Well, there you have it, folks. Without legitimate clinical evidence, there's no way of telling whether castor oil is the hair-care cure-all some people claim it is. That being said, as long as you consult your doctor first, there should be no problem with you experimenting with it on your own to see how and if it works for you. At the end of the day, we're not calling anyone a liar, but facts are facts, so until there's more science-backed information on the subject, it's best to take any glowing tesimonials with a grain of salt.

To us, that meant any product with zero proven ingredients, case studies, or FDA clearance — which shrunk our list by a whopping 180 contenders. That’s right, there are only three treatments that have actually been cleared by the FDA and supported with clinical studies: finasteride (commonly marketed as Propecia), minoxidil, and laser treatments. And, since finasteride is prescription-only, it left us with two.

Yes. Hyperandrogenism, a medical condition characterized by excessive production of male hormones called androgens, can cause hair loss in affected women. The most common cause of hyperandrogenism in women is functional ovarian hyperandrogenism, also known as polycystic ovary syndrome. In addition to hair loss, other signs include obesity, acne, and irregular menstruation, and it is one of the most common causes of infertility.

First things first: If you're struggling with hair loss or thinning, you're far from alone. It's extremely common, with American women accounting for 40 percent of Americans struggling with hair thinning or loss. It also tends to be most prevalent in your 40s and 50s. This can occur for a laundry list of reasons, including hormonal changes, Alopecia, and stress, so it's always best to visit your doctor to determine what's going on. Regardless of the reason, losing your hair can be extremely devastating for some — make that most — people, seeing as hair is an external factor that can greatly impact a person's self-image and confidence. (Thanks for that, societal pressure.)

Men may also experience some sexual and emotional side effects while taking it: In a study published in the June 2011 issue of The Journal of Sexual Medicine, Dr. Michael Irwig of George Washington University found as many as 92 percent of test subjects reporting problems in the bedroom. The study also reported that “the mean duration of finasteride use was 28 months and the mean duration of persistent sexual side effects was 40 months,” meaning that side effects lingered long after subjects stopped taking the pill.
Instead, you may want to add vitamin D (about $15) to your shopping cart. A vitamin D deficiency can exacerbate hair thinning and make it almost impossible for any over-the-counter product to reverse hair loss, says Dhaval Bhanusali, a dermatologist in New York City, who recommends taking 5,000 international units of D3 a day (and it’s generally beneficial for bone health in women over 40). “There’s also a link between low iron and zinc levels and temporary hair shedding, called [telogen] effluvium,” says Rogers.
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."
