What causes hair loss in men?
The overwhelming majority of male hair loss is androgenetic alopecia, or male pattern baldness. It's driven by genetics and sensitivity to dihydrotestosterone (DHT), a hormone that gradually shrinks susceptible follicles at the temples, front and crown. Over time those follicles produce thinner, shorter hairs until they stop producing visible hair altogether. Follicles at the back and sides are usually resistant to DHT, which is why transplants use them.
Not all male hair loss is pattern baldness, though. Other causes include:
- Telogen effluvium - diffuse shedding after illness, surgery, crash dieting or major stress
- Alopecia areata - an autoimmune condition causing round, patchy bald spots
- Thyroid disorders and nutritional deficiencies, such as low iron
- Medications, including some used for blood pressure, mood or cancer treatment
- Scalp conditions such as severe dermatitis or fungal infection
- Scarring alopecias, which destroy follicles and need specialist treatment
- Traction alopecia from tight braids, man buns or helmets worn the same way daily
Because these need different treatment, a diagnosis should always come before a restoration plan. See our signs and symptoms hub.
When is male hair loss not just pattern baldness?
Pattern baldness develops slowly and symmetrically, over years. See a doctor promptly, rather than starting a restoration plan, if you notice:
- Hair coming out in clumps or large amounts over a few weeks
- Round, smooth patches on the scalp or in the beard
- Redness, pain, burning, pustules or scaling on the scalp
- Loss of eyebrows, eyelashes or body hair as well
- Hair loss alongside fatigue, weight change, feeling cold or other new symptoms
- Thinning that began soon after starting a new medication
These signs can point to conditions that respond well to medical treatment - and some scarring conditions cause permanent loss if left alone. A dermatologist can usually tell the difference with an examination and, if needed, blood tests or a scalp biopsy.
How is male pattern baldness measured?
Doctors commonly use the Norwood scale, which runs from stage 1 (no significant recession) to stage 7 (only a horseshoe band of hair remains at the sides and back). Stages 2–3 involve temple recession, stages 3–4 bring crown thinning, and stages 5–7 see the front and crown merge into a larger bald area.
Your stage, along with your age and family history, helps predict where your hair loss is heading and how many grafts a transplant might need. It isn't a perfect predictor, which is why progress photos over time are so valuable.
What are all the male hair restoration options?
| Option | Category | Best for | Main drawback |
|---|---|---|---|
| Finasteride | Medical | Slowing or halting pattern loss | Prescription; possible side effects; ongoing |
| Minoxidil | Medical | Regrowing thinning hair, especially the crown | Must be continued; early shedding possible |
| PRP | In-office | Adding support to medication | Mixed evidence; repeat sessions |
| Low-level laser | Device | Mild to moderate thinning | Modest effect; consistent use needed |
| FUE transplant | Surgical | Established loss; short hairstyles | Higher cost per graft; limited donor supply |
| FUT transplant | Surgical | Large graft needs; longer hairstyles | Linear donor scar |
| Scalp micropigmentation | Cosmetic | Shaved-head look or adding density illusion | Doesn't grow hair; fades and needs touch-ups |
| Hair system | Cosmetic | Instant full coverage at any stage | Ongoing maintenance and replacement costs |
Many men combine options - for example, finasteride and minoxidil to hold existing hair, a transplant for the front, and SMP to soften a thin crown.
How do you choose between medical, surgical and cosmetic routes?
Think about three questions:
- Is the hair still there? If follicles are thinning but present, medical treatment can help. If an area is smooth and bald, only a transplant (or a cosmetic solution) will change it.
- Do you have enough donor hair? Transplants redistribute a finite supply. Men with advanced loss and a weak donor area may not be able to achieve full coverage.
- What trade-offs can you live with? Daily medication, surgery and recovery, or ongoing cosmetic maintenance - each has costs beyond money.
Our types and options hub explains each route in more detail.
Who is a good candidate for a male hair transplant?
- Confirmed male pattern hair loss, ideally with a fairly predictable pattern
- A dense, healthy donor area at the back and sides
- Realistic expectations about density and future loss
- Willingness to use medication to protect native hair, or understanding of the risks if not
- Good general health and no uncontrolled medical conditions
Men with very rapid loss, a diffuse unstable pattern that includes the donor area, or certain scarring conditions may be advised against surgery.
What does male hair restoration cost?
Generic minoxidil and finasteride are usually the cheapest long-term options. PRP runs roughly $500–$1,500 per session. US hair transplants typically cost $4,000–$15,000 in total, or $3–$8 per graft - small procedures of 500–1,500 grafts around $4,000–$8,000, medium procedures of 1,500–2,500 grafts around $8,000–$12,000, and large sessions $12,000–$15,000 or more. Insurance almost never covers cosmetic hair restoration, but financing is widely available. See men's hair transplant cost for more detail.
What results can men realistically expect?
Medication tends to stabilise loss and bring modest regrowth, judged after 6–12 months. A transplant usually shows visible change around 6 months and a final result around 12 months, up to 18 for the crown. Transplanted hair is generally permanent, but a transplant can't recreate the density of a full teenage head of hair across a large bald area - the aim is natural-looking coverage that frames the face.

What should you do next?
Start with a proper diagnosis, then match the treatment to your stage and goals. If you're considering surgery, get two or three consultations to compare. You can request a free quote from vetted US hair restoration providers.

Frequently asked
There's no permanent cure, but it can be managed very effectively. Medication can slow or halt progression, and transplants permanently move DHT-resistant hair to bald areas. Most men combine approaches.
Genes from both parents contribute. One important gene sits on the X chromosome, inherited from your mother, but baldness on your father's side also raises your risk.
Normal hat wearing doesn't cause pattern baldness. Very tight headwear worn constantly in the same position could contribute to traction, but that's uncommon. Keep hats clean and not overly tight.
Stress can trigger temporary shedding (telogen effluvium) and may make existing thinning more noticeable, but it doesn't cause genetic pattern baldness. Stress-related shedding usually recovers within several months.
Indirectly. Testosterone converts to DHT, which shrinks genetically sensitive follicles. Men with normal testosterone levels can still lose hair if their follicles are sensitive to DHT.
SMP is a cosmetic tattooing technique that places tiny pigment dots on the scalp to mimic hair stubble or add the look of density. It doesn't grow hair and typically needs periodic touch-ups.
Supplements help only if you have a genuine deficiency, such as low iron or vitamin D. They don't stop genetic pattern baldness. Ask your doctor to test levels before taking high doses.
