How to treat scar hair loss and how to remove surgical scars

Hair loss caused by surgical scars can be improved through medication application, laser therapy, microneedle therapy, hair transplantation, or surgical repair. Scars themselves can be reduced through pressure therapy, silicone preparations, laser grinding, injection therapy, or surgical resection. The specific plan needs to be comprehensively evaluated based on the type of scar and the degree of hair loss.

1. Medication application

Early proliferative scars can be treated with topical application of polysaccharide sulfate cream to improve local blood circulation, while snow glycoside cream cream can help inhibit fibrosis. If accompanied by folliculitis, mopirocin ointment should be used in combination to prevent infection. The medication needs to be used continuously for several months and combined with massage to promote absorption, but the effect on atrophic scars is limited.

2. Laser therapy

Dot matrix laser improves depressed scars by stimulating collagen remodeling, while activating dormant hair follicles. Pulsed dye laser is more suitable for red hypertrophic scars and requires 3-5 treatments with a 4-week interval. After treatment, there is a short scab forming period, which requires strict sunscreen to avoid pigmentation. After surgery, it needs to be repaired with growth factor gel.

3. Microneedle therapy

Roller microneedles or electric microneedles penetrate the epidermis to the dermis layer, stimulating collagen regeneration while introducing hair growth components such as minoxidil solution. For small scar hair loss, the effect is better. It should be treated once a month for 6 consecutive times, and avoid contact with water within 24 hours to prevent infection.

4. Hair transplantation

For permanently damaged areas of hair follicles, FUE technology can be used to extract healthy hair follicles from the occipital region for transplantation. Wait for the scar to stabilize for 6-12 months before proceeding, and the transplant density should be 30% lower than the normal area to ensure survival rate. After surgery, oral antibiotics are required to prevent infection, and transplanted hair will fall off and regrow after 3 weeks.

5. Surgical repair

Severe contracture scars can be treated with Z-shaped surgery or skin flap transfer to release tension, combined with postoperative radiotherapy to suppress recurrence. Linear scars can be re excised and cosmetic sutured, and the tension reducer can be used for 2 weeks. Surgery combined with fat filling can improve depression, but the final effect needs to be evaluated during a 3-6 month recovery period. During scar care, scratching and friction should be avoided, and medical silicone dressings should be used for continuous compression for at least 3 months. Mild shampoo containing caffeine can be used in areas of hair loss, and fragile areas should be avoided when combing hair. Dietary supplementation with high-quality protein and vitamin C promotes repair, and daily sun protection for scars should be maintained for at least 1 year. If itching, hyperplasia or hair follicle suppuration occurs, timely follow-up and adjustment of the plan are necessary.
