For generations, it’s been celebrated as the go-to solution for dry scalp, hair fall and breakage. In fact, one of the biggest reasons for its popularity is the promise of thicker, healthier strands. From social media buzz to grandma’s timeless nuskhas, castor oil for hair growth has been praised for decades.

Benefits of Castor Oil for Hair Growth

Before we dive into the “how-to”, let’s break down why castor oil is such a trusted remedy.

1. Deeply Moisturises the Scalp

Castor oil is rich in ricinoleic acid and omega-6 fatty acids, which are known for their incredible moisturising properties. This helps combat dryness, itchiness, and flakiness, creating the perfect environment for healthy hair growth.

Common Mistakes When Using Castor Oil for Hair Growth

Improves Scalp Hydration

While castor oil for hair can be a game-changer, here are a few pitfalls to watch out for:

  • Using too much oil: More isn’t always better. Overloading your scalp can clog pores and make washing it out a nightmare.
  • Skipping dilution: Castor oil is thick; always mix with a carrier oil for easier use.
  • Not being consistent: Applying it once in a blue moon won’t show results. Regular use is key.
  • Expecting overnight miracles: Like most natural remedies, it takes time—think weeks, not days.
  • Improper washing: Not rinsing properly can lead to build-up, itchiness, and even dandruff.


When it comes to natural remedies, few can match the reputation of castor oil. Whether your concern is thinning, breakage, or simply wanting longer, shinier locks, learning how to use castor oil for hair growth and thickness can truly transform your haircare routine. Pair it with Ayurvedic haircare heroes, stay consistent with your massages, and you’ll soon see why this simple remedy has remained a cult favourite across generations.
