Is it really hair loss?

Shedding 50–100 hairs a day is normal. Concerns start when:

  • You see more scalp in certain areas
  • Your part has widened
  • Ponytail is noticeably thinner
  • You shed 150+ hairs daily for 2+ months

Six common causes in women

1. Telogen effluvium (TE)

Triggered by a stressor: illness, surgery, major weight loss, childbirth, severe emotional stress. Hair sheds 2–4 months after the event.

Good news: Usually reversible in 6–12 months. The new growth is normal.

What helps: Nutrition (iron, protein, vitamin D), stress management, gentle hair care, time.

2. Androgenetic alopecia (female pattern hair loss)

Genetic hair thinning, typically at crown and part line. Often accelerates at menopause.

What helps:

  • Minoxidil 2% or 5% (topical, FDA-approved for women)
  • Low-level laser therapy
  • PRP (platelet-rich plasma) injections
  • Finasteride or spironolactone (prescription only, for some cases)

3. Postpartum hair loss

A form of TE. Most women shed 3–6 months after giving birth. Normal baseline usually returns by month 12.

4. Nutrient deficiency

  • Iron (ferritin) — #1 deficiency in women causing hair loss
  • Vitamin D — low in many women
  • B12 — common in vegans
  • Zinc — linked to shedding
  • Protein — essential for hair building

Get blood tests before supplementing. Over-supplementing can cause loss too.

5. Thyroid

Both hyperthyroidism and hypothyroidism cause diffuse thinning. Often reversible once thyroid is balanced.

6. Traction alopecia

From tight hairstyles, extensions, or braids. Localized thinning where tension is greatest. Can become permanent if not addressed.

What helps: Loosen styles immediately. If caught early, hair regrows.

What to do first

  1. See a doctor — get blood tests: CBC, ferritin, vitamin D, B12, thyroid panel (TSH, T3, T4).
  2. Take photos of your part and hairline monthly to track change objectively.
  3. Review triggers — was there an illness, stressor, or big life event 2–4 months ago?
  4. Check medications — many cause hair loss: antidepressants, blood thinners, birth control changes, beta blockers.

What helps most people

  • Eat enough protein (0.8–1g per kg body weight minimum)
  • Iron-rich foods (red meat, lentils, spinach) + vitamin C to absorb
  • Manage stress — chronic cortisol disrupts hair cycle
  • Sleep 7–9 hours
  • Gentle scalp massage daily — increases blood flow, measurably small but non-zero benefit

What doesn't really work

  • Biotin supplements — unless you're actually deficient (rare)
  • "Hair growth" shampoos — they can't grow hair from outside
  • Caffeine shampoos — mild effect, far less than minoxidil
  • Most "natural" oil treatments

Castor oil may slightly help scalp circulation but doesn't regrow lost hair.

When to see a specialist

  • Shedding persists 6+ months
  • Visible bald patches
  • Hair loss with other symptoms (fatigue, weight changes, irregular periods)
  • Family history of hair loss + you're under 40

A dermatologist or trichologist can diagnose specific conditions and prescribe effective treatments.

Hair care during hair loss

  • Avoid tight styles
  • Gentle shampoo
  • Skip bleach and heat
  • Detangle only when wet with conditioner
  • Trim ends to make thinning less visible

The Mutaly quiz identifies hair loss signals and adjusts the routine to minimize further stress on fragile hair.
