The study will include 20 patients with cicatrical alopecia.Patients will be randomly assigned into two groups:Group (A):include ten patients will undergo (FUE) alone.~Group (B): include ten patients will undergo(FUE) and (PRP).3-Surgical technique:~Preoperative Investigations including complete blood count, coagulation profile and hepatitis viral markers.~1-Group(A): will undergo (FUE)~Washing the scalp with antiseptic shampoo before the procedure.~Tumuscentanaesthesia:The donor area is anesthetized with a lidocaine 1% solution diluted with 20 cc saline in addition to adrenaline.~Creation of micropunches(0.7-1 mm) using micromotor.~After removal of the punch,the follicular unit is extracted with Jweler's forceps.~Extracted grafts are then placed on chilled saline gauze for maximum four hours until ready for transplantation.~The recipient area is prepared with rectangular scalpel blades 1mm or hypodermic blades 0.9 mm.~Implantation using fine tipped jweler's forceps.~Finally, receptor and donor areas will be softly cleansed with saline and crepe bandage is applied.~2-Group (B): FUE+PRP~The same procedure will be done but grafts will be placed in Prp solution.~Prp session one week before transplantation then monthly for 3 monthes after (FUE).~Preparation of PRP~10 cc blood will be aspirated in test tube contained a modified solution of anticoagulant,called acid-citrate-dextrose type (ACDA), in which the physiological pH will reached to preserve the platelet integrity.~The first spin of whole blood sample will be at 2500 rpm for 4 minutes~The second spin at 4000 for 20 minutes for obtained plasma.~Platelets are separated as a pellet at the bottom of the tube from platelet-poor plasma (PPP) above. The platelet-rich pellet is resuspended in remaining amount of plasma. The resulting suspension is used as PRP.~Prp is injected in the recipient area. 4-Follow up:~Follow up clinically by digital photographs and trichoscopy 1 week after operation, after 3 months and after 6 months.
