Hair loss, now-a-days, is common among males and females of all age groups. We all lose some hair strands every day, however, some people lose more than normal strands in a day that can cause severe hair loss. Hair loss is mostly genetic, so if hair loss runs in your family, you are most likely to suffer from hair loss too. Hair loss happens either in clumps that is overall hair loss, or focussed on any one part of head - especially the crown. While genetics play a big role, some additional factors can aggravate hair loss - hormonal imbalance, stress, thyroid disease, anemia, protein deficiency, and low vitamin levels may cause hair loss in you. There are many treatment options for hair loss including medications, home remedies and procedures such as PRP, Stem cell therapy.  There are various over the counter medications available for preventing hair loss, but you need the ones most suitable to your hair to get effective results. Visit a dermatologist in your area to know which medicines you should take.
