What causes baldness? Understand why people lose their hair

factors that cause hair loss

Effective for both male and female pattern baldness, application of Rogaine (topical minoxidil) on the scalp can spur hair regrowth. For males, 2% or 5% concentrations work, while for females, 2% is recommended. You will need to use this treatment indefinitely; if you stop, you will lose the regrown hair. Both men and women develop this type of hair loss, which is the most common cause of hair loss worldwide. Regardless of whether it develops in a man or women, the medical term is androgenic alopecia.

How can I prevent hair loss?

Healthcare providers refer to age-related hair loss as "senescent alopecia," which differs from male pattern hair loss. Researchers have observed hair mild follicle shrinkage, resulting in thinner individual hair strands. Menopause, when the menstrual cycle stops, causes changes in estrogen and testosterone—hormones involved in regulating the hair cycle. Typically setting on when women are between 45 and 55, these fluctuations can trigger female pattern hair loss. Baldness typically refers to excessive hair loss from your scalp.

Depending on the underlying cause of hair loss, this condition may or may not be reversible. Some medicines can prevent hair loss or spur growth, making proper diagnosis critical. In this respect, it can be seen as a viable treatment option in androgenetic alopecia [102].

Acid Reflux Drugs May Heighten the Risk of Migraine Attacks and Severe Headaches

Sometimes, your hair will regrow on its own, making treatment unnecessary. “Blocking the newly discovered muscle and its contraction cannot cure baldness caused by hair loss diseases,” emphasizes Dr. Michael Rendl, who was the senior author of the study. They found that in the absence of circulating corticosterone, the stem cells underwent many more rounds of regeneration during the animals’ lifetime.

Nutrients play important roles in hair follicle development and immune function. Having protein, vitamin, and mineral deficiencies in the diet can put people at greater risk of alopecia. Immune cells may become overactivated, leading to hair loss in band-like patterns. Scarring tissue replaces the affected hair follicles, and the hair does not grow back. Excessive brushing or prolonged tension can damage the hair, causing traction alopecia.

Pregnancy, and especially giving birth, can lead to hair loss. You're most likely to see hair loss about 3 months after giving birth. If you're losing hair while pregnant, ask your doctor if you might have a dietary deficiency.

What’s The Most Common Cause Of Female Hair Loss?

Yes, treating the thyroid disease can reverse the hair loss. No matter which term you use, it means that you’ve inherited genes that cause your hair follicles (what each hair grows out of) to shrink and eventually stop growing hair. Shrinking can begin as early as your teens, but it usually starts later in life. A dermatologist is a medical doctor who specializes in treating the skin, hair, and nails. Telogen effluvium is a type of sudden hair loss that results from emotional or physical shock, like a traumatic event, period of extreme stress, or a serious illness. Finasteride inhibits 5 alpha-reductase, blocking the conversion of testosterone to dihydrotestosterone (DHT), the androgen responsible for male pattern baldness.

Effective treatment for hair loss begins with finding the cause. To get an accurate diagnosis, it helps to see a board-certified dermatologist. These doctors have in-depth knowledge about the many causes of hair loss and experience treating the diverse causes.

Which vitamin can help with hair loss?

Common types of hair loss are androgenetic alopecia, telogen effluvium, anagen effluvium, tinea capitis, and alopecia areata. Regrowth continues for over a year, after which time it stabilizes. Minoxidil usually needs to be used long-term to prevent hair loss and promote hair growth.

See your dermatologist if you notice this type of hair loss. The sooner you start treatment, the better the chances for hair regrowth. Certain conditions, including anagen effluvium and alopecia areata, can cause hair to fall out suddenly. People should speak with a doctor to identify the cause of sudden hair loss. Depending on what’s causing your hair loss, it may be temporary or permanent. Treatments can help people with certain types of hair loss.

Female pattern baldness causes more diffuse (widespread) thinning and is generally more gradual in its progression, whereas in men, pattern baldness causes partial or complete hair loss. It has been reported that hair loss and depigmentation are seen in hair and eyebrows in people affected by linoleic acid and alpha-linolenic acid deficiency [83]. Mice with testosterone-induced alopecia showed a significant increase in hair growth after day 16 of topical applications of hydroalcoholic extracts of rosemary, which is a polyphenol. In vitro tests showed strong inhibition of the 5AR enzyme binding to the dihydrotestosterone (DHT) receptor [98, 99].

It can be helpful to keep a hair diary to track any changes you notice or symptoms you experience and to look for patterns. Folate is essential for cell division and maintenance, and for synthesis of the nucleotide (thymidine), which is required for DNA repair. Folate also plays an important role in the ‘site-specific’ methylation of the cytosine base in gene expression. Remethylation of plasma homocysteine to methionine is another action of folate/folic acid.

If you suspect you may have this mental health condition, there are treatments that can help, such as cognitive behavioral therapy and habit reversal training, notes the Mayo Clinic. These types of therapies can help you be more cognizant of urges to pull your hair, and help you develop other coping mechanisms instead. Additionally, while no medications are approved for trichotillomania alone, certain antidepressants or antipsychotics may help. Some people may experience excessive hair loss shortly after giving birth. This type of hair loss is a temporary condition and usually resolves within a year or sooner.

Other vitamins and minerals may also play a role in hair loss. People can speak with a healthcare professional to determine whether they have a vitamin deficiency that may be causing hair loss. A 2018 review suggests that a vitamin D deficiency may link to hair loss. The authors also suggest that to help prevent hair loss, people low in iron would benefit from iron supplementation and making sure they get enough vitamin C. People may experience hair loss while using birth control pills.
