Ringworm on the scalp may require the use of an oral drug, such as griseofulvin, because creams and lotions applied to the affected area may not get into the hair follicles to kill the fungus.
Hair loss usually develops gradually and may be patchy or diffuse (all over). Roughly 100 hairs are lost from your head every day. The average scalp contains about 100,000 hairs.
Think about it. Two years is a long time for hair to be subjected to the daily wear and tear of the environment, washing, drying, brushing, combing and any chemical processing. Just imagine what a piece of silk or fine fabric would look like after 2 years of constant handling.

Call your doctor if:
You are losing hair in an atypical pattern.
You are losing hair rapidly or at an early age (for example, teens or twenties).
You have any pain or itching associated with the hair loss.
The skin on your scalp under the involved area is red, scaly, or otherwise abnormal.
You have acne, facial hair, or menstrual irregularities.
You are a woman and have male pattern baldness.
You have bald spots on your beard or eyebrows.
You have been gaining weight or have muscle weakness, intolerance to cold temperatures, or fatigue.
For hair loss due to heredity, age, and hormones, the topical medication Rogaine (minoxidil) can be helpful for both male and female pattern baldness. Expect to wait 6 months before you see results. The oral medication Propecia (finasteride) is effective in some men. This medicine can decrease sex drive. When either medication is stopped, the former baldness pattern returns.
Unfortunately many people are not aware of the fact that while hair can be extraordinarily resilient, once it has emerged from your scalp is has no facility for renewing itself. It is considered to be dead protein.
