Problem : Excess sebum hardens and builds layers of deposits on your scalp to choke off your hairs and make growing hair extremely hard.

Solution : Dab and rub olive oil all over your head before you go to bed. Sleep with it on your head the whole night and shampoo it out in the morning.

So, why do I have you do this? Olive oil helps to break up those hardened layers and eliminate bacteria for healthier hair growth.
