Pregnancy may cause many changes in the scalp hair. As the hormones fluctuate during pregnancy, a large number of women feel their hair thickens and becomes fuller. This may be related to change in the number of hairs cycling in the growth phase of hair growth, but the exact reason is unknown. Quite often, there may be a loss of hair (telogen effluvium) after delivery or a few months later which will eventually normalize.
Finasteride inhibits an enzyme that converts testosterone to DHT, or dihydrotestosterone, the hormone that causes hair loss in men, and unlike minoxidil, this drug can actually help hair grow back, as well as prevent further loss. All you have to do is take one pill a day, and according to Dr. Evan Rieder, dermatologist in the Ronald O. Perelman Department of Dermatology at NYU Langone Health, two-thirds of men taking this treatment will see improvements in hair density over time.
Men’s Rogaine Extra Strength Solution is the liquid version of our top pick. It didn’t make our final cut because it includes propylene glycol, which causes irritation in roughly one-third of its users. With that said, Dr. Wolfeld finds that it can be even more effective in practical daily use. In his experience, “the solution can penetrate and get into your scalp a little bit better” than the foam — especially if you’re not taking the time and effort to apply the foam correctly. This seems crazy to us since the foam so quickly dissolved into a liquid in our tests, but if you’re worried, try a one-month supply of the liquid and make the switch to foam if you notice any irritation.
DR. WRIGHT: If stomach acid is low, protein isn’t efficiently digested – and hair and nails are made up of… protein! If we are deficient in protein, our bodies know that we can live without hair or nail proteins, but we can’t survive without heart muscle proteins or other important body proteins. So if we are short in supply of protein, the hair or nails are the first to go.
When men have hereditary hair loss, they often get a receding hairline. Many men see bald patches, especially on the top of the head. Women, on the other hand, tend to keep their hairline. They see noticeably thinning hair. The first sign of hair loss for many women is a widening part. In rare cases, men see noticeably thinning hair. And in rare cases, women can see a receding hairline or bald patches. The reasons for this are unknown.
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.
These medicines slow thinning of the hair and increase coverage of the scalp by growing new hair. They also thicken the shafts of your existing hair so that it grows in thicker. If you stop using the medicine, any hair that has grown in will gradually be lost. Within 6 to 12 months after you stop using the medicine, your scalp will most likely look the same as it did before treatment.
When hair loss is related to a medication, stopping the drug usually prevents further hair loss, and the hair will eventually grow back. Hair also tends to grow back after most illnesses, radiation therapy, or chemotherapy. Wearing a wig or hat can hide the hair loss until the hair returns. Hair transplants are a more permanent hair-replacement solution.
Initially used to treat high blood pressure, minoxidil was the first medication approved by the FDA to treat male pattern baldness. By applying Rogaine (or a generic version) directly to the scalp twice a day, a man in the early stages of hair loss can often stimulate growth. The American Hair Loss Association points out that results of treatment with minoxidil are limited, but it still endorses using it in combination with other treatments or as an alternative if finasteride doesn't work.
My hair began to thin when I was 28 years old. Now I am 44 and the top of my head is bald. Recently, I considered using medicine to treat my hair loss and see if any hair would regrow. After reading the literature and talking to my doctor, I decided not to take medicine because it is unlikely to make a huge difference in my hair—and I don't want to take medicine forever!
Alopecia areata: Researchers believe that this is an autoimmune disease. Autoimmune means the body attacks itself. In this case, the body attacks its own hair. This causes smooth, round patches of hair loss on the scalp and other areas of the body. People with alopecia areata are often in excellent health. Most people see their hair re-grow. Dermatologists treat people with this disorder to help the hair re-grow more quickly.
Other medical conditions — most commonly telogen effluvium and seborrheic dermatitis — can also cause hair loss, but most people can trace their follicular woes back to androgenetic alopecia, so we focused our search there. We started with more than 200 products, including all-natural solutions and high-tech gadgets, while skipping treatments that focus only on volumizing or thickening hair. We also limited our scope to the scalp, and left out specialty products designed only for eyebrows or beards.
Evidence suggests that two thirds of men who take finasteride (either Propecia or its generic form) will benefit from renewed hair growth. Finasteride halts hair loss for the majority of men who use it, and more than 90% of our hair loss patients see desirable results. Men normally need to take finasteride for at least 3 months before any effect is seen, and the balding process will usually resume if treatment is stopped.
The HairMax Ultima 12 LaserComb ($395) makes for a great addition to any hair loss regimen — provided you can afford it. Dr. Wolfeld notes that it’s a popular option in his practice. “Some people like the action of combing something through their hair,” he says. “They find that to be a little bit easier to do as part of their routine in the morning.” Dr. Khadavi also recommends using a laser treatment of some kind in conjunction with other treatments. “Lasers do help in stimulating the hair into the growth phase. We don’t know the exact mechanism of how it works, but it definitely helps.”
