Finasteride has relatively few side effects, and a dosage of 1 mg per day costs about $49.50 per month. Women who could be pregnant should not handle finasteride, because it may cause birth defects in a male fetus. Finasteride has not proved effective in the treatment of female AGA and is not FDA-approved for use in women.11 [Evidence level A: randomized controlled trial] Continued use is required to maintain benefits.
Baldness typically refers to excessive hair loss from your scalp. Hereditary hair loss with age is the most common cause of baldness. Some people prefer to let their hair loss run its course untreated and unhidden. Others may cover it up with hairstyles, makeup, hats or scarves. And still others choose one of the treatments available to prevent further hair loss and to restore growth.
I’m so glad you saw my post, and wrote back. Thank you again for writing about your experience. At the time I read it, I knew that was the path I had to go. I have a treatment plan, and intend on it being a successful one (I’m so trying to go from being a negative person to being positive, it really makes a difference). I have joined the network, and hope you do as well,. Angela, is right, there is so much caring, understanding and sharing of knowledge here, that so help with the emotional part of this thing called hairloss.

It is perfectly normal for people to shed 50 to 100 hairs per day. This generally doesn't cause noticeable thinning of scalp hair because new hair is growing in at the same time that hair is shedding. However, hair loss occurs when this hair growth cycle and shedding is disrupted or when the hair follicle becomes destroyed and replaced with scar tissue. Female pattern hair loss (androgenetic alopecia) is the most common form of hair loss in women. This occurs gradually and is caused by genetics (from either side of the family), age, and the action of a specific male hormone, dihydrotestosterone (DHT). This hormone is found in lesser amounts in women and it preys on the hair follicles, preventing them from receiving vital nutrients for proper hair follicle growth, leading to the hairs shrinking, and resulting in a shorter lifespan. Interestingly, DHT does not need to be elevated to generate hair loss. Estrogen, when lowered as commonly seen in menopause, creates a change in the ratio of male to female hormones, giving an edge to these male hormones. Compounded with the sensitivity of DHT to the hair follicles, heredity can affect the age at which a woman begins to lose her hair, as well as the rate of hair loss and the extent of baldness. 
Ironically, taking the hormone levothyroxine to treat an underactive thyroid can contribute to some hair loss, among other side effects, but this seems to be more common within the first month of treatment and more often in children than adults. This hair loss is only temporary and will go away as treatment is continued and thyroid hormone levels stabilize.
