Growing your hair like Rapunzel within months takes more than a miracle. Taking your daily dose of vitamins and or applying hair growth serums are two essential keys to gaining your desired length. Not only are you keeping your hair nourished with the essential oils needed to prevent dandruff, but you are moisturizing your scalp. Buying the right products for your hair type is really important. The thinner your hair is typically the less oil needed. If your hair is thicker, then having a thicker growth serum or more oil applied will help with growth.
