heals, leaving a scar that does not grow hair. The most common scalp scars in outpatient clinics are due to scalp burns, open-heart surgery, debridement surgery and scalp infections. Scars do not affect life, but can become a heartache for patients who struggle to hide them from others and long to have their scalp scars removed and get their lush hair back. Three ways to make scalp scars disappear from sight First, scalp scar excision is suitable for patients with loose and elastic scalp scars. The surgery can remove scars up to 2-3cm wide, and for some patients with larger scars, they can be removed in stages. This procedure can effectively remove small scars or reduce large scars. Second, excision of scars after scalp implantation of dilators For scars with a width of more than 5cm and an area of less than 1/2 of the entire scalp. In the first surgery, an expander is buried under the normal scalp, and the normal scalp area is enlarged after about three months of water injection and expansion. The second surgery cuts out the scar and covers the wound with the expanded normal scalp. This procedure is effective and can repair large scars, but the treatment period is somewhat long and patients need to arrange their time wisely. Third, hair transplantation is suitable for small scars, which are of certain thickness and soft texture. The procedure involves extracting hair follicles from the normal scalp and transplanting them to the scalp scars, allowing hair to grow on the scars and cover them up. Although the survival rate of the hair follicles on the scar is slightly lower, it is possible to grow thick hair on the scar after 1-2 surgeries. The advantage of hair transplantation is that the surgery is less invasive, no hospitalization is necessary, the treatment period is short, and it does not interfere with life and school work. The most outstanding point is that hair transplantation can control the direction, angle, density and thickness of hair, can recreate an aesthetically pleasing hairline, and can provide targeted and precise treatment for scattered irregular scars. The above three treatment methods for scalp scars have their own advantages and disadvantages and require a professional doctor in a regular hospital to choose the best treatment plan according to the specific situation of the patient. Combining two or three methods for treatment to complement each other’s strengths is a better choice.
