Here’s what’s actually true:
Castor oil: Commonly used as a laxative, moisturizer, and in some hair/skin treatments.
Apple cider vinegar (ACV): Often used as a food ingredient or for topical home remedies, though its acidity can irritate the skin.
Mixing them: The two substances don’t chemically react in a dangerous way when combined. However, applying them to the skin can cause irritation, redness, or rash in sensitive individuals, especially due to ACV’s acidity.
⚠️ The red patch shown in the image is likely skin irritation, not an “irreversible reaction.”
If you were looking for an actual recipe with these two ingredients, people sometimes mix them in DIY hair masks or skin care blends:
✅ Example (for hair/scalp):
2 tbsp castor oil
1 tbsp apple cider vinegar (diluted with equal water)
Massage into scalp, leave for 20–30 minutes, then wash thoroughly.
This is said to balance scalp pH and condition hair, but results vary. Always do a patch test first to avoid irritation.
