Hair loss in women

Area of Science:

• Dermatology
• Endocrinology
• Trichology

Background:

• Female pattern hair loss (FPHL) is a prevalent condition affecting women, often linked to androgen levels.
• Classifications like Ludwig's and Olsen's categorize FPHL based on pattern, severity, and onset, with or without androgen excess.
• Female androgenetic alopecia (FAGA) specifically involves increased androgens and presents with diffuse hair loss in parietal or frontovertical areas, preserving the frontal hairline.

Purpose of the Study:

• To review the classification, diagnosis, and treatment of female pattern hair loss (FPHL).
• To outline diagnostic methods including clinical assessment, trichoscopy, and hormonal testing.
• To discuss therapeutic strategies for FPHL, addressing both androgenetic and non-androgenetic forms.

Main Methods:

• Review of existing literature on FPHL classification and management.
• Description of diagnostic tools such as clinical history, physical examination, wash tests, dermoscopy, trichoscopy, and laboratory analyses (including androgen levels).
• Summary of treatment options including topical minoxidil, systemic antiandrogens, hormonal therapies, and supportive measures.

Main Results:

• FPHL diagnosis relies on a combination of clinical findings and specific tests, particularly androgen level determination.
• Topical minoxidil is a primary treatment for FPHL.
• Systemic antiandrogenic therapy is crucial for FPHL associated with elevated androgen levels, with various agents and hormonal suppressions detailed for different hyperandrogenic conditions (adrenal, ovarian, pituitary).
• Other treatments include GnRH agonists, metformin for PCOS with insulin resistance, bromocriptine/cabergoline for hyperprolactinemia, and finasteride/dutasteride for postmenopausal alopecia.
• Dermatocosmetic solutions and weight loss in hyperandrogenic women are also noted as beneficial.

Conclusions:

• FPHL management requires accurate diagnosis through comprehensive evaluation and targeted testing.
• Treatment strategies are tailored to the underlying cause, with a focus on topical minoxidil and systemic antiandrogens for hyperandrogenic FPHL.
• A multi-faceted approach, including hormonal therapy, supportive treatments, and lifestyle modifications, is key to effectively managing FPHL.
