Which Hormone Causes Hair Loss in Females? A Complete Guide
Which Hormone Causes Hair Loss in Females? A Complete Guide
Noticing your hair thinning gradually can feel confusing and sometimes, concerning. This guide explains which hormone causes hair loss in females, how hormonal shifts affect the hair cycle, and what consistent Ayurvedic care can do to support steady progress. Whether you are dealing with postpartum changes, thyroid imbalance, or stress, this is a calm, evidence-led starting point. You may have noticed it gradually. More strands on your comb. A parting that looks wider. A ponytail that feels thinner than before. The experience of hormonal hair loss in women does not arrive all at once. It builds slowly - until one day you stop and wonder: what is changing inside my body? More often than not, the answer is hormones. These tiny chemical signals control almost everything in the body, including how your hair grows. Understanding which hormone causes hair loss in females is the first step from worry to action.
01 HOW DO HORMONES AFFECT HAIR?
Hair grows in stages: a growth phase, a rest phase, and a shedding phase. Hormones decide how long each stage lasts.
When hormones go out of balance - because of age, health, or stress - more follicles move into the shedding phase at once. That is when female hair thinning reasons start to show.
Research on PubMed confirms that hormonal imbalances are one of the most common causes of hair loss in women.

02 WHICH HORMONE CAUSES HAIR LOSS IN FEMALES?
Several hormones can play a role. Here is a simple breakdown:
- DHT (Dihydrotestosterone)
DHT comes from testosterone. Women make small amounts of testosterone too. When DHT levels rise or when hair follicles are extra sensitive to it, the growth phase gets shorter. Follicles slowly shrink and produce thinner strands. This is called female pattern hair loss, and it is one of the most common female hair thinning reasons. - Oestrogen and Progesterone
These hormones are good for hair. High oestrogen (like during pregnancy) keeps hair in the growth phase longer, which is why many women have thicker hair while pregnant.
After childbirth, oestrogen drops fast. This causes a wave of shedding, called postpartum hair loss. It is one of the most talked-about forms of hormonal hair loss in women. The good news? It is usually temporary.
Menopause brings a similar drop, which is why thinning often increases in mid-life. - Thyroid Hormones
The thyroid controls your body's energy. When it is too slow (hypothyroidism) or too fast (hyperthyroidism), hair sheds across the whole scalp. According to the NHS, hair loss is often one of the first signs of a thyroid problem. - Cortisol — The Stress Hormone
When you are stressed for a long time, your body makes more cortisol. This pushes follicles into the resting phase too early. The result? More shedding, usually two to three months after the stressful event. Poor sleep and emotional strain add to this too. - Insulin (Linked to PCOS)
Polycystic ovary syndrome (PCOS) affects insulin in the body, which raises androgen levels. This speeds up follicle shrinkage, making PCOS a key driver of which hormone causes hair loss in females in younger women.
Hair Trivia
Each hair follicle has its own hormone receptor. Follicles at the crown have more DHT receptors — which is why thinning often starts there first.
03 HOW TO TELL IF HAIR LOSS IS HORMONAL?
Some signs point more clearly to a hormonal cause:
A dermatologist can confirm the cause with blood tests for thyroid levels, iron, and androgens.
- Thinning at the crown or top of the scalp
- Hair shedding spread across the whole scalp
- Hair fall that got worse after pregnancy, menopause, or a stressful period
- Other symptoms like irregular periods, tiredness, or weight changes

04 WHAT HELPS WHEN HORMONES ARE AFFECTING YOUR HAIR?

- Scalp nourishment — a healthier base for follicles
- Root strength — less breakage-related shedding
- Hair density support — better anchoring over time

Clinical Insight
In a 90-day clinical study, the Indulekha Bringha Hair Growth Treatment Serum showed a 43.6% reduction in hair fall from the roots — measured at the follicle level, meaning stronger root hold, not just less breakage.
05 IS A HAIR GROWTH SERUM FOR WOMEN WORTH USING DURING HORMONAL CHANGES?
Yes. Hormonal shifts change the scalp environment - follicles can become more sensitive, oil production may change, and the growth cycle shortens. A targeted serum does not stop the hormonal cause, but it gives follicles the support they need to get through it.
Apply it section by section, directly to the scalp. Massage gently. Leave it on. Repeat daily. Follicles respond to routine - not one-off treatments.

Tip
Apply the serum at the same time each day - ideally at night. Consistency is what makes the difference. Follicles need steady care, not rushed fixes.
06 SMALL DAILY HABITS THAT HELP
A serum works on the outside. Your daily habits support the inside.
Eat iron-rich foods like spinach and lentils. Get enough protein. Keep your sleep regular - it directly lowers cortisol. Gentle movement like yoga or walking helps manage stress hormones. According to DermNet, scalp inflammation and poor nutrition often make hormonal hair loss worse.
None of this needs to be complicated. Small, consistent habits build real results - just like scalp care does.
