Simmondsia chinensis (seed wax ester)

Jojoba oil

Jojoba oil is a liquid wax that is well tolerated on the skin, but almost none of its popular uses have been properly tested in people. Patch test it first, and do not swallow it.

The best human data is one uncontrolled study of clay-and-jojoba face masks in people with mild acne, where lesion counts fell by about half over 6 weeks. Claims that it grows hair, heals wounds or repairs the skin barrier rest on lab studies, reviews of those studies and tradition.

What it's used for

Evidence is rated per use. The same ingredient can be strong for one thing and traditional for another.

Use	Evidence	What the research shows
Mild acne and blemish-prone skin (clay mask)Compare remedies for skin →	Limited	In an open, uncontrolled study of 194 people using a clay and jojoba oil face mask 2–3 times a week, the 133 who gave complete lesion counts had about 54% fewer lesions after 6 weeks (pustules 7 to 3, comedones 26.5 to 16 on median counts). With no comparison group and a clay in the mask, it cannot show that jojoba oil did the work, and it says nothing about using the oil on its own.^1,2
Dry skin and skin barrier repair	Traditional	Reviews describe jojoba oil as a useful emollient, and one calls its benefits documented preclinically and clinically while also noting discrepancies in the data and questionable study designs. We did not read the underlying human trials, so we rate this on the reviews' own caveats: a plausible moisturiser with little rigorous testing against other oils or plain creams.^4,5,6,2
Hair breakage	Traditional	The only hair-fibre evidence we found is a lab study on locks of hair, not people: adding jojoba oil to a chemical straightening emulsion reduced protein loss and improved resistance to breakage, and was one of the two best conditioning agents tested. It says nothing about everyday use on the scalp or frizz.⁸
Hair growth and hair lossCompare remedies for hair & nails →	Traditional	Jojoba has a folk reputation for promoting hair growth, and reviews repeat it, but we found no trial testing jojoba oil alone for hair growth. In the one randomised trial that used it (86 people with alopecia areata), jojoba and grapeseed oil were the control: they carried thyme, rosemary, lavender and cedarwood oils in the treatment group. The carrier-only group improved in 15% (6 of 41), the essential oil group in 44% (19 of 43).^9,2
Wounds and inflammatory skin conditions	Traditional	In cultured skin cells jojoba liquid wax sped up closure of a scratch wound and stimulated collagen production with very low toxicity. Reviews say it may suit wound healing, skin infections and ageing on that basis, but we found no human wound trial.^7,3,2
Carrier oil for essential oils	Traditional	A lab study of 23 essential oils in six carrier oils found jojoba oil (with aloe vera oil) lowered the cytotoxicity of the essential oils and did not blunt their antimicrobial activity. That is a cell and brine-shrimp result, not a skin-safety trial, and it does not give a safe dilution.^9,10

How much

Ranges below are what studies used and what supplements commonly contain. They are not a recommendation for you. Start at the low end.

Facial mask (studied)

2–3 times a week for 6 weeks¹

The schedule used in the clay and jojoba oil mask study. The abstract does not give the amount of oil or clay in the mask.

Scalp massage (studied)

Daily for 7 months, as a carrier⁹

How long jojoba and grapeseed oil were massaged into the scalp in the alopecia areata trial. The jojoba oil there was the control, not the treatment.

Amount

No evidence-based amount^2,4

None of the sources we read give an amount per application for the oil used alone, so a few drops is a practical choice, not a studied dose.

Timing · The mask study used 2–3 applications a week. No source we read tested a time of day for the oil used alone.With food? · Not applicable; this is a skin product and the sources we read give no basis for swallowing it.How long to trial · The acne mask study judged results at 6 weeks. For other uses we found no studied timeframe, so 4 weeks is a practical checkpoint rather than an evidence-based one.

How people take it

Clay mask with jojoba oil2–3 times a weekThe one form with human data, from an uncontrolled study in mild acne. The study did not test the oil alone or a leave-on product.

Oil applied to skin or faceNo studied amountReviews describe a light liquid wax that stays largely at the skin surface, but we found no trial of the plain oil for acne or dry skin.

Hair or scalp oilNo studied amountLab evidence suggests it may reduce breakage in chemically straightened hair. Use as a hair-growth treatment is unsupported by trials.

Carrier oil for essential oilsDilution not established in our sourcesUsed to dilute essential oils before applying to skin. Follow the essential oil supplier's dilution guidance.

Safety

Who should avoid

Known allergy to jojoba — contact dermatitis has been reported, though rarely
Broken or inflamed skin — patch test first on a small area
Eyes — jojoba oil caused reversible eye irritation in rabbits
Swallowing it — the sources we read give no safe human dose
Pregnancy and breastfeeding — no safety data in the sources we read, so ask first
Replacing prescribed treatment for acne, eczema, psoriasis or alopecia

Known interactions

No interactions in our data. Absence of a flag is not clearance.

Questions people ask

Does jojoba oil help hair grow?

There is no good evidence that it does. We found no trial testing jojoba oil alone for hair growth; in the one randomised trial that used it, in alopecia areata, jojoba and grapeseed oil were the placebo-like control. A lab study on hair locks suggests it may reduce breakage in chemically straightened hair, which is a different claim.

Is jojoba oil good for your skin and face?

It is a well-tolerated emollient, and reviews describe benefits for dry skin and skin barrier repair, but the underlying trials are limited and of questionable design. The best human data is for mild acne, from an uncontrolled study of clay and jojoba oil masks used 2–3 times a week, so it is a reasonable moisturiser to try, not a proven treatment.

Is jojoba oil comedogenic?

None of the sources we read gives a comedogenicity rating or a trial of the oil left on the skin, so we cannot give you a figure. The acne mask study found fewer lesions on average, but the mask was clay and oil together, and it does not show what a leave-on oil would do on your skin. If you break out, stop using it.

How do I use jojoba oil?

Patch test on a small area first. Reviews describe it as a liquid wax that stays largely on the skin's surface, so a few drops on damp skin or hair ends is the usual approach, though no source we read tested an amount. It is also used to dilute essential oils, and it is not intended to be swallowed.
