I have been using the Tresemmè Keratin Smooth range for a couple of weeks and I am truly a fan of this hair range. I have noticed a difference in the overall condition of my hair. Usually my hair is really dry and frizzy because of it being naturally curly and dyed but this range has really smoothed my hair and adds definition to my curls. I also noticed that my hair has not been falling out as much as it used to. When used for my straight hair routine, the mask and the oil does not leave my hair greasy. I am definitely excited to see the results in the long run.
