hello there and thanks for writing to HCM
i have read your history and understand your concern.
how old are you?are you on any medications?what sickness did you have 14years back?any other medical history?have you checked for
thyroid function?any family history?are your nails healthy?
these details would have helped
Coming to the query,From your description of a small,smooth patch of hair loss it points towards a diagnosis of
alopecia areata according to me.
Its common under 20years of age but can affect any age.Its basically our immunity affecting and attacking our hair follicles.
if this is the case,fortunately for you,it is not permanent.
i would recommend ,getting a thyroid function test done and hair and scalp
analysis done to rule out thyroid disorders and dandruff
usually the hair slowly grows back;most common treatment for patchy hair loss is many injections of
corticosteroids into the scalp or skin, about 1 cm apart, every 4 to 6 weeks can be tried
Minoxidil also is effective along with corticosteroids and you can even try different styles for covering the patch temporarily.
If you
seborrhoeic dermatitis or dandruff,
ketoconazole shampoo on scalp thrice a week for a month will help
have a healthy diet and plenty of water and take a
multivitamin tablet daily.
Hope it helps and relieves your concern.followup if needed.good day.
