Key Takeaways:
-
A receding hairline is typically caused by male pattern baldness, but hormones, aging, lifestyle habits, medical conditions, and hair care practices can also contribute.
-
Genetics play the biggest role in determining your risk of hair loss, though the genes responsible can come from either side of your family.
-
Following a healthy diet, managing stress, avoiding smoking, and other healthy practices may support healthy hair growth.
-
Treatments like minoxidil and men’s hair growth vitamins may help slow hair loss and encourage new hair growth, depending on the underlying cause.
Most men have concerns about losing their hair. By your 30s, you may be keeping a close eye on your hairline or noticing thinning around your crown. Male pattern baldness becomes increasingly common with age, affecting an estimated 30 to 50 percent of men by age 50.
A receding hairline is the first sign of androgenetic alopecia or male pattern baldness. Most people think a receding hairline is inherited from your mother. That’s partially true, but it isn’t the whole story. Many factors play a role in your hair’s history, some of which you can control.
Genetics and Hereditary Factors
It’s well known that genes play a role in your receding hairline. The androgen receptor (AR) gene found on your X chromosome inherited from your mother is the culprit in blaming male pattern baldness on your mother. Androgens are male sex hormones and the AR gene determines your sensitivity to them. Men with this gene have around twice the risk of losing their hair than men without it.
However, hair loss involves more than one gene. There are 63 known genes that play a role in hair loss and only six of them are on the X chromosome.
Additionally, some studies show that you’re more likely to have hair loss if you are white, have African heritage, or are Asian. Studies show that if your father is bald, you’re 5–6 times more likely to lose your hair, too.
Hormonal Changes
Hair has a growth cycle that lasts 2–8 years. Typically after a growth cycle, your hair enters a resting phase for a few months, falls out, and is replaced by new hair.
Hormone changes can disrupt your hair’s growth cycle. Fluctuations in a sex hormone called dihydrotestosterone (DHT) contribute to hair loss. Too much DHT stimulation can speed up the hair growth cycle and delay regrowth, causing thinning or baldness.
Aging and Its Effects
Studies show that aging affects hair color, production, and fiber structure. Hair density peaks at age 25 and scalp coverage peaks at age 35. Lipid production, the natural oils that give hair its shine, softness, and smoothness, declines between ages 45–50.
As you age, your hair may also turn gray, becoming more sensitive to ultraviolet rays (UV) and can degrade the hair fibers, making hair look dull, thin, and frizzy.
In your 60s, you’re at higher risk for conditions that may cause hair loss. Fifty percent of men over 50 have some type of hair loss and 80 percent by age 80.
Lifestyle and Environmental Factors
Studies show your daily health habits can impact your hair loss.
-
Stress: Sudden or long-term physical or emotional stress can cause hair loss, a condition called telogen effluvium. Fortunately, the hair usually grows back once the stressful situation is resolved.
-
Smoking: Smoking has been linked to more severe male pattern baldness, and researchers believe it may damage hair follicles through inflammation, oxidative stress, and reduced blood flow.
-
Sleep: Poor sleep has been linked to several types of hair loss, including male pattern baldness. While researchers are still studying the connection, disrupted sleep may affect the hormones and biological processes involved in healthy hair growth.
-
Obesity: Some research suggests obesity may contribute to hair thinning by increasing inflammation and metabolic stress that can damage hair follicles, although more human research is needed.
-
Diet: Your hair gets nutrients from the food you eat. It's important to get enough healthy proteins, vitamins, minerals, and fats. A diet rich in these can help you keep your hair strong and healthy.
-
Sun exposure: Those highlights you get from being in the sun are actually weakened hair strands.UV rays can negatively impact your hair’s ability to absorb proteins and hold color.
Medical Conditions and Medications
Some medical conditions or their treatments can affect hair growth.
-
Thyroid Disorders: Severe or untreated thyroid disorders, including hypothyroidism or hyperthyroidism are strongly linked to hair loss. Fortunately, once the condition is controlled, the hair typically regrows.
-
Autoimmune diseases: Alopecia areata is an autoimmune disease that causes your immune system to attack hair follicles, causing you to lose hair from your head, eyebrows, or eyelashes, and is triggered by other autoimmune diseases, such as psoriasis, vitiligo, and thyroid diseases. Studies also indicate that people with asthma and atopic dermatitis have a higher risk of alopecia areata.
Chemotherapy is one of the best-known causes of medication-induced hair loss, but many other prescription drugs have also been linked to hair shedding:
-
Antifungals
-
Antiseizure drugs
-
Antidepressants
-
Beta-blockers
-
Blood thinners
-
Cholesterol drugs
-
Thyroid drugs
-
Steroids
-
Hormone replacement therapy
Hair often regrows after you stop taking the medication, but never stop taking a prescribed medication without first talking to your healthcare provider.
Hair Care Practices
The way you treat, style, and care for your hair can play a role in your hair health.
Tight hairstyles like braids or cornrows might result in traction alopecia or hair loss caused by tight pulling on the follicles. Excessive brushing can also be hard on hair.
Hot oil treatments or chemical perms and straighteners can reduce hair density and diameter, causing breakage. These can also cause scalp scarring which means permanent hair loss.
Hair dying and bleaching can also weaken the hair follicles, leading to breakage.
Preventative Measures and Treatments
Whatever the cause of your receding hairline, you can take actions to prevent or slow its progress.
First, to prevent hair loss and keep hair healthy:
-
Shampoo and moisturize your hair regularly.
-
Eat a healthy diet and protect your hair from exposure to sun and severe cold.
-
Treat any nutritional deficiencies and medical conditions.
-
Essential hair growth vitamins and minerals daily that should include recommended amounts of biotin or vitamin B7, vitamins D, E, C, A, zinc, iron, and selenium.7
Foundation Skincare’s Hair Serum stimulates hair growth at the follicle root and can make hair look fuller and thicker. Paired with UnTangled Hair Supplement, a hair supplement with the right amounts of vitamins, minerals, herbs, and acids you need to revitalize stagnant hair growth, can help your hair stay healthy and regrow. If you are concerned with hair loss, medical experts recommend taking two capsules a day to start and tapering to one capsule to maintain hair volume.
You can also talk to your doctor about preventive medications like minoxidil. These typically work while they are being used but hair loss resumes when you stop taking them.
The Bottom Line
A receding hairline, while common, isn’t a foregone conclusion. Taking care of your hair and consulting your doctor about the cause of your hair loss can help you understand the best way to prevent or treat your hair loss.
Here’s what we know:
-
Genetics aren't the only contributing factor. While inherited genes are the leading cause of male pattern baldness, hormones, aging, medical conditions, medications, and lifestyle habits can all influence hair loss.
-
Healthy hair starts with healthy habits. Eating a balanced diet, managing stress, avoiding smoking, and minimizing heat and chemical damage can help support stronger, healthier hair.
-
Early treatment may help preserve your hair. If you're noticing a receding hairline, check in with your healthcare provider about options such as minoxidil or other treatments that may slow hair loss and promote regrowth.
