Is Finasteride and Aldactone combined useful for female patterned hair loss?

I suggest seeing a hair loss expert now to evaluate and go over your condition and test results and provide you information about your best treatment options. There are great non-invasive options like prp/progesterone and/or hair transplantation. See an expert. Best, Dr. Emer

Hello, there are options, please see below. There are multiple solutions to hair loss for women that are nonsurgical including:
Rogaine- There is a specific formulation for women
Supplements- This includes but not limited to Viviscal and Nutrafol which contain marine extract and anti-inflammatory substances to promote hair growth
PRP- Platelet rich plasma can promote hair growth and is a nonsurgical procedure in the office
Low level laser- Can promote hair growth in some patients
Regenerative medicine- There are additional growth factors which can be injected to promote hair growth
Seek advice from an expert or team of experts.

The combination of finasteride and aldactone both work on Androgen dependent hair loss. If you're not seeing a response, I would do a complete workup including history, examination, blood work and biopsy. The diagnosis has to be certain. Many women have multifactorial hair loss with a strong inflammatory component. Neither of these two medications effectively deal with this issue.  PRP does have some anti-inflammatory effect however this may be mitigated when used with A cell. Find a hair loss expert, ask to see photos.PRPHAIRMD.COM 

First, you should not take finasteride at age 27 as a female.  Finasteride can cause birth defects.  Stop this immediately.  
Aldactone or spironolactone can improve female hair loss.  
You should add minoxidil 1.25 mg per day orally and Wnt-act available at the amazon store.  Wnt-act was shown effective in female loss by noted hair loss researcher, Antonella Tosti, from the University of Miami.  Oral minoxidil is superior to topical minoxidil in women. 
Topical spironolactone might be superior to oral.  
As a female, you should test your hormone levels including a DHEA level to rule out other causes of hair loss.  Sometimes a biopsy is good to confirm a diagnosis in women.  

Androgen blockade has the potential to be help female pattern hair loss. Caution is needed with any hormone blocker due to significant harm that can come to a developing baby were a woman to become pregnant on any hormone blocker. For this reason they are frequently used with various strict contraceptive methods.
The combination of hormone blockers can work even better than one alone provided the patient actually has a truly androgen responsive hair loss condition. Most men do. But not all women do. The combination of androgen blocking pills has the potential to be associated with side effects such as depression, fatigue, breast tenderness, breast enlargement, weight gain, decreased libido.If one is not improving, one should reconsider either the diagnosis or treatment options.

Though your labs are normal, there are covert deficiencies which are compensated by the body through mechanism of arresting active hair growth. Have low dose once in 3 days nutritional supplements, these will stop hair loss and induce new hair growth within 3-4 months. Review publications on benefits of nutritional correction in hair loss. 

Since there are not a lot of drugs that are FDA approved to treat FPHL, there are many off label uses for other drugs.  Both of those have shown efficacy in LIMITED circumstances, so you need to find a doc who has experience using them, but yes, they can be options.

Many of today's treatments are not effective for this condition so what we do is offer Scalpl Micropigmentation for such women which is a good cosmetic solution.
