Struggling with sparse or thinning eyebrows? It’s a common frustration, especially when store-bought serums cost a fortune and often deliver disappointing results.
Onion juice for eyebrow growth may sound unusual, but it’s a time-tested natural remedy that’s gaining attention for good reason.
When paired with a nourishing oil, this homemade serum becomes a gentle yet effective treatment you can easily apply at home.
Here’s how to prepare and use this natural blend to bring your brows back to life without harsh chemicals or a long ingredient list.
Maybe You’ve Been Here Too
You’ve plucked too much. The brow serum didn’t work. The pencil fades by lunch. You want something gentle, something you can actually stick with. You’re not alone.
Maybe your brows never fully grew in. Maybe stress or hormones thinned them out. Or maybe you just want a bit more shape without going the cosmetic route.
This is where a natural approach, like onion juice, can offer real results without costing a fortune.
What Most People Don’t Know About Onion Juice
Onions are rich in sulfur, which supports keratin, the protein your hair needs to grow strong. But what matters is the form. The juice from raw, red onion holds the most power, especially when used fresh.
Folk remedies and traditional practices have long used onion juice to stimulate hair growth. What’s less known is how blending it with a soothing oil helps tone down the odor and irritation while boosting results.
5 Benefits of Using Onion Juice for Eyebrow Growth
1. Awakens Tired Hair Follicles
Thinning brows often come from follicles that need a boost. Onion juice increases circulation to the brow area, encouraging new hairs to emerge where growth has slowed.
2. Strengthens Fragile Hairs
Breakage is common when brow hairs are dry or weak. The sulfur in onion juice helps reinforce the structure, making existing hairs more durable and less likely to fall out.
3. Naturally Cleanses the Skin
Its antibacterial properties keep the area around your brows clean, especially helpful if clogged pores or buildup have slowed down growth. You get a healthier environment for new hairs to thrive.
4. Supports Skin Health Underneath
Healthy skin makes a big difference. The antioxidants in onion juice improve circulation and support collagen—important for strong, nourished roots beneath your brows.
5. Blends Easily with Nourishing Oils
Adding castor or coconut oil turns this into a full-on conditioning treatment. The oils seal in moisture, prevent irritation, and help the mixture glide on easily without making a mess.
How to Make Onion Juice Brow Serum at Home
This brow remedy takes only minutes to prepare. All you need is a red onion, some oil, and something to apply it with.
Ingredients
- 1 small red onion
- 1 tablespoon castor oil (or coconut oil)
- Optional: 1 drop vitamin E oil
- Fine strainer or cheesecloth
- Cotton swab or clean spoolie brush
Step-by-step
Step 1: Chop and blend the onion until smooth. Strain the juice through cheesecloth into a clean bowl.
Step 2: Mix one tablespoon of onion juice with the oil. Stir well until blended into a light serum.
Step 3: Clean your brow area thoroughly. Make sure there’s no makeup or residue left.
Step 4: Dip a clean spoolie into the mix. Gently brush across both brows, focusing on sparse areas.
Step 5: Let it sit for an hour or overnight. If the scent bothers you, wipe it off after an hour with warm water and a gentle cleanser.
Step 6: Use daily for 7–10 days, then adjust as needed.
Tip: If the smell is too strong, simmer the onion in water with a black tea bag before blending.
3-Day Mini Challenge
Try it yourself just for three nights. Apply the serum before bed, and see how your brows feel in the morning. Notice any soft hairs coming in? Any less shedding when you cleanse?
Jot down a few quick notes. You may be surprised by what you see after such a small change.
Want to Boost the Results?
Try pairing the onion serum with a weekly brow massage using warm rosemary oil. You can also alternate with aloe vera gel if your skin tends to get dry or sensitive. Both additions give your brows extra support from different angles.
Cautions & Safety Notes
Always patch-test on your inner arm first. Onion juice can be strong, especially on sensitive skin. If you notice stinging or redness, stop using it.
Keep the mixture away from your eyes. Use only a small amount, and never rub it in. If irritation occurs, rinse thoroughly with cool water and wait before trying again.
Those with allergies to onions, skin conditions like eczema, or anyone pregnant or breastfeeding should consult a healthcare provider first.
