Some women find that the minoxidil solution leaves a deposit that dries and irritates their scalp. This irritation, called contact dermatitis, is probably caused not by the minoxidil itself, but rather by the alcohol that is included to facilitate drying. A 5% solution (available only by prescription and approved only for men) is more effective than the 2% formulation and may be prescribed off-label for women. The 5% version comes in a foam, which appears to cause less irritation than the liquid.
In-office laser light treatments or at-home handheld devices, such as the HairMax LaserComb, supposedly grow new hair by stimulating blood flow to the area (think: an amped-up version of a scalp-stimulating shampoo). Just don’t expect the device to make your noggin go from looking like George Costanza’s to Jerry Seinfeld’s. “These lasers won’t grow any new hair. If anything, they may just help you hang on to some of the hair that you already have a bit longer,” says Dr. Joyce.
Although unwanted hair growth has been reported on the face and on other parts of the body, such reports have been infrequent. The unwanted hair growth may be caused by the transfer of minoxidil topical solution 2% to areas other than the scalp, or by absorption into the circulatory system of low levels of the active ingredient, or by a medical condition not related to the use of minoxidil topical solution 2%.
Not surprisingly, treatments with 5 percent minoxidil work better than treatments with 2 percent minoxidil. A randomized clinical trial published in the American Journal of Clinical Dermatology in 2002 found that, in men with androgenetic alopecia, “5 percent topical minoxidil was clearly superior to 2 percent topical minoxidil and placebo in increasing hair growth.” The difference was actually pretty astounding — after 48 weeks, the men who used 5 percent minoxidil experienced 45 percent more hair growth than the men who used the 2 percent treatment.
The other main hair-loss treatment that was recommended by all four dermatologists I interviewed is finasteride, often called by its brand name Propecia. This FDA-approved medication is only available with a prescription, but these days, it’s found as a generic and ordered online after a virtual consultation, through start-ups like Hims, Keeps, and Lemonaid.
If a pregnant woman comes in contact with crushed or broken Finasteride tablets, wash the contact area right away with soap and water. If a woman who is pregnant comes into contact with the active ingredient in Finasteride, a healthcare provider should be consulted. If a woman who is pregnant with a male baby swallows or comes in contact with the medicine in Finasteride, the male baby may be born with sex organs that are not normal.
"Others are taking hair follicles out of human scalp and growing them with dermal papilla cells," Cotsarelis says. "If they grow in culture, you might be able to recombine them with skin cells and form new follicles. This would let you expand the number of follicles you get for a hair transplant. This may not be that far off -- five to 10 years, maybe. There's very good evidence you will be able to do that."
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.

I will write more later, but this morning, I confirmed that YES this is working. It's totally working. I have new growth all over the "test" area (I was afraid of the dread shed) where I was using it. It's been about 6 weeks. The growth is healthy--these are thick, normal hairs. I tried a bunch of natural stuff before this. I was freaking out, thinking there were wigs in my future. My hair is still falling out a lot, but to see regrowth is such an incredible relief. I just want to put this out there to everyone who is struggling with hair loss, for whatever reason--i don't care what the studies say--this is abundant regrowth. And it's definitely from the romaine. Not crazy about putting chemicals on my head every day, but the stress and worry about my hair was almost definitely more toxic than whatever is in this. No side effects that I've noticed.

For as long as men have been fretting over their expanding foreheads, they've been scrounging for hair loss treatments. From hippo fat pomades to the urine of young foals, history is full of just-so-crazy-they-might-work concoctions. They didn’t work. And a quick Googling reveals that most of the products and services marketed today are only slightly less absurd.
Cimetidine, brand name Tagamet, belongs to a class of histamine blockers used mainly to treat gastrointestinal ulcers. The histamine-blocking action prevents the stomach from producing excess acid, allowing the body to heal the ulcer. Cimetidine also has a fairly powerful anti-androgenic effect and has been shown to block dihydrotestosterone from binding the follicle receptor sites.

Even though modern folklore, and even some limited scientific studies, have suggested that the mother's side of the family is largely responsible for a genetic predisposition toward baldness, the truth is balding is not all our mothers' fault. In fact, doctors now say baldness patterns are inherited from a combination of many genes on both sides of the family. There are some environmental factors that come into play, too.
