welcome to "Helath Care Magic forum" .
you have alreardy tried many medicines for which u haven't recieve the desired results , stem cell therapy have recently upgraded and no doubt its surely result oriented , but will like to suggest you safer , effective, natural treatment which is homoeopathic medications which will treat the exact cause for your hair loss , as u stated u still going with hairloss so better first stop the hairloss as if you implant stem cells these wont help in your case as still u wil go with the same problem , stem cell therapy
is good fr those areas of scalp
where there is no hair follicle for the hair growth .
so better consult a homoeopath who will help you at this stage of your hairloss , for frurther info pls write drown to (firstname.lastname@example.org)
as u are loosing hair only since a year better start homoeopathic medicnes as these will help to stop the further progress.
wish u good helath always , takecare !
