The Most Common Patterns (Sinclair)
Androgenic alopecia is the cause in 3 out of 5 women with chronic progressive hair loss. It is due to an absolute or relative excess of androgen hormones, those associated with testosterone. It has several distinguishing characteristics. A common grading system for the most common visual presentation of this condition is seen below. It is called Sinclair Grading. We use this system to guide our therapy for women with hair loss.
Hair Loss Pattern
Some women with androgenic alopecia have loss of hair mainly from the top and front of the head. The anterior hairline is intact and there is no loss at the temples or top of the head. To reawaken the dormant hair follicles seen in this pattern we use platelet-rich plasma therapy.
The Hamiltonian Hair Loss Pattern
Another way androgenic alopecia presents is with symmetrical loss of hair at both temples and at the very top of the head called the vertex. This pattern is reminiscent of male pattern baldness but fortunately is never as extreme as occurs in men. This pattern is treated with platelet-rich plasma scalp infusions in the area where the hair loss pattern has occurred followed by daily application of a medicated scalp spray. The platelet-rich plasma scalp infusion causes recovery of the dormant hair follicles protects the newly grown hair from falling prey to the harmful effects of androgens again. This treatment allows your hair to recover and naturally flourish once more.
