Finasteride slows the rate of hair loss and stimulates new hair growth by inhibiting the body's production of a hormone that destroys hair follicles. This medication is taken once a day by mouth and is most effective when taken at the same time each day.
Injections of corticosteroids: To help your hair regrow, your dermatologist injects this medication into the bald (or thinning) areas. These injections are usually given every 4 to 8 weeks as needed, so you will need to return to your dermatologist's office for treatment.
Only riboflavin, biotin, folate, and vitamin B12 deficiencies have been associated with hair loss.
Minoxidil. Minoxidil (Rogaine) is the only drug approved by the Food and Drug Administration (FDA) to treat female pattern baldness. It's available in 2% or 5% formulas. If possible, opt for the 5% formula — older studies found that it's superior.
A dermatologist may recommend topical minoxidil, which is also available over the counter. A doctor might also prescribe oral finasteride for men. These medications are FDA-approved for certain conditions that cause hair loss. Other prescription medications may be available as an off-label use for hair loss.
Biotin. Biotin, also known as vitamin B7, is a complex B vitamin that is often touted for having hair growth benefits. And some of that hype may actually be worth it. Biotin has functions in “creating red blood cells, which carry oxygen and nutrients to the scalp and hair follicles,” says Dr. Green.
Lifestyle factors could include using certain hair products, wearing your hair up too tightly, experiencing high stress levels, or not getting enough of certain vitamins and minerals in your diet. People who have immune system deficiencies could also have thinning hair.
Family history (heredity). The most common cause of hair loss is a hereditary condition that happens with aging. This condition is called androgenic alopecia, male-pattern baldness and female-pattern baldness.
The only medicine approved by the United States Food and Drug Administration (FDA) to treat female pattern baldness is minoxidil: It is applied to the scalp. For women, the 2% solution or 5% foam is recommended. Minoxidil may help hair grow in about 1 in 4 or 5 of women.
Sources of Biotin
Foods that contain the most biotin include organ meats, eggs, fish, meat, seeds, nuts, and certain vegetables (such as sweet potatoes) [2,12].
How much B12 should I take daily for hair growth? The lowest amount recommended that should be traceable in your body is 2.4 mcg. While you are looking for a difference in your hair growth you can increase this dosage to 3 mcg and beyond.
The study found that those who were given Viviscal showed significant growth along with hair shine and skin smoothness. “The oral supplement assessed in this study safely and effectively promotes significant hair growth in women with temporary hair thinning,” the study concluded.
For one good biotin supplement, Dr. Jaliman recommends Nature's Bounty Biotin. Containing a marine complex, as well as biotin, zinc, vitamin C, iron, and horsetail extract, Viviscal “uses vitamins to extend the anagen (growth) phase of the hair growth cycle,” says Dr. Engelman.
There are a wide range of conditions that can bring on hair loss, with some of the most common being pregnancy, thyroid disorders, and anemia. Others include autoimmune diseases, polycystic ovary syndrome (PCOS), and skin conditions such as psoriasis and seborrheic dermatitis, Rogers says.
Here's the hard truth: Little can be done to permanently change the diameter of individual hair strands. Thickening products can do wonders to temporarily plump hair strands, but when it comes down to it, fine hair is genetic and can't be changed.
Possible causes of hair loss include stress, poor diet, and underlying medical conditions. Everyone experiences hair shedding, and it happens to each of us every day. Most people lose 50 to 100 hairs per day as part of this natural cycle, more on days you wash your hair.
Sudden hair loss is typically a sign of two conditions: telogen effluvium or alopecia areata. Telogen effluvium is commonly caused by stress, which increases the natural rate of hair loss. Alopecia areata is an autoimmune condition that causes your body to attack its hair follicles, resulting in hair loss.
