Chamomile tea has genuine benefits for hair, backed by a growing body of research. Its key compound, apigenin, has demonstrated anti-inflammatory, antioxidant, and even hair-growth-promoting properties in scientific studies. Whether you’re looking to calm an irritated scalp, add subtle highlights, or support thicker growth, chamomile offers something real, though with important caveats about what the evidence actually shows.
How Chamomile Supports Hair Growth
The most promising research centers on apigenin, a flavonoid found abundantly in chamomile flowers. In a 2024 study published in Food Science & Nutrition, researchers applied apigenin topically to mice with hormone-driven hair loss (the same type that causes male and female pattern baldness in humans). After 28 days, hair regrowth in the apigenin group matched that of the minoxidil group, a standard hair loss treatment. The compound appeared to work by activating a signaling pathway called Wnt, which plays a central role in hair follicle cycling and new growth.
What made the findings particularly notable: apigenin increased the expression of genes related to blood vessel formation and stem cell maintenance more effectively than minoxidil did. Better blood flow to the scalp means more nutrients reaching hair follicles, which is one reason minoxidil works in the first place.
A six-month human clinical trial, published in Cogent Medicine, tested chamomile extract (Matricaria chamomilla) alongside standard hair loss treatment. Participants who used chamomile extract in combination with minoxidil saw significantly greater improvements in terminal hair count and patch size compared to those using minoxidil alone. The researchers described “remarkable synergism” between the botanical extract and conventional treatment. This is encouraging, but it’s worth noting that chamomile extract was used as a complement to medical treatment, not a replacement.
Calming an Irritated Scalp
Chamomile has been used for centuries to soothe skin, and modern research supports this traditional use. A comprehensive review in the journal Pharmaceuticals confirmed chamomile’s anti-inflammatory and anti-itch properties. In animal studies, chamomile essential oil reduced scratching behavior in a dose-dependent way, meaning higher concentrations worked better. Topical chamomile oil also significantly reduced the severity of skin lesions in atopic dermatitis models.
For your scalp, this translates to potential relief from itching, flaking, and redness. A chronically inflamed scalp can disrupt hair growth cycles, so keeping inflammation in check is one indirect way chamomile may help you maintain healthier hair. If you deal with a dry, itchy scalp that isn’t caused by an underlying condition like psoriasis, a chamomile rinse is a low-risk option to try.
Natural Hair Lightening
Chamomile’s lightening effect is real but subtle. Apigenin and other flavonoids in the tea deposit a faint golden pigment on hair strands, and sunlight activates this process. The result is a gradual, warm-toned lift rather than anything dramatic. Think sun-kissed highlights, not bleach.
The key ingredient in this equation is UV exposure. Applying chamomile tea to your hair and staying indoors won’t do much. You need to let your hair dry in direct sunlight for the flavonoids to interact with your hair’s natural pigment. Adding a squeeze of lemon juice speeds up the effect because the acid opens the hair cuticle slightly, allowing more pigment interaction.
If you have dark brown or black hair, don’t expect chamomile to turn you into a blonde. On brunette hair, repeated applications can create a warmer, slightly lighter tone over time. One popular method: combine a quarter cup of strong chamomile tea with a quarter cup of apple cider vinegar and some lemon juice, spray it through your hair, and leave it in overnight or while spending time outdoors. On naturally light or medium brown hair, the results are more noticeable.
How to Make a Chamomile Hair Rinse
The simplest approach is a post-shampoo rinse. Steep four or five chamomile tea bags in two cups of boiling water and let the mixture sit for at least 30 minutes to extract as much apigenin as possible. Let it cool to a comfortable temperature. After shampooing, pour the rinse slowly over your hair, working it through from roots to ends. You can leave it in for up to 30 minutes before rinsing with cool water, or leave it in entirely if you’re heading outside and want the lightening effect.
For scalp soothing, focus on massaging the tea into your scalp rather than just coating the hair shaft. Cool or lukewarm tea feels better on irritated skin than warm tea. You can do this two to three times a week without worrying about buildup or damage, since chamomile tea is essentially flavored water with dissolved plant compounds.
Loose chamomile flowers, available at most health food stores, produce a stronger brew than bagged tea. Use about two tablespoons per cup of water if you go that route.
Who Should Be Careful
Chamomile belongs to the Asteraceae family, which includes ragweed, mugwort, and chrysanthemums. If you’re allergic to any of these plants, chamomile can trigger a reaction. A case report in the Journal of Allergy and Clinical Immunology documented a severe anaphylactic reaction in a child who drank chamomile tea, traced to cross-reactivity between chamomile and ragweed pollen. Topical use carries less risk than ingestion, but if you have known pollen allergies in this plant family, do a small patch test on your inner arm before pouring chamomile tea over your scalp.
What Chamomile Can and Can’t Do
The honest picture: chamomile tea is not a hair loss treatment. The animal studies on apigenin are compelling, and the one human trial showed real benefits, but only when chamomile was combined with a proven medical treatment. A brewed tea also contains far less concentrated apigenin than the extracts used in research. Pouring chamomile tea on your head delivers some of the compound, but not at clinical levels.
Where chamomile genuinely delivers is as a gentle, no-downside addition to your hair care routine. It can soothe mild scalp irritation, add subtle warmth and brightness to your color, and provide antioxidant protection to hair and scalp tissue. For people already using evidence-based hair loss treatments, chamomile may offer a complementary boost. On its own, it’s a pleasant rinse with real but modest benefits, not a miracle cure.
