Noticing your hairline receding or hair thinning on top? Male pattern hair loss is very common, affecting around 50 million men in the United States. If you're beginning to see signs of hair loss, understanding treatment options to stop progression and enhance hair regrowth is important. Read on for information from dermatologists on tackling male pattern hair loss.
What is Male Pattern Hair Loss?
Male pattern baldness, also called androgenetic alopecia, is an inherited form of hair loss stemming from genetics and male sex hormones like testosterone and DHT. It follows a pattern of receding hairline and hair thinning at the crown, ultimately leaving behind only a rim of hair if left untreated.
Male pattern baldness can begin any time after puberty, often becoming noticeable for the first time in your 30s or 40s. But early prevention and treatment are key - because once those hairs fall out, they’re less likely to grow back over time.
Who Typically Gets Male Pattern Baldness?
If you have close male relatives who lost hair following the same pattern, you have an increased risk of male pattern baldness since genetic factors are at play. However, lifestyle and hormonal influences also contribute to hair loss progression.
In the average population:
50% of men begin experiencing hair loss around age 50
50 million men in the United States currently have male pattern baldness
1 in every 4 men start by age 30 years old
Early prevention measures and medical therapy offer the best ability to slow hair loss once you notice thinning or a receding hairline start developing.
What Causes Male Pattern Baldness?
The exact triggers causing miniaturization of your hair follicles are not fully understood. However, it’s known dihydrotestosterone (DHT) - a hormone byproduct of testosterone - accumulates around hair follicles in the scalp, contributing to shedding and decreased regrowth. Enzymes, genes related to androgens and aging may also play a role.
In a normal hair cycle, about 85% should remain in the growing phase while 15% rest or shed. In male pattern loss, more shift to the rest/shed phase, cutting down your viable overall hair volume long term.
How do Dermatologists Diagnose the Cause of Hair Loss?
Dermatologists conduct a full history, physical and microscopic exam to determine what's causing your hair loss. They evaluate:
Pattern and rate - where and how rapidly is hair thinning
Family history of balding
Diet, medications or illnesses that could contribute
Signs of inflammation/scaling we see microscopically
For male pattern hair loss, surrounding hair should still feel soft and look healthy - just thinner - whereas inflammatory conditions like alopecia areata cause patchy smooth bald areas. Exploring contributing factors helps guide appropriate treatment.
What Medical Treatment Options Work Best Against Male Pattern Hair Loss?
The two medications holding FDA approval for regrowing hair in male pattern baldness include:
Minoxidil Solution - Brand name Rogaine
Applied directly to balding areas twice daily
Promotes hair regrowth and scalp health
Works by improving blood flow and prolonging growth phase
Liquid Solution - Better for Dry Scalp
Foam Version - Better for Oily Scalp
Finasteride – Brand names Propecia or Proscar
Oral tablet taken once daily
Blocks DHT to hinder further loss and encourage new growth
Regrows 30% more hair in 3-4 months per clinical trials
Dutasteride is another 5-alpha reductase inhibitor that stops your body from converting testosterone into DHT. Dutasteride seems to work equally well in trials, but isn't FDA approved for hair loss. Some of the literature even suggest dutasteride to be superior.
These medications are most effective when used together - providing both hair stimulating and DHT-blocking mechanisms for synergy. Studies show the combo grows about 40% more hair than minoxidil alone.
Over 60% of men maintain or regrow hair with medical treatment over long-term use when started sufficiently early at the first signs of balding.
What are Possible Side Effects of These Male Pattern Hair Loss Medications?
While topical minoxidil solution tends to be well tolerated overall with minimal systemic absorption - oral finasteride, dutasteride and sometimes topical finasteride or oral minoxidil can cause potential sexual side effects in a small percentage of men. These may include:
Erectile dysfunction (oral finasteride, oral dutasteride)
Decreased libido (oral finasteride, oral dutasteride)
Reduced ejaculate volume (oral finasteride, oral dutasteride)
Leg swelling (oral minoxidil)
Excessive hair growth elsewhere (topical and oral minoxidil)
Cardiac effusions (swelling around the heart) - (oral minoxidil)
For most however, sexual side effects remain uncommon and often resolve spontaneously despite continued treatment. Plus, cessation returns most symptoms to normal. Discuss all risks/benefits with prescribing physicians.
