Sometimes simply addressing a medical condition prompting hair loss will be enough for the hair to regrow. In other instances, a woman might consider a medication like minoxidil (Rogaine), which helps with certain types of hair loss, or another treatment to replace or regrow lost hair.
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.
Here's the truth: You can't change the size of your hair follicles. If you were born with fine hair, it's genetics, and no product will completely alter that. Of course, there are ways to maintain your hair health, add volume, and keep it from getting any thinner.
Thinning hair can grow back depending on what caused it to thin in the first place. People who experience thinning hair due to nutrient deficiencies, stress, pregnancy, and other nongenetic reasons could experience regrowth. If you're experiencing new hair loss or hair thinning, it's best to consult your doctor.
It'll take at least six months of treatment to prevent further hair loss and to start hair regrowth. It may take a few more months to tell whether the treatment is working for you.
Telogen hair, or 'resting' hair, comprises around 15% of the hair on a person's scalp. Periods of elevated stress can lead to this hair being temporarily lost, contributing to a visibly thinner scalp and hairline.
The bottom line. There's no strong evidence to support using biotin for hair growth or to prevent hair loss in people without a deficiency. Because hair thinning and poor hair growth are sometimes associated with a biotin deficiency, correcting a deficiency can help restore hair growth in some people.
"Sudden thinning hair can be a symptom of anemia (low red blood cell count), hormonal issues especially related to events like pregnancy, or a thyroid disorder, which are all very common in women," says Dr. Peredo.
As with male pattern baldness, female pattern baldness comes from hormone imbalances, specifically dihydrotestosterone imbalances, or DHT. This hormone is similar in structure to testosterone, but it is significantly more potent [3]. DHT can attach to receptors on the hair follicles, causing the follicles to shrink.
The answer is yes! Fortunately, unlike genetic hair loss, most hair loss caused by hormonal imbalances is reversible.
If left untreated, the hair follicles will slowly become smaller and smaller until they eventually die and hair loss is permanent.
The hair loss is temporary, and should return to its pre-effluvium density, although this process is generally slow. It can take months (but generally less than 6) before the shedding stops, and then months to years for lost hair to grow back at the sluggish rate of ~½ inch per month.
Fine or thin hair: "Fine hair will need to be shampooed as often as every other day to provide it with the moisture it needs to flourish and grow," Courtney says. Cleansing also helps remove buildup and oils that can weigh fine or thin hair down.
With a few precautions, coloring thinning hair can be safe -- and may even protect the hair shaft from breaking. There's a myth that permanent hair-color is damaging, but that's only true if you bleach your hair or if you use the color incorrectly.
How Many Washes Should You Aim For? While this question truly depends on the nature of your hair and varies from every person, if you have thinning hair, try to wash your hair between 3-4 times a week if necessary; washing thinning hair just 3 to 4 times per week means doing so just about every other day.
