sir,
I am a 25 yr old asian female and suffer from androgenetic alopecia(aga) for last 4 yrs. my question is when you say advanced thinning what do you mean by that?? i mean approximately after how many yrs after the process of miniaturisation has started will the chances of reversal thru minoxidil will be difficult?? lets say in my case i have lost more than half of my hair and in the front where scalp shines vellus hairs (thin fine white in colour less than 1cm) are present. would you call it advanced thinning or extensive miniaturisation making minoxidil difficult/impossible to work??
For women, there are no good rules to follow so I can not answer your question. Try the minoxidil and watch it over a 12 month period and you will then know the answer to your question. Time must pass and twice a day use needs to be maintained.
