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.
The bottom line. Hair grows back at a rate of about 6 inches per year. If your hair is falling out, talk with a healthcare professional so they can diagnose the cause of your hair loss.
Unfortunately, male and female pattern baldness is not reversible without surgical intervention. However, if detected early enough, certain medications, such as minoxidil, finasteride, and Dutasteride can help halt the progression of thinning hair.
In other cases, thinning hair is triggered by something going on inside the body — for instance, a thyroid problem, a shift in hormones, a recent pregnancy, or an inflammatory condition. Hair loss may also be genetic. The most common genetic condition is known as female-pattern hair loss, or androgenic alopecia.
Overview. Hair loss (alopecia) can affect just your scalp or your entire body, and it can be temporary or permanent. It can be the result of heredity, hormonal changes, medical conditions or a normal part of aging. Anyone can lose hair on their head, but it's more common in men.
Permanent Hair Loss:
When hair fall is triggered by predisposed genetic causes then the follicles are also affected and they miniaturize. This condition cannot be overcome without extensive hair treatment and this is termed as permanent hair loss.
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.
Generally, people begin noticing signs of hair loss in their 30s and 40s. More significant hair loss often happens when people reach their 60s and beyond.
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.
As people get older, their hair often starts losing volume and thickness. However, hair loss can also result from a health condition, nutrient deficiencies, stress, and other factors. Treatment can often help manage hair loss that occurs with aging by boosting hair health, thickness, and strength.
Signs of New Hair Growth
Identifying new hair growth is generally simple -- just look for new baby hair strands in the parts of your scalp that show visible thinning. Over the course of a few months, you might notice new hairs growing through your skin and starting to “fill in the gaps” in your hairline.
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.
Genetics
In women, hereditary hair loss usually starts after the age of 40. Roughly 40% of women have noticeable hair loss by the age of 50. And less than half of women get through life with a full head of hair. Hereditary hair loss looks a little different in women than it does in men.
When to see a doctor. See your doctor if you're concerned about how much hair you are losing every day. A gradual thinning on the top of your head, the appearance of patchy or bald spots on your scalp, and full-body hair loss are signs that there may be an underlying health condition.
What causes FPHL (Female Pattern Hair Loss)? Genes: Your family's genes can cause thinning of hair along the top of your head. Aging: Hormone changes as you age can cause balding. Menopause: This type of hair loss often gets worse when estrogen is lost during menopause.
Hair loss is when hair starts shedding from the root or when there is hair breakage from the scalp. Hair loss leads to hair shaft abnormalities and eventually, it leads to androgenic alopecia. If hair thinning over some time progresses, it may even lead to baldness.
It depends. “If a follicle has closed, disappeared, scarred, or not generated a new hair in years, then a new hair wouldn't be able to grow,” Fusco says. But if the follicle is still intact, yes, it is possible to regrow the hair—or to improve the health of the existing thinner hairs.
Is it reversible? While some forms of AFAB hair loss are temporary, female pattern baldness is permanent and irreversible without treatment. However, proper treatment can stop the hair loss and potentially help regrow some lost hair.
The three best types of extensions for this type of hair loss are clip-in extensions, sew-in weft extensions and tape-in extensions. If you are struggling with thin hair, you want to make sure you go to a registered hair extension stylist to create the best plan of action for you.
Cicatricial Alopecia. Cicatricial alopecia, also known as scarring alopecia, is a rare type of hair loss in which inflammation destroys hair follicles and causes scar tissue to form in their place. After scar tissue forms, hair doesn't regrow.
Telogen effluvium is generally reversible. A person with this condition does not lose all their hair, although it may become noticeably thin. Telogen effluvium is a form of hair loss characterized by hair thinning or an increase in hair shedding.
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.
