Dear Dr Rassman,
I am a male, 45 years of age. My question is – I have had two transplants and the results are not that great because I have fine hair, which was very thick in the past. I have been suffering from anxiety and depression for 20 years plus and I am currently taking prozac. Will my illness cause my transplanted hair to fall out? there is history of family hair loss.

There are many variables that can impact hair growth, including the drug Prozac (fluoxetine) that you’re taking. Depression can also cause hair loss, as you’re aware. Usually though, transplanted hairs are more resistant to hair loss than the genetically impacted hair which will more readily die off with stress in some people.
In other words, as long as your transplanted hair was taken from the permanent donor area, I would not expect it to fall out.

It’s normal to lose hair in the shower, as the water can dislodge some of the trapped hair (from hairspray or other styling agents) that would’ve fallen out throughout the day as part of the normal hair cycling process. That part doesn’t sound unusual to me.
