Castor oil works best for dry, frizzy, and thinning hair due to its intense moisturising and strengthening properties. Coconut oil, being lighter, is ideal for normal to oily hair types, providing hydration without weighing hair down or making it greasy.
Final VerdictIf you want faster hair growth and thicker hair, go for castor oil.
If you need lightweight hydration and protection, choose coconut oil.
For best results, use both: coconut oil for deep conditioning and castor oil for scalp treatments.
