What should you know about DHT hair loss?

DHT is made from testosterone and can shorten the active growth phase of susceptible follicles. Over time, affected hairs may become finer and shorter. The pattern often involves a receding hairline, thinning at the crown, or widening over the central scalp, while the sides and back may remain fuller. This pattern is commonly called androgenetic alopecia; it can occur in men and women, with different distributions.

Hair loss can also follow illness, stress, nutritional problems, scalp inflammation, infection, autoimmune disease, or sustained pulling. DHT is therefore a possible mechanism, not a diagnosis based on shedding alone.

Arrange a dermatology assessment if thinning is persistent or changing. The clinician may examine the scalp, ask when shedding began, review medicines and family history, and distinguish broken hairs from reduced density. Take clear photographs in similar lighting so gradual change is easier to discuss.

Treatment depends on the pattern, age, health history, and pregnancy considerations. A clinician may discuss prescription options such as Finasteride Treatment, along with gentle hair care and management of another cause if one is found. Do not start hormone-affecting treatment without advice.

Seek prompt medical review for sudden or rapidly worsening loss, smooth bald patches, scalp pain, marked redness, swelling, pus, heavy scaling, or broken hairs with itching. New hair loss with changes such as irregular periods, increased facial hair, voice change, severe fatigue, or unexplained weight change also deserves assessment.

For broader context, see Hair Loss and compare patterns such as Male Pattern Hair Loss, Female Pattern Hair Loss, Alopecia Areata, Scalp Ringworm, Telogen Effluvium, or Traction Alopecia.

Could my pattern fit androgenetic alopecia, or do the scalp findings suggest another cause? Should any blood tests or scalp examination be considered? Which treatment benefits, side effects, monitoring needs, and pregnancy precautions apply to me? What change should prompt an earlier review?
