GOLDEN SUNRISE Lakshika,
Maybe Castor oil does not suit you. It is known to reduce natural excess oil from scalp. If your scalp is not oily, it will give you dryness.
So when you choose to mimic any therapy with VK , please choose the right therapy for you.
If you request to ACTIVATE THE SESSION OF HEAD MASSAGE, you may feel the pressure of massage.
If you request the EFFECT OF HEAD MASSAGE, it may give you final effect, in your case its given you dryness in hair.
Thank You
