The only evidence i have read for scalp itches is male pattern baldness. which alot of people say they have an itch during male pattern baldness and that finasteride or duta stops that itch. i can't find any evidence to support any other sort of shed that delivers the same kinda itch and thats a stessful thing to hold on too and hope that the hair i am losing won't be just a non-stop shed
I dunno whether you get a scalp itch in a receding hairline pattern with telogen effluvium. its such a huge risk for an unknown feeling thats usually not a good sign for most people with male pattern baldness.
Its also something that was clearly dosage dependent, so one a day would have a stronger itch effect than one every other day.
Although i have noticed a tiny bit more peach fuss appear on the hairline since i stopped taking dutasteride.
If you can shed any light on this stuff then please do. it would answer alot of questions i have about what the hell is going on.
If you feel that one tablet every other day is helping, I think you should do that. Also try 0.25 mg daily or 0.5 mg every other day. From my experience, 0.25 mg vs 0.5 mg was a noticeable difference while 0.5 vs 1 not so much.
I started taking finasteride ten years ago while I was a teenager. I was pretty much stupid and took 2.5 mg daily to begin with. Everything was good then after about 6 month I started to get tingling dry itch scalp with shedding. Looking back the shedding wasnt doing much as my hair didnt take much of a hit but it was a horrible feeling and screwed up my scalp. It was on and off. I went to 1mg daily and sometimes would skip doses in the next few years, and this was greatly reduced.
In 2016 my health and regimen was so fucked up and finasteride wasnt working as well as before. On top of that, it appears that my body simply refused to take anything beyond 0.25mg daily finasteride, otherwise my scalp would be literally burning and losing hair like mad. This always happen after some bad days from finasteride sides, and when the iych comes, my sides would be gone. I tried going off it, my scalp actually felt great for a few days while the sides were not as bad, then the itch came back stronger.
I started taking ZMA early 2018 as I suspect my side effects (fatigue, low sex drive) were due to estrogen. It pretty much erased those sides and I was able to take 0.5mg finasteride without my entire scalp burning for some reason. However I've been going through insane shedding on my right hairline and my entire right side of front is pretty much beyond salvation now It was actually quite stable the entire time I was on 0.25mg.
I suspect that the itch was from some hormonal response of the body to counter the fucked up T/E balance. Apparently, this is my pure speculation based on petsonal experience. My advise is take a lower dosage first but don't go off so easily.
