Eyebrow loss signifies a range of disorders in the body, from eyelid inflammation to a variety of autoimmune disorders, according to the International Journal of Trichology. The loss of the eyebrows is a clinical hallmark of leprosy in India.
Eyebrow loss is known as madarosis and may also result in scarring of the skin. Dermatitis, psoriasis and rosacea may all include eyelid inflammation that can result in the loss of the eyebrows, informs the International Journal of Trichology. Eyebrow hair is also affected at the follicular level by certain systemic disorders, including hypothyroidism, alopecia and lupus. Madarosis occurs in the presence of certain infections in addition to leprosy and as a side effect of the use of certain drugs. Individuals experiencing these symptoms should consult with a physician to determine the underlying cause and treat the condition.
Management of eyebrow loss is dependent on identifying and treating the underlying condition, advises the International Journal of Trichology. When no scarring has occurred, hair begins to regrow following treatment of the cause. If scarring has occurred, hair transplant is necessary as the hair is not able to regrow. The exception is leprosy, where regrowth does not occur despite the lack of scarring.Learn More

Normal ScvO2 values are equal to about 70 percent.Full Answer >
