How do I use this oil effectively on my hair?

Based on the product's description, Dabur Amla Hair Oil is designed for two primary uses. First, and most commonly, it is intended as a pre-wash treatment. For this, apply a moderate amount to your scalp and massage gently, then work the oil through the lengths of your hair, focusing on areas that feel dry or frizzy. Leave it on for at least 30 minutes, or even several hours, before washing out with your regular shampoo. This allows the oil to soften the hair and create a protective layer. Second, you can use a very small amount (just 2-3 drops warmed between your palms) on towel-dried or dry hair. Apply this sparingly only to the mid-lengths and ends to tame flyaways, add shine, and improve combability without making roots look greasy. Always start with less product than you think you need; you can always add more. If your scalp is sensitive, test a small amount first and discontinue use if any irritation occurs.
