Overview
Alopecia refers to hair loss that can occur on the scalp or other parts of the body. It can affect both men and women and may occur suddenly or gradually. Alopecia can be caused by various factors and manifests in different forms, impacting individuals physically and emotionally.
Signs and Symptoms
Common signs and symptoms of alopecia include:
- Hair Thinning: Gradual thinning of hair on the scalp.
- Patchy Hair Loss: Small, coin-sized patches of hair loss on the scalp or other body areas.
- Complete Baldness: Loss of all hair on the scalp or body (alopecia totalis or universalis).
- Scalp Itching or Irritation: Sometimes accompanies hair loss.
- Nail Changes: Pitting or ridges in the fingernails.
Types
- Androgenetic Alopecia (Male Pattern Baldness/Female Pattern Baldness): Common form of hair loss due to genetic and hormonal factors.
- Alopecia Areata: Autoimmune disorder causing patchy hair loss on the scalp and sometimes body.
- Alopecia Totalis: Complete loss of hair on the scalp.
- Alopecia Universalis: Loss of hair on the entire body.
- Telogen Effluvium: Temporary hair shedding due to stress, illness, or hormonal changes.
- Traction Alopecia: Hair loss due to repetitive pulling or tension on the hair.
- Lichen Planopilaris: Rare inflammatory condition that causes hair loss and scalp scarring.
- Scarring Alopecia: Hair loss caused by the destruction of your hair follicles.
Diagnosis
Diagnosing alopecia typically involves:
- Medical History: Discussion of symptoms and family history of hair loss.
- Physical Examination: Inspection of the scalp and affected areas.
- Pull Test: Gently pulling on hair to see how many hairs come out.
- Scalp Biopsy: Removal of a small piece of scalp skin for laboratory analysis.
- Blood Tests: To check for underlying medical conditions or nutritional deficiencies.
Treatment
Treatment for alopecia may include:
Medical Treatments
- Topical Treatments: Minoxidil (Rogaine) applied to the scalp to stimulate hair growth.
- Oral Medications: Finasteride (Propecia) for male pattern baldness, and corticosteroids for alopecia areata.
- Injections: Corticosteroid injections directly into the scalp for alopecia areata.
- Immunotherapy: Stimulating hair regrowth by irritating the skin with a chemical (diphencyprone) in cases of alopecia areata.
- Light Therapy: Exposure of the scalp to ultraviolet light (phototherapy) to stimulate hair regrowth.
- Platelet-Rich Plasma (PRP) Therapy: Injecting concentrated platelets from the patient's blood into the scalp to promote hair growth.
Non-Pharmacological Treatments
- Wigs or Hairpieces: For individuals with extensive hair loss.
- Camouflage Techniques: Using hair fibers or scalp micropigmentation to conceal hair loss.
Surgical Treatments
Hair transplant surgery: Transplanting hair follicles from areas of dense hair growth to balding or thinning areas of the scalp.
