Like minoxidil, finasteride, the active ingredient in Propecia, was originally created with a different purpose in mind -- to treat enlarged prostate glands -- and researchers observed it came with a side effect of hair growth. Unlike topical minoxidil, finasteride requires a prescription, is taken orally and addresses hormonal causes of hair loss. It inhibits the enzyme type II 5-alpha reductase, which converts testosterone into DHT. As it was the first truly effective treatment for hair loss that provided nearly guaranteed results, finasteride revolutionized the hair-loss-treatment industry.
For example, if your hair is thinning because you’ve recently started a new medication or a diet, your approach might be to take an oral supplement or use a laser light device. But if you have hair loss from psoriasis or chemical treatments, you might try a new shampoo and invest in a moisturizing scalp treatment. Throwing everything possible at the problem might not be the most effective method.
Am an Af/Am women 49y.o. almost 50 in a week. Anyway, last april, I removed a weave and saw that around the perimeter of my hairline the hair was so thin, it was virtually bald. I presumed it was due to the weave rubbing against my fine hair; but I later reviewed pictures over the past 8 years and saw how my hair had progressively thinned. My sister and mother confirmed that despite my youthful appearance, the hair thining was likely genetic. I am a can do kinda girl so I sought options. Was evening considering hair replacement "Bosley-style". Long story a little shorter, I boutht this Equate Hair Regrowth after reading just about all of the reviews. Worse thing that could happen was NOTHING, so I would be exactly where I was...thining disappearing hair at the edges. I have used the Equate Hair Regrowth since April 2013 and the hair has regrown around the perimeter and I couldn't be more pleased. I bought for my elder sister 56 y.o. and she had significantly more hair-loss, almost bald edges in fact; now she too has experienced regrowth and was so pleased she recommended it to my mother 74 y.o. and I bought it for her also (she will start applying by the end of the week). Highly recommend this product and note that I have also been taking biotin supplements since April 2013. So, buy Equate Hair Regrowth and biotin for best results. Price can't be beat. Excellent
In either sex, hair loss from androgenetic alopecia occurs because of a genetically determined shortening of anagen, a hair's growing phase, and a lengthening of the time between the shedding of a hair and the start of a new anagen phase. (See "Life cycle of a hair.") That means it takes longer for hair to start growing back after it is shed in the course of the normal growth cycle. The hair follicle itself also changes, shrinking and producing a shorter, thinner hair shaft — a process called "follicular miniaturization." As a result, thicker, pigmented, longer-lived "terminal" hairs are replaced by shorter, thinner, non-pigmented hairs called "vellus."
