Finally, if these tests come back normal, your dermatologist may suggest a scalp biopsy of a couple of two-millimeter sections taken from your scalp under local anesthesia ($400 and up). It can determine whether genetic hair loss, telogen effluvium (a condition in which hair falls out from stress or rapid weight gain), or a disease (such as lupus) is the cause of your shedding, and your dermatologist can treat you accordingly.
Sure, you can easily pop a hair growth supplement, but honestly, the word's still out on whether or not they're an effective way to help your hair grow faster. Plus, they can contain unnecessary large amounts of minerals and vitamins (ahem, biotin) which can actually wreak havoc in other ways (ahem, breakouts). Thus, eating your way to longer hair is actually a smarter, nutritionist-approved way to make your hair grow faster. Vitamins and minerals occurring naturally in foods are easier for your body to utilize, and they'll naturally deliver a healthier ratio of nutrients—just the way Mother Nature intended. 
Results from clinical studies of mostly white women ages 18 to 45 years with mild to moderate degrees of hair loss report that after using minoxidil for eight months, 19% of users had moderate regrowth and 40% had minimal regrowth. Of those using a liquid without active minoxidil (a placebo) during the same time period, 7% reported moderate hair regrowth while 33% had minimal regrowth.
Also new is the HairMax Laser Comb. It's a red light therapy hairbrush-like device that increases circulation and the biological march that makes hair. It's only approved in men (though some women are using it) and in my experience, is not as good as minoxidil. But in one study, 45% of users reported improvement after eight weeks, and 90% saw improvement after 16 weeks.
Though, it is important to point out that a lot of these companies are developing procedures that involve implanting hair, which means there is a chance they will be expensive — as we mentioned before, traditional hair transplants are costly. But a few companies and products such as Follicum’s FOL-S-005 and Fidia Pharma’s Brotzu Lotion are being designed as topical treatments.
Both minoxidil and finasteride require a lifelong commitment, but for users looking for a treatment with permanent results, hair transplant surgery may be the solution. Over the years, surgeons have developed techniques to deliver natural-looking results that are a far cry from early hair transplants, which had a cornrow-like appearance. These procedures are costly and may require multiple sessions depending on the patient.

The majority of American men and women are affected by hair loss, known as alopecia, at some point in their lives, according to experts. Androgenetic alopecia (AGA), commonly referred to as male- or female-pattern baldness, accounts for about 95 percent of hair loss in the U.S., according to Better Nutrition magazine. Experts say pattern baldness is genetic and inherited equally in men and women. However, the hair-loss gene can only express itself when dihydrotestosterone (DHT), a male hormone, is present. Because estrogen usually suppresses male-hormone production, women don't typically experience pattern baldness until after menopause has begun; although, even the slightest hormone shift can cause hair loss in women.


"I recently started using your hair growth products, and now there is no looking back. My hair has always been really thin and fine and growth around the hairline at the temples has been poor. It almost looked like my hairline was receding. I didn't like putting my hair up as I looked like I was going bald. But, not any more. My hair feels thicker, and growth is improving at the temple area. My hair would never grow beyond my shoulders, that's going to be the next test, how long will it grow!! Thank you, after years of irritation with my fine hair things are looking up."
