I was placed on Effexor 75 mg in conjunction with my ambien for insomnia. I have been on Effexor for two years. 'My hair used to be long and healthy. I have been wondering lately what in the world is wrong with my hair?? I use good products, take biotin and it does not seem to matter. Then I started wondering if it was my medicine? My hair is so dry and brittle. The ends are see through and breaking off. Stopped taking Effexor about 3 weeks ago. Looking into All natural supplements to help with sleep.  Going to get my hair cut tomorrow
