The theory goes that the hairs' natural oils are meant to stay in your hair and stripping them away with shampoo (to replace with chemical conditioner) only aggravates the amount of oil produced so our scalps produces more than is necessary to fight back the shampoo and we're left with no choice but to stick to shampooing to wash away the excess oils.
The theory claims that if we stop putting harsh chemicals on our scalps for 6 weeks the hairs’ natural balance of oils is restored, your scalp stops producing excess oil and only the amount neccesary and your hair becomes healthier, cleaner and more attractive than ever before.
