Hair Care

3 articles

Hair health is a reflection of internal health — and this is one of those areas where the insight of herbal medicine really shines. Hair loss, dull or brittle hair, a dry or oily scalp — these are rarely purely cosmetic concerns. They often signal nutritional deficiencies, hormonal imbalances, thyroid dysfunction, or poor scalp circulation. The herbal approach to hair care addresses both the scalp and hair directly (through topical applications) and the underlying internal imbalances through targeted herbal and nutritional support. The articles here take this whole-body perspective, exploring both the external use of herbs like rosemary and nettle, and the internal use of iron-rich, hormone-balancing, and circulation-supporting herbs.

Hair care through herbal medicine is one of the more immediately rewarding areas of practice — the results are visible, and the herbs involved are largely accessible and gentle. These articles explore both topical applications and the internal herbal and nutritional support for healthy hair.

Frequently Asked Questions About Hair Care and Herbal Medicine

Which herbs promote hair growth?

Rosemary (Rosmarinus officinalis) has recently received significant scientific attention for hair growth — a clinical trial comparing rosemary oil to minoxidil (the pharmaceutical standard for androgenetic alopecia) found comparable efficacy after 6 months. Rosemary is thought to improve scalp microcirculation and inhibit DHT (dihydrotestosterone) at the follicle. Nettle — both topically and internally — is a traditional hair tonic. Horsetail, rich in silica, supports the structural integrity of the hair shaft.

Can nutritional deficiencies cause hair loss?

Very commonly. Iron deficiency is the most frequent nutritional cause of hair loss in women — even when anaemia is not present, low ferritin levels can trigger diffuse hair shedding. Vitamin D, zinc, biotin, and adequate protein intake are also important for hair follicle health. Before investing in topical treatments, it is worth testing iron, ferritin, thyroid, and vitamin D levels.

How do hormones affect hair health?

Androgens (particularly DHT) shrink hair follicles in genetically susceptible individuals, causing androgenetic alopecia (pattern hair loss). Oestrogen prolongs the growth phase of hair follicles, which is why hair often thickens during pregnancy and sheds post-partum. Thyroid hormones regulate the hair growth cycle — both hypothyroidism and hyperthyroidism can cause hair loss. Herbal support for these hormonal drivers is therefore directly relevant.

What topical herbal preparations support scalp health?

Rosemary oil diluted in a carrier oil (jojoba, coconut) massaged into the scalp is well supported by evidence. Tea tree oil addresses scalp fungal issues and dandruff. Aloe vera gel soothes an irritated scalp and provides hydration. Nettle-infused rinse (strained nettle tea used as a final hair rinse) is a traditional tonic for hair shine and strength.

Are there herbs that help with dandruff?

Tea tree oil has antimicrobial properties effective against Malassezia — the fungus most commonly associated with dandruff. Calendula is anti-inflammatory for a sensitive, flaky scalp. Apple cider vinegar rinse can help restore scalp pH and reduce fungal activity.

Can herbal medicine help with hair loss after illness or stress?

Telogen effluvium — diffuse hair shedding that occurs 2–3 months after a significant stressor (illness, surgery, bereavement, post-partum) — typically resolves on its own over 3–6 months as hair follicles reenter the growth phase. Adaptogenic herbs (ashwagandha, rhodiola), iron replenishment if needed, and scalp circulation support (rosemary) can support recovery.
