Seborrheic Dermatitis: natural remedies and the evidence behind them

Matched a standard antifungal in a scalp seborrheic dermatitis trial

Why this matches

If your seborrheic dermatitis shows up on your scalp, rosemary is one of the few natural options tested directly for this exact condition. In a double-blind trial in people with scalp seborrheic dermatitis, a topical rosemary preparation was compared head-to-head with a standard antifungal lotion.

Why try it

Rosemary (Rosmarinus officinalis) contains rosmarinic and carnosic acids with anti-inflammatory and anti-yeast activity. In a 42-person double-blind trial, a topical rosemary lotion improved scalp flaking about as well as 2% ketoconazole over two months, and eased itching more than the antifungal did. Note the trial used a rosemary extract lotion; rosemary oil products vary in strength and formulation.

Dose or use

Apply a topical rosemary preparation to the scalp as directed; in the trial a rosemary lotion was used twice daily. Dilute rosemary essential oil in a carrier oil before applying and follow product labeling.

Time to results

Typically 4-8 weeks

Key study

Randomized controlled trial (2024, PMID 39652968): Efficacy of Topical Rosemary Extract Lotion versus Topical 2% Ketoconazole Lotion in the Treatment of Seborrheic Dermatitis: A Double-Blind Randomized Controlled Clinical Trial. In 42 people with scalp seborrheic dermatitis, a topical rosemary preparation improved scalp flaking about as well as 2% ketoconazole over two months and reduced itching significantly more than the antifungal.

Caution

For external use only; do a patch test first, as rosemary oil can irritate skin. Consult a healthcare practitioner before use, especially if pregnant or breastfeeding.

Studied in one small trial as an anti-dandruff scalp tonic

Why this matches

One small clinical study assessed lemongrass oil in a hair tonic for dandruff, so it is most relevant if your seborrheic dermatitis is showing up on your scalp. Keep in mind the study was in dandruff, a milder scalp condition, not seborrheic dermatitis itself.

Why try it

A single small clinical study found that a hair tonic containing lemongrass oil reduced dandruff, possibly due to antimicrobial properties that may help control yeast on the scalp. The evidence is preliminary, so treat this as an option that may help rather than an established treatment.

Dose or use

Follow product labeling; consult a healthcare practitioner.

Time to results

Typically 2–4 weeks

Key study

Single small RCT (2015, PMID 26566122): a hair tonic containing lemongrass (Cymbopogon flexuosus) oil reduced dandruff versus placebo; preliminary evidence from one trial, in dandruff rather than diagnosed seborrheic dermatitis.

Caution

For external use only; perform a patch test before applying to the scalp to check for skin sensitivity.

Reduced dandruff versus placebo in a controlled trial

Why this matches

Since your seborrheic dermatitis mostly shows up on your scalp or as dandruff, tea tree oil is one of the better-studied natural options for scalp flaking. A controlled trial tested a 5% tea tree oil shampoo in people with dandruff, the milder, scalp end of the seborrheic dermatitis spectrum.

Why try it

Tea tree oil (from Melaleuca alternifolia) is valued as a natural antifungal thanks to its active compound terpinen-4-ol, which acts against the Malassezia yeast linked to scalp flaking. In one trial a 5% tea tree oil shampoo eased dandruff more than a placebo shampoo, so it is a reasonable option to try on the scalp, though the evidence is in dandruff rather than diagnosed seborrheic dermatitis.

Dose or use

Usually applied diluted in a carrier oil, or used as a shampoo containing tea tree oil; follow product labeling.

Time to results

Typically 4 weeks

Key study

Randomized controlled trial (2002, PMID 12451368): Treatment of dandruff with 5% tea tree oil shampoo. A single-blind, placebo-controlled trial in 126 people found a 5% tea tree oil shampoo reduced dandruff severity versus placebo over 4 weeks. Evidence is in dandruff, the milder scalp form, rather than in diagnosed seborrheic dermatitis.

Caution

For external use only; never swallow it. Dilute before applying and do a patch test first, as undiluted oil can irritate the skin.

Low zinc can worsen skin and scalp flare-ups

Why this matches

If your scalp keeps flaring, it is worth ruling out low zinc — this mineral helps regulate skin repair and immune balance, and a shortfall can show up as scaly rashes and scalp problems.

Why try it

Zinc supports skin barrier function, wound healing and the immune regulation that helps keep skin yeast in check. When it is low, dermatitis and scaly skin are among the early signs, so checking your levels can reveal a fixable contributor.

Dose or use

Ask a healthcare practitioner about testing your zinc level before supplementing; do not self-dose high amounts long-term.

Time to results

Varies; depends on correcting the deficiency

Key study

Educational deficiency guide, not a treatment trial: low zinc is associated with dermatitis and scaly skin rashes, but correcting it is not proven to resolve seborrheic dermatitis specifically.

