If you mean **Keshai Hair Oil** (sometimes sold as an herbal hair oil), the exact ingredients and formulation can vary by manufacturer. In general, these oils are marketed to support:

* Hair growth
* Reduced hair fall
* Nourishing the scalp
* Improving hair strength and shine
* Helping with dryness and dandruff (depending on the ingredients)

Common herbal ingredients found in many such hair oils include:

* Amla (Indian gooseberry)
* Bhringraj
* Brahmi
* Hibiscus
* Neem
* Curry leaves
* Coconut oil or sesame oil as the base
* Fenugreek (methi)

**How to use:**

1. Apply a small amount to your scalp and hair.
2. Massage gently for 5–10 minutes.
3. Leave it on for at least 1 hour or overnight.
4. Wash with a mild shampoo.
5. Use 2–3 times a week for best results.

**Things to keep in mind:**

* Do a patch test before first use to check for allergies.
* Hair oils can condition the scalp and hair, but they cannot reliably reverse genetic baldness.
* If you have severe hair loss, scalp irritation, or dandruff that doesn't improve, consult a dermatologist.
