  4. 4. Alopecia Areata (AA): • Alopecia areata is an autoimmune condition which causes patchy hair loss. It can result in a single bald patch or extensive patchy hair loss.

  10. 10. • Alopecia Barbae • Alopecia barbae is alopecia areata that is localised to the beard area. It can be a single bald patch or more extensive hair loss across the whole of the beard area.
  11. 11. Alopecia Barbae
  12. 12. Androgenetic Alopecia (AGA) • Also known as male pattern baldness or female pattern baldness. • It is a thinning of the hair to an almost transparent state, in both men or women. • It is hereditary • In both men and women, it's linked to having an excess of male hormones (androgens) around the hair follicles, which can block hair growth. • Women are more likely to develop androgenic alopecia after menopause, when they have fewer female hormones. • Most cases of hair loss are due to androgenic alopecia.
  13. 13. male pattern baldness
  14. 14. female pattern baldness
  15. 15. Scarring Alopecias (Cicatricial Alopecias): • Scarring alopecias refers to a group of rare disorders which cause permanent hair loss. • Caused by any inflammatory processes which causes permanent damage to hair follicles.(burns, bacterial infections, autoimmune diseases )
  16. 16. Scarring Alopecias
  17. 17. Causes of alopecia: • Exposure to allergens, irritants, toxins, burns, injuries, and infections. • Certain medications (especially anabolic steroids like testosterone) • Chronic kidney failure • Radiation and chemotherapy . • Malnutrition
  18. 18. Treatment • Although hair loss rarely needs to be treated, many people seek treatment for cosmetic reasons. • There is no cure for alopecia and no universally proven therapy to induce hair re- growth.
  19. 19. • Many cases of hair loss are temporary, for example, due to chemotherapy, or they're a natural part of ageing and don't need treatment. • If hair loss is caused by an infection or another condition , treating the underlying problem may help prevent further hair loss.
  20. 20. Finasteride: • It acts by preventing the hormone testosterone being converted to the hormone dihydrotestosterone (DHT). • DHT causes the hair follicles to shrink, so blocking its production allows the hair follicles to regain their normal size. • The balding process usually resumes within six to 12 months if treatment is stopped
  21. 21. • Minoxidil: • Minoxidil is available as a lotion you rub on your scalp every day • It's not clear how minoxidil works, but evidence suggests it can cause hair regrowth in some men. • Minoxidil is currently the only medicine available to treat female-pattern baldness.
  22. 22. Corticosteroid injections: • Acts by suppressing the immune system. • This is useful in alopecia Areata because the condition is thought to be caused by the immune system damaging the hair follicles.
  23. 23. Retin A / Tretinoin: • Retin-A was originally used for the treatment of acne and other skin problems. • However studies have shown that Retin-A, when used alone in the form of a gel, which is rubbed onto the area of hair loss, or in combination with topical Minoxidil can result in moderate to good hair growth in individuals with Alopecia.
  24. 24. • Immunosuppressive drugs • Ultraviolet light treatment • Wigs -Synthetic wigs- made of acrylic -Real hair wigs • Hair transplantation
