Back Hair

The majority of men (70%) will have some hair growth on the back.  Hair grows in six distinct zones on the back – three on the upper back and three on the lower back.[i]

UPPER BACK

Over half of all men (53%) have upper back hair.  Hair on the upper back grows in three distinct areas.  The first is the top of the shoulders (left), the second is a V-shaped pattern at the base of the neck (middle), and the third is hair on the shoulder blades (right).

Hair growth on the upper back ranges from no hair growth at all to hair covering the entire upper back.  It also occurs in one or more combinations of the zones shown above.  The prevalence of these different hair growth patterns in various ethnic groups is shown in the chart below:

LOWER BACK

Growing hair on the lower back is more common than having hair on the upper back.  In fact, 61% of men overall have hair on the lower back.  Hair on the lower back grows in three distinct areas.  The first is in the small of the back (left), the second is the upper lats (middle), and the third is hair on the lower lats (right).
