Beetroot is generally safe for hair, but it can cause side effects. The most common ones are temporary pink or red staining on light hair and scalp, itching or redness from a beet allergy, dryness when mixed with lemon juice, and stomach upset or kidney-stone risk if you drink large amounts daily. Patch test first, and rinse well.
Scroll TikTok or Pinterest for five minutes and you’ll find someone blending raw beets into a hair mask, promising thicker strands and a redder shine. The logic isn’t crazy. Beets carry folate, manganese, potassium, vitamin C, and dietary nitrates, and your hair follicles do rely on steady blood flow and nutrients to grow.
Here’s the part most of those videos skip: there are no clinical trials showing that beetroot juice or beetroot masks regrow hair in humans. The benefits are theoretical. The side effects, on the other hand, are things real people report all the time – usually after they’ve already stained a white pillowcase.
This guide covers what can actually go wrong, who’s most at risk, and how to use beetroot without regretting it.
This is the number one complaint, and it’s not an allergy or a health problem – it’s chemistry. Beets get their color from betalains, a group of water-soluble red-violet pigments. Porous hair grabs pigment fast.
You’re most likely to see staining if your hair is:
The tint usually reads as a pink or reddish cast rather than a true dye job, and it typically fades over 2–6 washes. Clarifying shampoo speeds it up. On dark brown or black hair, you’ll rarely notice anything.
Also stains: your scalp, hairline, ears, nails, towels, and shower grout. Wear gloves. Use an old towel.
Raw beet juice is mildly acidic and contains compounds that some skin simply doesn’t like. Leaving a mask on for an hour “for better results” is the usual trigger.
Watch for:
If your scalp is already compromised – eczema, psoriasis, seborrheic dermatitis, or fresh scratches – the risk goes up sharply. So does it if you just colored or relaxed your hair.
Beet allergy is uncommon, but it exists. Reactions have been documented to betalains and to beet proteins, and they can show up on the scalp as hives, swelling, or intense itching. People with an existing allergy to other members of the amaranth family – spinach, chard, quinoa – may be slightly more prone.
Stop immediately and call a doctor if you notice swelling of the face or lips, trouble breathing, or hives spreading beyond the application area. That’s not a “wash it out and see” situation.
Most viral beetroot hair recipes tell you to add lemon juice or apple cider vinegar to “activate” the color. Lemon juice sits around pH 2 to 3, which is far more acidic than your scalp’s natural range of roughly 4.5 to 5.5.
Used weekly, that combination can:
Beetroot on its own is far gentler than beetroot plus citrus.
Pulp is the problem. Grated beet or thick puree is genuinely hard to rinse out, and leftover residue can sit at the roots, mix with sebum, and lead to flaking, clogged follicles, or that dull, coated feeling. Strain your juice through a fine mesh or cheesecloth before it goes anywhere near your head.
Beets are a high-oxalate food. In people prone to calcium oxalate kidney stones – the most common stone type in the U.S. – a daily beet juice habit can meaningfully raise urinary oxalate.
This matters for hair in an indirect way too: oxalates bind minerals like calcium, iron, and zinc in the gut, and iron and zinc deficiency are both linked to hair shedding. So the “drink beet juice for hair growth” advice can quietly work against you if you overdo it.
If you have a history of kidney stones, talk to your doctor before adding daily beet juice.
An estimated 10 to 14 percent of people experience beeturia – pink or red urine after eating beets. It’s harmless and it passes. It can, however, be a flag for low iron status, which is worth mentioning to your physician if it happens consistently.
Large amounts of beet juice can also cause gas, cramping, or loose stools, mostly from the fiber and fermentable sugars.
Beets are rich in dietary nitrates, which the body converts to nitric oxide. That’s why athletes drink beet juice – it widens blood vessels. Research shows modest reductions in systolic blood pressure, generally a few points.
That’s helpful for many people and a problem for others. Use caution if you:
Dizziness while standing in a hot shower with a beet mask on your head is not the hair care experience anyone signed up for.
Not a physical side effect – but arguably the costliest one. If your shedding is caused by androgenetic alopecia, thyroid dysfunction, iron deficiency, postpartum hormone shifts, or a medication, beetroot won’t touch it. Months spent on kitchen masks are months not spent on treatment that works, and some hair loss is easier to slow early than reverse later.
See a board-certified dermatologist if you’re losing more than about 100 hairs a day, seeing a widening part, or noticing patchy loss.
| Side effect | Most at risk | How to reduce it |
| Pink/red staining | Blonde, gray, bleached, high-porosity hair | Strand test; limit to 15–20 min; clarify after |
| Scalp irritation | Eczema, psoriasis, recently colored hair | Patch test 24 hrs; dilute with aloe or yogurt |
| Allergic reaction | Amaranth-family allergies (spinach, chard, quinoa) | Patch test; stop at first sign of hives |
| Dryness, breakage | Curly, fine, color-treated hair | Skip lemon juice; deep condition after |
| Kidney stones | Personal or family history of stones | Limit juice; ask your doctor |
| Low blood pressure | People on BP or nitrate medication | Keep intake moderate; monitor |
| Residue and flaking | Thick, dense, or low-porosity hair | Strain the pulp; rinse thoroughly |
Stop using it if you notice burning, spreading redness, hives, increased shedding, or a rash that lasts more than a day or two.
No. Beetroot is not a permanent dye. It deposits a temporary pink-red tint that typically fades within 2 to 6 washes. It fades faster with clarifying shampoo and is barely visible on dark hair.
Beetroot doesn’t directly cause hair loss. Indirectly, very high intake may reduce absorption of iron and zinc because of its oxalate content, and both minerals matter for healthy hair growth. Normal food amounts are not a concern.
For most healthy adults, a small daily glass is fine. Avoid daily intake if you have kidney stones, low blood pressure, or take blood pressure medication. Check with your doctor first.
Fifteen to twenty minutes is enough. Longer sessions increase staining and scalp irritation without adding benefit.
Yes, often noticeably. Gray and white hair is porous and picks up pigment easily, sometimes leaving an uneven pink cast. Always strand test first.
Yes. Raw beet juice is mildly acidic and can trigger stinging, redness, or itching, especially on skin with eczema, psoriasis, or recent chemical treatment.
There’s no clinical evidence that beetroot regrows hair. Its nutrients support general health, which supports hair health, but that’s not the same as a proven hair growth treatment.
Wash with a clarifying shampoo, then use a gentle exfoliant or micellar water on stained skin. Most staining lifts within a few washes on its own.
Beetroot isn’t dangerous for your hair. It’s just oversold. Used once a week, diluted, strained, and rinsed within 20 minutes, most people will be fine – the worst outcome is usually a faint pink tint and a ruined towel. The people who need to be genuinely careful are those with light hair, sensitive or inflamed scalps, a beet allergy, a kidney stone history, or low blood pressure.
And if you’re chasing beetroot because your hair is thinning, please get the cause diagnosed first. That single step will do more for your hair than any vegetable in your kitchen.
