    TLDR Female hair loss can be diagnosed using specific trichoscopy criteria.
    This study analyzed the differences in hair thickness and percentage of thin hairs between healthy controls, androgenic alopecia, and chronic telogen effluvium in 150 women. The study established diagnostic criteria for female androgenic alopecia based on trichoscopy criteria, including major criteria of increased number of yellow dots, thin hairs, and decreased average hair thickness in the frontal area, and minor criteria of increased frontal area to occiput ratio of single-hair units, vellus hairs, and follicles with perifollicular discoloration. The study concluded that the diagnosis of female androgenetic alopecia may be established based solely on trichoscopy criteria.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      The user experienced hair loss despite using Fin and Min for 12 years and switched to Dutasteride, RU58841, and Keto scalp serum, but shedding and itch persist. They are considering increasing Dutasteride to 2.5mg and questioning the necessity of a scalp biopsy, with mixed opinions on its usefulness.

      A user is experiencing rapid hair loss and has been diagnosed with telogen effluvium by multiple dermatologists, but doubts the diagnosis due to the severity and speed of the hair loss. They are considering various treatments like spironolactone, estradiol, and possibly finasteride, while also exploring the possibility of hormonal imbalances or autoimmune issues.

      community My Theory Of Androgenic Alopecia

      in Research/Science  19 upvotes 4 months ago
      Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.
