Hirsutism vs normal hair: how to tell the difference
Most women have visible hair on the face and body, and most of it is entirely normal. Hirsutism is something specific: coarse, pigmented hair growing in a pattern typical of male hair distribution. This page explains where the line sits, how clinicians score it, and which signs mean it is worth getting tested.
Quick answer
Normal female hair is mostly fine, soft vellus hair, plus terminal hair on the arms and legs. Hirsutism means coarse, dark terminal hair in androgen-dependent areas — upper lip, chin, jawline, chest, upper abdomen, back, inner thighs. Distribution and hair type matter more than quantity.
Two kinds of hair
Vellus hair is short, fine, soft, and usually unpigmented — the "peach fuzz" covering nearly the whole body. Terminal hair is longer, thicker, and pigmented, like scalp hair, eyebrows, and underarm hair.
Androgens can convert vellus follicles into terminal ones in specific, androgen-sensitive areas. That conversion is what hirsutism describes. It is not the same as peach fuzz becoming more noticeable, and it is not the same as hypertrichosis, which is excess hair anywhere on the body regardless of pattern or hormones.
Where the hair is matters more than how much
| Usually normal | Suggestive of hirsutism |
|---|---|
| Fine fuzz on cheeks and jaw | Coarse, dark hairs on the chin and jawline |
| A few darker hairs on the upper lip | A defined dark shadow across the upper lip |
| Hair on forearms and lower legs | Hair on the chest, between the breasts, upper back |
| A fine line below the navel | Coarse hair from the navel up toward the sternum |
| A few hairs around the nipples | Dense coarse hair across the chest or lower back |

The Ferriman-Gallwey score
Clinicians grade terminal hair from 0 to 4 in nine androgen-sensitive areas — upper lip, chin, chest, upper back, lower back, upper abdomen, lower abdomen, upper arms, and thighs — then add the scores. The threshold for hirsutism varies by ethnicity because hair density differs substantially between populations; the Endocrine Society guideline notes that a single universal cut-off is not appropriate.
The score has real limits. It does not account for hair you have already removed, and it under-recognises women with distressing hair confined to a single area — sometimes called idiopathic or focal hirsutism.
When to get checked
- Rapid onset or fast worsening over weeks to months.
- Hirsutism plus irregular or absent periods.
- Signs of virilisation: deepening voice, temple hair loss, increased muscle bulk.
- New onset after menopause.
- Associated severe acne, unexplained weight change, or difficulty conceiving.
Typical first-line tests include total and free testosterone, DHEA-S, 17-hydroxyprogesterone, prolactin, and thyroid function. Read the full hirsutism guide before your appointment.
Managing it either way
Whether or not you meet a diagnostic threshold, the toolkit is the same: a removal method you tolerate, a reduction approach that changes regrowth, and sun protection to prevent the darkening removal can leave behind. Medical options are compared in medical vs natural treatment. On the topical side, Mohammed's 2014 study found Cyperus rotundus oil reduced hair growth in idiopathic facial hirsutism, and a 2022 trial reported reduced post-inflammatory pigmentation after hair removal — see how the oil works.
Frequently asked questions
How do you pronounce hirsutism?
It is commonly pronounced HUR-soot-ism (or HUR-syoo-tizm in British English). The word comes from the Latin hirsutus, meaning shaggy or bristly.
What is the ICD-10 code for hirsutism?
Hirsutism is coded as L68.0 in ICD-10, under hypertrichosis. Clinicians may also code the underlying cause, such as polycystic ovarian syndrome, separately.
Is hirsutism the same as having a lot of body hair?
No. Hirsutism specifically means coarse, pigmented hair in androgen-dependent areas following a male-pattern distribution. Generalised excess hair without that pattern is called hypertrichosis and has different causes.
Can you have hirsutism with normal hormone levels?
Yes. This is called idiopathic hirsutism and is thought to reflect increased follicle sensitivity to normal androgen levels rather than excess circulating hormone.
Is chin hair in women normal?
A few stray hairs are extremely common and normal, particularly with age. Dense, coarse chin and jaw hair that returns quickly is more consistent with hirsutism and worth discussing with a clinician.
Does hirsutism go away on its own?
Not usually. Where it is driven by a treatable cause such as PCOS, treating that cause slows new growth, but existing terminal hairs remain and still need removal or reduction.
