Home remedies for eyebrow growth: castor or coconut oil, a brow brush and a break from threading
Years of threading and plucking, or naturally sparse brows, can leave gaps that are slow to fill. These home remedies for eyebrow growth give brows the best chance: a dab of castor or coconut oil at night, daily brushing with a clean spoolie, a long break from threading and a diet with enough protein and iron.

Why eyebrows thin
Over-plucking, threading and waxing can damage follicles over time. Ageing, thyroid problems, iron deficiency, eczema and alopecia areata can also thin the brows, especially the outer third. Brow hair grows slowly, so changes take at least two to three months to show.
In Indian homes, castor oil and coconut oil have long been applied to brows and lashes as a conditioning ritual.
Ingredients
- A few drops of cold-pressed castor oil or virgin coconut oil
- A clean spoolie brush or a clean cotton bud
- Protein and iron-rich foods
How to prepare
- Pour a few drops of oil into a clean small container.
- Wash and dry the brow area before bed.
How to use
- At night, apply a very thin layer of oil along the brows with the spoolie or cotton bud and brush in the direction of growth.
- Brush brows daily for a minute.
- Stop threading, plucking and waxing for at least 3 months while the brows regrow.
Helpful habits
- Use a brow pencil or powder to fill gaps meanwhile.
- Wash off heavy brow makeup every night.
- Check thyroid and iron levels if thinning is sudden or the outer brows are disappearing.
Precautions
- Keep oil out of the eyes; if it enters, rinse with clean water.
- Patch test castor oil on the inner arm first.
- See a doctor or dermatologist for sudden brow loss, patchy loss or loss with other symptoms.
Frequently asked questions
How can I grow my eyebrows back naturally?
- Stop plucking and threading, apply a little conditioning oil at night, brush daily and give it three months or more.
Does castor oil help eyebrow growth?
- Castor oil is a traditional brow conditioner. It may make brows look fuller and healthier, but strong scientific evidence for regrowth is lacking.
Why are the outer parts of my eyebrows thinning?
- It can be due to ageing, over-plucking or sometimes an underactive thyroid. A simple blood test can check thyroid function.
