Telogen Effluvium Miniaturized Regrowth

Question
Dear Dr. Fisher, I suffered a Telogen Effluvium about 1 year ago and my regrowth is coming in thinner.  Will the thinner hairs eventually return to normal density?  The hair loss was triggered by low ferritin, thyroid, and vitamin deficiency.



Thank you.


Answer
What you need is a scalp biopsy to determine exactly what type of hair loss you have.  A telogen effluvium is where the hair goes into a shedding cycle.  This usually lasts from 8-18 months but can be chronic if the ferritin, thyroid and vitamin deficiency are not treated.  Thinning hair is another issue.  This type of hair loss is genetic and is called female pattern hair loss.  The only treatment for this is Rogaine for Men which is stronger than Rogaine for Women.  A scalp biopsy can tell if you have female pattern hair loss.
