Hair loss in women can be caused by a variety of factors, ranging from genetic predisposition to lifestyle choices and underlying medical conditions. Here are some common causes:

女性脫髮可能由多種因素引起，從遺傳易感性到生活方式選擇和潛在的醫療條件。以下是一些常見原因：

1. Genetic Factors (Androgenetic Alopecia):
   遺傳因素（雄激素性脫髮）：

   • Female pattern hair loss, also known as androgenetic alopecia, is the most common type of hair loss in women. It is influenced by genetics and hormones, leading to thinning hair, particularly along the top and crown of the scalp.
     女性型脫髮，也稱為雄激素性脫髮，是女性最常見的脫髮類型。它受遺傳和激素的影響，導致頭髮稀疏，尤其是頭皮頂部和頭頂。

     Hair restoration techniques, such as PRP therapy (Platelet-Rich Plasma) or hair transplant surgery, may be viable for advanced cases.
     頭髮修復技術，例如 PRP 療法（富血小板血漿）或頭髮移植手術，可能適用於晚期病例。
