A Comparative Study on the Rate of Anagen Effluvium and Survival Rates of Scalp, Beard, and Chest Hair in Hair Restoration Procedures

In 2018, two studies were conducted to compare the survival rates of transplanted scalp, beard, and chest hair in hair restoration procedures. The first study involved 120 patients and found that scalp hair had the highest survival rate at 98%, followed by beard hair at 96%, and chest hair at 92%. The rate of anagen effluvium, a form of hair loss, was also lowest in scalp hair. The second study involved five patients, each receiving 30 hair grafts from each of the three areas. The results showed that during the initial two months, anagen effluvium was significantly less in scalp (40%) and beard (30%) compared to body (53.3%) hair. The survival rate after one year was highest for beard hair (95%), followed by scalp (89%) and chest hair (76%). Both studies concluded that scalp and beard hair are effective donor sites for hair transplantation procedures, but the procedure requires high surgical skill and longer procedural time.
