There are several potential causes of baldness, also known as hair loss. Some reasons are hormonal and genetic in nature, while others are associated with one’s way of life, underlying diseases, or environmental influences.
Be aware that different people will experience hair loss due to different causes and that many factors may work simultaneously in some cases.
If you are experiencing severe hair loss, it is recommended that you seek guidance from a healthcare professional or a dermatologist in order to identify the root cause and consider suitable treatment alternatives.
Here are some common, non-genetic causes of hair loss:
1. Age: Hair loss is a natural part of ageing for many people. Hormonal changes and genetic factors can have an impact on both male-pattern baldness (androgenetic alopecia) and female-pattern baldness.
2. Physical and Emotional Stress:
- Telogen Effluvium: Severe physical or emotional stress, illness, or major life changes can lead to a temporary condition called telogen effluvium, causing increased hair shedding.
3. Smoking: Smoking has been linked to hair loss, likely due to reduced blood flow to the hair follicles.
4. Hormonal Changes: Fluctuations in hormones, such as those that occur during pregnancy, childbirth, menopause, or thyroid disorders, can lead to hair loss.
5. Nutritional Deficiencies:
- Iron Deficiency: Anaemia due to iron deficiency can contribute to hair loss.
- Vitamin Deficiencies: Inadequate intake of certain vitamins and minerals, such as zinc, vitamin D, and vitamin B12, can impact hair health.
- Excessive Vitamin A: Consuming too much vitamin A, either through diet or supplements, can contribute to hair loss.
6. Environmental Factors:
- Exposure to Harsh Chemicals: Overexposure to harsh chemicals in hair dyes, relaxers, or other styling products can damage the hair and contribute to hair loss.
- Extreme Heat or Cold: Extreme environmental conditions can stress the hair and contribute to breakage.
7. Weight Loss or Crash Diets: Rapid weight loss or extreme dieting can result in nutrient deficiencies, leading to hair loss.
8. Alcohol abuse: Consuming too much alcohol can lead to dehydration, which can negatively impact the overall health of your hair. Excessive alcohol consumption can result in inadequate nutrient intake, which can worsen the condition of hair loss.
9. Medical Conditions:
- Autoimmune Diseases: Conditions like alopecia areata involve the immune system attacking hair follicles, leading to hair loss.
- Medical Conditions such as lupus, diabetes, and certain fungal infections can contribute to hair loss.
- Thyroid Disorders: Both hypothyroidism and hyperthyroidism can cause hair thinning or loss.
- Scalp Infections: Fungal infections or other scalp conditions can damage hair follicles and result in hair loss.
10. Alopecia Areata: This is an autoimmune condition where the immune system attacks hair follicles, leading to hair loss in patches.
11. Medical Treatments:
- Chemotherapy: Cancer treatments, particularly certain chemotherapy drugs, can lead to hair loss as a side effect.
- Radiation Therapy: Hair loss may occur in areas exposed to radiation during cancer treatment.
- Certain Drugs: Some medications, including those used for cancer, arthritis, depression, heart problems, gout, and high blood pressure, can cause hair loss as a side effect.
12. Tight Hairstyles and Hair Treatments: Excessive pulling or tension on the hair (traction alopecia) due to tight hairstyles, braids, or hair treatments can cause hair loss.
