Another suggestion is to wipe away excess oil from your scalp using a cotton ball dipped in witch hazel. Get in touch with the Hair Transplant Clinic Rajouri Garden, which provides excellent services at reasonable costs. Only once or twice a week should you oil your hair. You don't need to leave it on much longer than that, but leave it on for about an hour or two. Because oil will flow down onto your skin if you keep it on too long, you run the danger of developing zits, and there is no real added advantage to doing so.
