1. Androgenetic Alopecia
Overview:
Androgenetic alopecia, also known as male or female pattern baldness, is the most common form of hair loss in both men and women.
Causes:
- Genetics: A family history of hair loss is a significant factor.
- Hormones: Dihydrotestosterone (DHT), a derivative of testosterone, plays a crucial role in hair follicle miniaturization.
Symptoms:
- In men, hair typically thins at the crown and along the hairline.
- In women, hair often becomes thinner along the part line or at the crown.
Treatment Options:
- Minoxidil: An over-the-counter topical solution that promotes hair growth.
- Finasteride: An oral medication that blocks DHT production.
- Hair Transplant Surgery: A surgical option for those with significant hair loss.
2. Alopecia Areata
Overview:
Alopecia areata is an autoimmune disease characterized by sudden, patchy hair loss.
Causes:
The immune system mistakenly attacks hair follicles, though the exact cause is not fully understood. Genetic and environmental factors may contribute.
Symptoms:
- Round, smooth patches of hair loss on the scalp or other areas of the body.
- In some cases, it can progress to totalis (loss of all scalp hair) or universalis (loss of all body hair).
Treatment Options:
- Corticosteroid Injections: Reduce inflammation and promote regrowth.
- Topical Immunotherapy: Induces an allergic reaction to stimulate hair growth.
3. Telogen Effluvium
Overview:
Telogen effluvium is a temporary form of hair loss often triggered by stress, hormonal changes, or medical conditions.
Causes:
- Physical or emotional stress, major illness, surgery, or significant weight loss.
Symptoms:
- Diffuse thinning of hair rather than patchy loss.
- Increased hair shedding, particularly noticeable during washing or brushing.
Treatment Options:
- Stress Management: Techniques such as meditation, yoga, or counseling.
- Nutritional Support: Ensuring a balanced diet rich in essential nutrients.
4. Traction Alopecia
Overview:
Traction alopecia occurs due to prolonged tension on the hair follicles from certain hairstyles.
Causes:
- Tight hairstyles such as ponytails, braids, and extensions can lead to hair damage.
Symptoms:
- Thinning or balding along the hairline or areas where the hair is pulled tightly.
Treatment Options:
- Hairstyle Adjustment: Switching to looser styles can prevent further damage.
- Minoxidil: May help stimulate regrowth in affected areas.
5. Scarring Alopecia (Cicatricial Alopecia)
Overview:
Scarring alopecia encompasses a group of conditions that result in permanent hair loss due to follicular scarring.
Causes:
- Conditions such as lupus, lichen planopilaris, and folliculitis can damage hair follicles.
Symptoms:
- Hair loss accompanied by redness, inflammation, or scaling on the scalp.
Treatment Options:
- Anti-inflammatory Medications: Corticosteroids or other drugs to reduce inflammation.
- Hair Transplantation: An option if the scarring is stable and well-managed.
6. Hormonal Imbalance-Related Hair Loss
Overview:
Hormonal changes can lead to hair loss, particularly in women.
Causes:
- Conditions such as polycystic ovary syndrome (PCOS), menopause, or thyroid disorders can disrupt hair growth cycles.
Symptoms:
- Thinning hair, particularly noticeable around the crown or part.
Treatment Options:
- Hormonal Treatments: Addressing the underlying hormonal imbalance may help restore hair growth.
- Nutritional Support: A balanced diet can assist in managing symptoms.
