Ponytail: Shampoo and condition your hair. Once done, rinse your hair with cold water for a minute. Rinsing it with cool water adds shine and reduces frizz.Apply a quarter-size amount of serum to your damp towel-dried hair to keep your strands smooth. Comb your hair through and pull back as low and high you would like it to be and fix it with a rubber-band (depending on the density you can fix it as tight or lose you want).Then place a segment of hair on the rubber-band to hide it and secure with u-pins. Use a finishing product to fix the look.
