Hi Elena. I was in much the same spot as you about 2 years ago. What Georgie said is totally accurate, you can't do much about your hair loss before pregnancy, I just used some natural stuff that had probably no effect like castor oil with rosemary oil in It, scalp massage, nizoral shampoo etc. But at around three months pregnant I noticed a dramatic amount less shedding. Went from 20-30 In the shower to 2-3. I didn't see any major regrowth I suppose, but with the reduction in shedding my hair went from pretty dire looking to basically normal (a part dead centre under bright lights maybe looked a little thin, but otherwise it was all good). Such mixed emotions, losing your waistline and your bodily autonomy but every day looking in the mirror and feeling more like yourself as your hair comes back.
Anyway, I had my baby about 7 months ago and the shedding has definitely ramped back up. I'd say I'm still better off than I was before the pregnancy which I wasn't expecting. I suppose it will take a few more months to know exactly where it settles.
One other thing, I know trinov was recommended to you as something that might be pregnancy safe, and I'm not doctor or scientist, but I would be very cautious of that. I believe that the point of it (if im wrong, please correct me) is that it will act a bit like a topical anti-androgen that will not go systemic, but if you were to be preggos with a boy in particular I wouldn't want to touch anything that could potentially have an anti male hormone effect as it might effect the development of his male parts (when preggo you are not supposed to even touch a finasteride pill).
Sorry to derail the discussion of WAY. And also thank you Georgie for organizing this group buy and posting your results. What you have done in this thread one of the most helpful things I have seen on this board and has actually given me some hope for the first time in a while. I wish you the very best of luck and would very much appreciate your continued updates (and those of the others from your group buy)
