What is PMOS-related hair loss (PCOS)?
Polyendocrine Metabolic Ovarian Syndrome (PMOS), formerly known as Polycystic Ovary Syndrome (PCOS), is a complex endocrine condition. One of its key features is excess androgen activity, involving hormones such as testosterone.
At the scalp, this androgen activity can affect the hair follicles, causing them to gradually shrink and produce finer, shorter hairs. This is often a form of female pattern hair thinning associated with the hormonal imbalance linked to PMOS.
Most common signs of PMOS (PCOS) hair loss
“Christmas tree” pattern
A widening of the centre parting that spreads outward, resembling a Christmas tree shape.
Temporal recession
Thinning around the temples may occur alongside wider pattern hair thinning across the scalp.
Acne & hirsutism
You may simultaneously experience hair loss on the scalp and unwanted hair growth on the face or body.
Greasy scalp
Increased androgen activity may contribute to excess sebum production, causing oily roots and scalp discomfort.
Who PMOS (PCOS) hair loss affects
This affects women of reproductive age. It is often diagnosed in the late teens or 20s, making it particularly distressing for young women. It is a lifelong condition, but the hair loss symptoms can be managed.
Why early assessment of PMOS (PCOS) matters
PMOS hair loss is internal. Treating it requires a two-pronged approach: managing the internal hormonal environment and externally stimulating the scalp to protect the follicles from androgen attacks. Waiting too long can lead to permanent follicular miniaturisation.
Internal management
Managing the internal hormonal environment, often alongside your GP or endocrinologist.
Scalp support
Externally stimulating the scalp to build a routine that maximises retention and improves density.

As estrogen levels drop during perimenopause and menopause, hair can become finer, drier, and prone to falling out.
