Hair Loss Causes In Men

  • Male pattern baldness, also known as androgenetic alopecia (a genetic condition)
  • Heredity/family history of hair loss
  • Extreme stress
  • Side effects from medications
  • Medical illnesses (thyroid conditions or systemic diseases such as lupus)
  • Traction hair loss, also known as traction alopecia (from excessive pulling and braiding)
  • Burn or major surgery scars
  • Nutritional deficiencies (poor diet, iron deficiency, etc.)
  • Hormonal imbalances (pregnancy, menopause, birth control pills)

The Norwood Hair Scale

The most widely accepted standard for categorizing the different stages of Male Pattern Baldness is known as the Norwood Hair Scale. The scale goes from Type 1 to Type 7 hair loss, Type 1 being the lowest. For most, thinning begins young yet does not become very apparent until their late 20s, early 30s. Maximum pattern is usually attained by the time one is 50 years old, with ongoing thinning occurring throughout the remainder of one’s life.

The seven stages of hair loss include:

  • Stage 1: No significant hair loss or recession of the hairline.
  • Stage 2: There is a slight recession of the hairline around the temples. This is also known as an adult or mature hairline.
  • Stage 3: The first signs of clinically significant balding appear. The hairline becomes deeply recessed at both temples, resembling an M, U, or V shape. The recessed spots are completely bare or sparsely covered in hair.
  • Stage 3 Vertex: The hairline stays at stage 2, but there is significant hair loss on the top of the scalp (the vertex).
  • Stage 4: The hairline recession is more severe than in stage 2, and there is sparse hair or no hair on the vertex. The two areas of hair loss are separated by a band of hair that connects to the hair remaining on the sides of the scalp.
  • Stage 5: The two areas of hair loss are larger than in stage 4. They are still separated, but the band of hair between them is narrower and sparser.
  • Stage 6: The balding areas at the temples join with the balding area at the vertex. The band of hair across the top of the head is gone or sparse.
  • Stage 7: The most severe stage of hair loss, only a band of hair going around the sides of the head remains. This hair is usually not dense and may be fine.
  • Norwood Class A: The class A variation of the Norwood scale is a slightly different and less common progression of hair loss. The main differences are that the hairline recedes back uniformly, without leaving an island of hair in the middle, and there is no bald area at the vertex. Instead, the hairline progresses directly from front to back.
