What Are the Main Causes of Hair Loss in Men?
Male hair loss is a prevalent problem for men in America. Although hair loss occurs normally due to shedding every day, hair loss, receding hairline, or bald spots can be caused by a serious health problem. There are several reasons why men lose their hair, including genetics, age, nutrition, diseases, stress, and medications.
The main reason behind hair loss is important to know as various treatment methods are needed for different forms of hair loss. Male pattern hair loss can be treated with medications such as finasteride 1mg that will prevent additional hair loss and encourage hair growth.
1. Male Pattern Hair Loss
The first reason why men lose hair is male pattern hair loss, which is scientifically referred to as androgenetic alopecia. Genetics inherited from mother's and/or father's side of the family cause hair follicles' sensitivity to androgens – hormones.
With time, the follicles shrink and generate thinner and shorter hair. Men can begin to see a receding hairline, a thinning at the crown area, or thinning on the top of the scalp.
Finasteride 1mg tablets could be prescribed for male pattern hair loss in men. Finasteride lowers the production of dihydrotestosterone, which causes miniaturization of sensitive hair follicles.
2. Aging
As people age, hair grows differently. Follicles become inactive, and the hairs themselves become finer. As a consequence, many men face hair thinning when aging.
Moreover, hair becomes easier to recognize in older age. The American Academy of Dermatology says that hair stops growing fast when people grow old.
3. Stress and Illnesses
Severe emotional or physical stress can cause excess hair loss. It may happen after an acute illness, a fever, surgery, or any other strong physical stress factor.
Such a condition may take time before it manifests. Hair fall may be noticed even months later following the stressful experience. Generally, hair fall may subside on its own once the reason is gone.
If one experiences sudden and severe hair loss, then the problem should not be diagnosed as male-pattern hair loss until seen by a health care professional.
4. Nutritional Problems
A nutritional deficiency may be associated with hair loss. Insufficiency in iron, protein, zinc, and biotin may be identified among the causes of hair loss by the AAD.
But taking more than required nutrients as a supplement is not beneficial. Taking excessive nutrients may aggravate hair loss. It would be best to consult a health care professional on such an issue.
5. Health Conditions
Some health conditions are capable of disrupting the natural hair growth process. For instance, hair thinning or hair fall may be caused by thyroid problems.
There are autoimmune diseases like alopecia areata that may lead to hair fall and loss. Certain infections or inflammation of the scalp may affect hair growth.
These medical conditions require totally different treatment measures.
6. Drugs and Medical Interventions
Certain prescription drugs can induce hair loss as a side effect. Other treatments, including chemo and radiation therapy if conducted in the neck or head region, can also lead to hair loss.
It is important to talk to the prescribing doctor regarding a medication that causes hair loss and not just discontinue its use.
7. Damage to Hair and Scalp
Hair damage through chemical treatments and exposure to extreme heat, along with damaging hair treatments, can make the hair vulnerable to breakage and even loss. Hairstyles which exert tension on the hair continuously can also lead to traction alopecia.
Careful hair care and protection from damage can be helpful.
Comparison Between Finasteride 1mg and Finasteride 5 mg for Hair Loss
Finasteride 1mg is the dosage usually used for treating male pattern baldness. The drug helps lower DHT levels and thereby slows down follicle miniaturization.
However, Finasteride 5 mg is a stronger formulation of the drug that is mainly used for benign prostatic hyperplasia (BPH) and is not considered a recommended dose for treating male pattern hair loss. One should not switch to the higher strength dose of finasteride, i.e., 5 mg, just assuming that the higher dose will give better results.
Finasteride is a prescription medicine and should be prescribed only after a consultation with a healthcare provider because there are some possible adverse effects associated with it such as sexual side effects and others that should be discussed beforehand.
In case of genetic hair loss, early treatment can be important because it is easier to preserve existing follicles rather than regrow hair when follicle miniaturization has already been established to a large extent.
When should men see a doctor about hair loss?
Consultation is required if hair loss:
- Onset is sudden or rapid
- Consists of well-defined bald patches
- Is associated with pain, redness, scaling, or inflammation of the scalp
- Causes excessive shedding following illness
- Is combined with other inexplicable symptoms
- Doesn’t improve with hair-care changes
The dermatologist will be able to check the patient’s scalp and hair pattern, as well as evaluate medications and the medical history, and decide whether further testing is required.