Caution

Too much zinc can block copper absorption and upset your stomach. Only supplement to correct a confirmed deficiency, under guidance.

Studied as an add-on for facial seborrheic dermatitis

Why this matches

If your flare-ups are mainly on your face, this is worth knowing about: the research on tanshinone looked specifically at facial seborrheic dermatitis. Just note that the studies tested it alongside a prescription steroid, not on its own.

Why try it

Tanshinone, derived from the herb Dan Shen, has been studied as an add-on to conventional treatment rather than as a standalone remedy. In the trials it was taken together with prednisone (a steroid), so it is best thought of as a complement to standard care, not a replacement for it.

Dose or use

Follow product labeling; consult a healthcare practitioner.

Time to results

Typically 4–8 weeks

Key study

Systematic review (2022, PMID 35572959): Tanshinone Capsules Combined With Prednisone for Facial Seborrheic Dermatitis: A Systematic Review and Meta-Analysis of Randomized Clinical Trials.

Caution

Consult a healthcare practitioner before use, especially if taking medications or if pregnant.

Soothing gel for red, itchy, flaky skin

Why this matches

For facial or skin-fold flares that feel red and itchy, topical aloe vera is a gentle, low-risk option to soothe the area — its library entry lists eczema, psoriasis and rashes among what it helps.

Why try it

Aloe vera gel is traditionally used to calm inflammation and hydrate irritated skin, thanks to its soothing polysaccharides. It is a mild choice for taking the sting out of a flare while you address the underlying cause.

Dose or use

Apply a thin layer of pure aloe vera gel to affected skin once or twice daily; follow product labeling.

Time to results

Typically 2-4 weeks

Key study

Traditionally used to soothe inflamed skin; this specific use for seborrheic dermatitis has not been confirmed by a controlled clinical trial cited in our records.

Caution

For external use only. Do a patch test first, as some people react to aloe; discontinue if irritation develops.

Low B2 can cause dermatitis around the face

Why this matches

Because your flare-ups center on your face, low riboflavin is worth ruling out — its deficiency classically causes dermatitis around the face and nose, the same areas seborrheic dermatitis tends to favor.

Why try it

Riboflavin (vitamin B2) helps maintain healthy skin. When it runs low, one of the textbook signs is a dermatitis around the nose and mouth, plus cracks at the corners of the lips — so checking your levels can uncover a nutritional contributor.

Dose or use

Ask a healthcare practitioner about your riboflavin status; B2 is found in dairy, eggs, lean meats and leafy greens.

Time to results

Varies; depends on correcting the deficiency

Key study

Educational deficiency guide, not a treatment trial: riboflavin deficiency is a recognized cause of facial dermatitis, but supplementing is not proven to treat seborrheic dermatitis itself.

Caution

Riboflavin is generally safe, but persistent facial dermatitis should be evaluated by a clinician rather than self-treated.

Low B6 can trigger a seborrheic-type facial rash

Why this matches

With flares mainly on your face, low vitamin B6 is worth considering — its deficiency is a known cause of a seborrheic-dermatitis-like rash around the nose, eyebrows and mouth.

Why try it

Pyridoxine (vitamin B6) supports skin and nerve health. A shortfall can produce a greasy, scaly rash on the face along with cracked lips, so it is a checkable nutritional angle if standard skin care is not enough.

Dose or use

Ask a healthcare practitioner about testing before supplementing; B6 is found in poultry, fish, potatoes and bananas.

Time to results

Varies; depends on correcting the deficiency

Key study

Educational deficiency guide, not a treatment trial: B6 deficiency can cause a seborrheic-type facial rash, but supplementing is not proven to treat seborrheic dermatitis specifically.

Caution

High-dose B6 supplements taken long-term can cause nerve damage. Only supplement to correct a confirmed deficiency, under guidance.

Acupressure point used for inflamed skin

Why this matches

If facial flares are your main issue, LI11 is the acupressure point most associated with calming inflammatory skin conditions, so it is an option you can try alongside your topical care.

Why try it

In traditional Chinese medicine, LI11 (Quchi) — at the outer end of the elbow crease — is used to reduce inflammation and is specifically applied to inflammatory skin conditions like eczema and psoriasis. It is a gentle, self-applied practice to pair with other approaches.

Dose or use

With the arm bent, press firmly on the point at the outer end of the elbow crease for 1-2 minutes; repeat on both arms.

Time to results

Varies; used as an ongoing practice

Key study

Traditional acupressure use; this specific application for seborrheic dermatitis has not been confirmed in controlled clinical trials.

Caution

Acupressure is a complement, not a substitute for skin treatment. Avoid pressing on broken or irritated skin, and skip during pregnancy unless cleared by a practitioner.
