Sorry about your hair loss. That's frustrating and really hard on a female! You say you have a deficiency of vitamins. Which ones? Deficiency in Vitamin D is well known to be linked to alopecia or hair loss. Another issue that women sometimes have is that they don't eat enough calories or protein for hair. So, in general, how is your diet? Being low in zinc, vitamin A, vitamin C and protein can all lead to hair loss, unfortunately. But you can change your diet and begin supplements to help.
What does hb stand for? Are you stressed out or anxious? That can also lead to hair loss.
And please know this can get better. If you are thinking of self harm, please reach out. hugs
Oh, that's okay. I don't need to see your personal report and do caution you for offering anything personal like that to strangers on the internet including things like email address or contact information. Keep that stuff private.
So, if you say "yup, vitamin D" . . . well, what about supplementing vitamin D?? What about supplements in general? Talk to your doctor about that. This seems an easy (ish) remedy.
Oh, okay. That's different than vitamin deficiency. Here's information on androgenic alopecia https://www.webmd.com/skin-problems-and-treatments/hair-loss/hair-loss-types#1. Both men and women get it and in men, it's called male pattern hair loss. I guess you can start the supplements if your doctor says okay for good measure. But, it probably won't help too much if vitamins aren't the issue. Alopecia is harder to treat. I caution you against things like rogaine because once you start using it you have to keep doing so or the hair you have grown will fall out.
Can you get a second opinion? Your doctors recommendations sounds like things he does in his office to make money. :>) Normally I trust doctors but this is kind of strange. You can make your own antioxidant with green tea and drink it. Just do a google search and you will get the info to do that on your own since you say you can't afford the doctor's in office 'therapies'. And biotin and oils for hair. Well, I'm not sure how that treats alopecia. I'm not a doctor though. Personally, I think you can use biotin oils (caster, grape, coconut) yourself. Google how to do this too and save money.
