Wash your hair as you normally would and ensure it's completely dry before applying castor oil.
Place the castor oil bottle in a bowl of warm water for a few minutes to warm it up. Warm oil is more comfortable to apply and can penetrate the hair follicles better.
Part your hair into sections and use a dropper or your fingertips to apply the castor oil directly to your scalp. Massage the oil into your scalp gently using circular motions.
After applying the oil to your scalp, use a wide-tooth comb or your fingers to distribute the oil evenly through your hair from roots to tips.
For best results, leave the castor oil in your hair overnight. You can cover your hair with a shower cap or towel to prevent the oil from transferring onto your pillowcase.
In the morning, wash your hair with shampoo to remove the castor oil. You may need to shampoo your hair twice to ensure all the oil is removed.
For optimal results, use castor oil for hair growth 2-3 times per week. Consistency is key to seeing improvements in hair growth over time.
