How effective is Loniten 1.25 (oral monoxide) for hair growth in women 51 years old?

In my experience, oral Minoxdil works well with female pattern hair loss. We often combine it with an anti androgen such as finasteride or spironolactone well as  PRP. Treatment of scarring Alopecia depends upon how long the scarring has been present. I think it's important that you use a lower dose of Loniten such  as .25 mg. The side effect profile is superior are we have seen good results.

I recommend getting a formal evaluation with a hair loss expert to go over your condition and advise you on best treatment options. There are great non-invasive options like prp/progesterone that work well with Minoxidil. Hair transplantation is an alternative. See an expert. Best, Dr. Emer 

It can be more effective but is is associated with a greater range of side effects. Make sure you are followed by a physician who is knowledgeable about oral minoxidil. Topical must be stopped in anyone using oral minoxidil. Oral minoxidil is not FDA approved. This does not address scarring (cicatricial alopecia) so make sure that you review with your dermatologist appropriate treatment for your particular scarring alopecia. Low level laser and finasteride present other options for treating androgenetic alopecia. Together with your dermatologist, you can determine if this is appropriate for you.

Oral minoxidil is effective in growing hair however, for women, it may also grow beard and other facial hair as well
