Hair loss in men is a common issue that affects a significant percentage of the male population. It can be a frustrating and distressing experience, and many men may feel self-conscious or embarrassed about their hair loss. Understanding the causes of hair loss in men can help find the proper treatment or solution to restore or maintain healthy hair growth. In this blog post, we will explore the various causes of hair loss in men and the available options for treatment and prevention.
Most Common Causes of Hair Loss in Men
Androgenetic Alopecia (AGA)
Androgenetic alopecia (AGA), known as male pattern baldness, affects 30 to 58 percent of men over 50. It is the most common cause of hair loss in men. AGA is caused by a combination of genetic and hormonal factors, and it typically affects men with a family history of hair loss.
AGA is characterized by a receding hairline and thinning of hair on the crown, which eventually leads to complete baldness. The condition is caused by an enzyme called 5-alpha reductase, which converts testosterone into dihydrotestosterone (DHT). DHT is a hormone that causes hair follicles to shrink, leading to hair loss.
Dihydrotestosterone (DHT) is a hormone that plays a key role in male pattern baldness. DHT is a byproduct of the male hormone testosterone, and it attaches to the hair follicles on the scalp, causing them to shrink. As the hair follicles shrink, they produce thinner and weaker hair, eventually leading to hair loss. DHT, the main cause of hair loss in AGA, acts by inducing the production of interleukin (IL-) 6 and transforming growth factor (TGF-) β2 by dermal papilla cells (DPCs). Therefore, it suppresses hair growth and premature initiation of the catagen phase (Umar S et al., 2021).
Less Common Causes of Hair Loss in Men
Telogen effluvium is a temporary hair loss condition due to a change in the hair growth cycle. Stress, hormonal changes, nutrient deficiencies, or certain medications can cause it. During the telogen phase, hair is in a dormant state, and it eventually falls out. In individuals with telogen effluvium, the hair growth cycle is disrupted, and more hair falls out than usual, leading to hair loss. The most common treatments for telogen effluvium include addressing the underlying cause, reducing stress, and ensuring proper nutrition. In some cases, minoxidil may be recommended to stimulate hair growth.
Nutritional deficiencies can also cause hair loss. A diet deficient in specific vitamins and minerals, such as iron, zinc, and vitamin D, can lead to hair loss. Inadequate protein intake can also cause hair loss. The most common treatment for hair loss due to nutritional deficiencies is to supplement the diet with the lacking nutrients, such as iron, zinc, or vitamin D supplements. A balanced diet rich in essential nutrients can also help promote healthy hair growth.
Scalp infections, such as fungal or bacterial infections, can cause inflammation of the hair follicles, leading to hair loss. The most common treatments for hair loss due to scalp infections include topical or oral antifungal or antibacterial medications to eradicate the disease. Once the infection is treated, hair growth should resume.
Certain medications can also cause hair loss as a side effect. Medications used to treat conditions such as high blood pressure, depression, and gout can cause hair loss. The most common treatment for hair loss due to medication is to consult with a healthcare professional about potentially changing the medication or adjusting the dosage. Sometimes, hair loss may resolve once the medication is stopped or modified.
Male pattern hair loss is influenced by the levels of testosterone and DHT, and weightlifting can increase testosterone levels. However, the primary cause of male pattern hair loss is a genetic predisposition, with a natural increase in testosterone and DHT. Although weightlifting can lead to a slight rise in these hormones, it is not expected to cause additional hair loss.
That being said, individuals who use testosterone or other steroids for bodybuilding can indeed affect the hair on their head and body in several ways:
1. Androgenic Alopecia: Anabolic steroids can trigger androgenic alopecia, commonly known as male pattern baldness. A receding hairline and thinning of hair on the crown of the head characterize this condition. It is more common in individuals with a genetic predisposition to hair loss.
2. Accelerated Hair Loss: Steroids can expedite hair loss in individuals prone to androgenic alopecia. If someone has a family history of baldness, the use of steroids can exacerbate the condition and lead to quicker hair thinning.
3. Excessive Body Hair Growth: In some cases, steroid use can cause hirsutism, which is excessive hair growth on the body, including areas where hair growth is typically minimal in both men and women.
4. Changes in Hair Texture: Some users may notice changes in the texture of their hair while taking anabolic steroids. It might become coarser, drier, or more brittle.
5. Temporary Hair Shedding: Anabolic steroids can trigger a condition called telogen effluvium, leading to temporary hair shedding. This occurs when a large number of hair follicles enter the resting phase simultaneously due to the hormonal changes induced by steroids.
It's important to understand that the impact of steroids on hair can vary from person to person. Not everyone who uses steroids will experience significant hair loss or changes in hair growth patterns. Still, those genetically susceptible to hair loss are more likely to be affected.
Stress can disrupt the hair growth cycle and trigger telogen effluvium. Stress can also cause an increase in the levels of hormones such as cortisol, which can lead to hair loss. The most common treatments for stress-related hair loss include stress management techniques, such as meditation, exercise, or therapy, and ensuring adequate sleep and nutrition.
Environmental factors such as pollution, UV radiation, and exposure to harsh chemicals can damage the hair follicles and lead to hair loss. The most common treatments for hair loss due to environmental factors include reducing exposure to harmful elements, using gentle hair care products, and protecting the hair and scalp from sun damage. Incorporating hair-protective measures, such as wearing a hat or using hair sunscreen, can help minimize the impact of environmental factors on hair health.
Alopecia areata is an autoimmune disorder that occurs when the immune system attacks the hair follicles, causing hair loss. Alopecia areata can cause hair loss on the scalp and other body areas.
The most common treatments for alopecia areata include corticosteroid injections, topical immunotherapy, and oral medications, such as corticosteroids or immunosuppressants, to suppress the immune system's attack on hair follicles. In some cases, light therapy may also be recommended to help stimulate hair regrowth.
What are the Best Treatments for Male Pattern (Androgenetic) Hair Loss?
Finasteride is a medication that is commonly used to treat male pattern baldness. It works by inhibiting the enzyme 5-alpha reductase, which converts testosterone into DHT. By reducing the levels of DHT, finasteride can help to prevent hair loss. Oral finasteride may cause a range of adverse effects in some individuals, including sexual side effects like reduced libido, erectile dysfunction, and ejaculation disorders. Other potential side effects include mood changes, such as depression and anxiety, as well as breast tenderness or enlargement. It is important to note that while these side effects may occur, they are not experienced by all users, and many people take finasteride without issue.
Topical minoxidil 5% is an FDA-approved treatment for male pattern hair loss, offering a non-invasive solution for many individuals. This over-the-counter medication stimulates hair growth and can be effective for various stages of hair thinning. Some possible side effects of minoxidil include skin irritation, itching, and redness.