What About PRP Injections for Regrowing Hair?
A newer treatment category called PRP (platelet rich plasma) has emerged as another option for restoring hair growth. It involves multiple tiny injections of your own PRP containing growth factors derived from a blood sample into balding areas of the scalp.
PRP is thought to stimulate dormant hair follicles for improved regrowth. Some dermatologists also provide PRP with microneedling to enhance scalp penetration. Studies have shown PRP injection treatments can improve hair counts for both men and women suffering pattern hair loss.
Potential advantages include:
Non-drug, natural approach
Complementary to existing meds like minoxidil or finasteride
In-office procedures every 1-2 months for the first half year, followed by a maintenance schedule
Downsides are cost since it’s often not covered by insurance and the need for repeat visits. Maintenance treatments are required to sustain benefits similar to traditional medications.
What About Possible Side Effects of PRP Injections Themselves?
Because PRP therapy utilizes injection of your own concentrated growth factor-containing plasma - risks inherent to the injections themselves can occur but serious reactions are rare. These may potentially involve:
Mild swelling, redness and pain at injection sites
Low grade headache
Dizziness
Infection at graft sites (uncommon with proper technique)
Any symptoms should resolve quickly within 1-2 days however.
What About Hair Transplants for Restoring Hairlines?
Surgical hair transplant techniques like follicular unit extraction (FUE) transplant have also become very advanced – allowing smooth hair redistribution from the back/sides to any thin areas upfront or on top. Skilled surgeons create a natural appearance by angling and aligning new grafts properly.
Many patients with adequate donor hair choose medical therapy like Rogaine/Propecia first to stabilize ongoing loss - then get transplants later to restore peaks and hairlines for fullness. Other men jump straight to hair transplants first. Discuss all options thoroughly with your providers.
Do Specialized Supplements or Shampoos Really Work for Hair Loss?
Despite prolific marketing claims and compelling testimonials promoting everything from expensive anti-hair loss vitamins to cleansing shampoos - quality peer-reviewed evidence substantiating major efficacy is currently still lacking.
Could they contribute some mild improvement? Possibly a small amount in a subgroup by optimizing general scalp health. But outcomes are unreliable and generally underwhelming for the high costs often charged.
Nizoral anti-dandruff shampoo is an exception and may help reduce scalp inflammation and actually increase the cumulative hair diameter in some studies, but won’t revive dying follicles without adding stronger meds.
For proven hair regrowth, talk to a dermatologist about FDA approved minoxidil and finasteride before spending money on supplements.
When is the Best Time to Start Treatment?
Since male pattern baldness is progressive, beginning treatment as soon as you notice thinning or recession rather than further down the line provides much better results. Medications like minoxidil and finasteride are more effective at thickening hair you still have as opposed to reviving follicles that have already died off and won’t regrow.
Aim to begin 6-12 months BEFORE balding becomes a major cosmetic issue, while substantial hair remains in place to work with. Be proactive!
Commit to daily use for at least 6-9 months before assessing results since hair growth is a slow process. Continued long term therapy then maintains benefits.
Summing it Up – Key Takeaways
Androgenetic alopecia causes 50% of men to experience hereditary hair loss to some degree
Genetics, DHT, aging and hair cycles contribute
Start treatment ASAP once thinning becomes noticeable
Daily minoxidil and oral finasteride provide best medical regrowth ability and stabilization
Hair transplants can restore hairlines for fuller frame/density
Regrow 30-40% more hair using meds plus get transplants
Commit to daily treatment and regular follow up assessments
Schedule an office visit if you believe you’re experiencing early genetic hair loss. An experienced dermatologist will diagnose what’s causing the problem and help devise an appropriate treatment regimen for regaining hair. Consistent therapy, once begun, provides men the best ability to stabilize hair loss and regrow more volume long term.
