Hair loss has many causes, including stress, medications, autoimmune, genetic, trauma, etc. Medical treatments can work and options would include finasteride (propecia), minoxidil (rogaine), PRP (platelet rich plasma), laser light therapy, and vitamins. It is often uncertain which medical therapy will help which patient and so a combination of therapies is typically recommended to maximize benefit. A hair transplant is a surgical option and is appropriate for certain conditions and individuals. The goal of a hair transplant is to provide fuller coverage while preserving a natural appearance. An assessment takes into account such factors as the apparent thickness and curl of your donor hairs, the color contrast between your scalp and hair, your hair loss pattern, your age, and many other factors. The state of the art technique is FUE (follicular unit extraction), performed with a hybrid blunt punch that minimizes graft transection while allowing for the use of the smallest possible punches to minimize donor site scarring while maximizing regrowth. In your situation, I would agree with your estimates. Gary Linkov, MD Hair Specialist Manhattan
