01
What it is
Hanbang is traditional Korean herbal medicine, related to but distinct from Traditional Chinese Medicine. In scalp care, it refers to concentrated herbal extracts – typically decocted or fermented – incorporated into scalp serums, masks, or rinses.
Several of the herbs used have been studied at a pharmacological level in cell and animal research, with some showing measurable effects on inflammation, circulation, and enzymes involved in DHT production. That's a different kind of evidence than a human clinical trial, and the two shouldn't be conflated.
Hanbang is not a substitute for medical hair loss treatment. Framing it as clinically equivalent to minoxidil or finasteride goes beyond what the current evidence supports. It's most accurately understood as a complementary approach, particularly for general scalp maintenance.

Common ingredients
Ginsenosides from red ginseng have been shown in cell-culture and animal studies to increase proliferation of human dermal papilla cells, the cells that help regulate hair growth, along with anti-inflammatory effects. This research is preclinical, not from human trials.
Rich in polysaccharides and triterpenoids with documented antioxidant and anti-inflammatory properties in laboratory research. Used in formulations aimed at sensitive or inflamed scalps.
Camellia seed oil is high in oleic acid, similar to human sebum, and is commonly used as a carrier oil in Korean hair and scalp care with a long history of traditional use.
Widely used in Korean scalp care. Compounds in mugwort have documented antibacterial, antifungal, and anti-inflammatory effects in laboratory studies. Commonly used for sensitive, reactive, or dandruff-prone scalps.
A 2002 study found that Sophora flavescens root extract inhibited type II 5-alpha-reductase activity in a laboratory assay and promoted the growth-phase transition in mice. This was the whole extract, not an isolated compound, and 5-alpha-reductase inhibition in this kind of assay doesn't guarantee a meaningful effect on human DHT levels or hair loss.
03
What the experience is like
A session typically begins with a consultation and often a scalp camera assessment, followed by application of herbal formulas selected for the scalp condition, scalp massage with herbal oils, and sometimes steam with an herbal infusion. Neck and shoulder work is often included.
Sessions commonly run 60 to 90 minutes. The experience tends to be more spa-like than a standard clinical scalp session, with herbal scents and oils as part of the format.

Limitations & considerations
- Most research on the individual herbs used in hanbang scalp treatment comes from cell-culture or animal studies, not large human clinical trials. Promising laboratory findings don't guarantee the same effect in a person's scalp
- A finished hanbang formula typically combines several herbs. Evidence for one ingredient studied in isolation doesn't establish the effect of the blended product actually used on a given scalp
- Hanbang is not a substitute for physician-managed treatment of significant hair thinning. Where hair loss is a concern, a dermatologist's evaluation is worth pursuing alongside, not instead of, hanbang scalp care
- Herbal ingredients can interact with medications or cause allergic reactions. It's worth telling the clinic about any medications or known sensitivities beforehand
- Product standardization varies widely between providers – concentration, sourcing, and preparation are not consistent across the industry, so evidence for one formulation doesn't transfer automatically to another
- No specific outcome, including hair growth or reduced shedding, can be guaranteed
Evidence note
A 2015 study by Park and colleagues found that red ginseng extract and the ginsenoside Rb1 increased proliferation of human dermal papilla cells in culture, and promoted hair growth in mice, through effects on cell-signalling pathways involved in hair follicle activity. This is laboratory and animal research, not a human clinical trial of a scalp treatment.
A 2002 study by Roh and colleagues found that Sophora flavescens root extract inhibited type II 5-alpha-reductase activity in a laboratory assay using rat prostate tissue, and promoted an earlier shift from resting to growth phase when applied to mice. The study examined the whole extract rather than isolating a single active compound, and it did not test the extract in humans.
Taken together, this research supports the idea that some hanbang ingredients have biologically plausible mechanisms relevant to hair and scalp health. It does not establish that any specific commercial hanbang scalp treatment produces a measurable effect on hair growth or loss in people, since none of the cited research tested a finished commercial product on human scalps.
