Even though so many people on the interet were suggesting K18I was unsure if that would really help do something to my hair. Surprisingly it work. You can feel the difference in the elasticity of your hair after three applications. It does not help with hair texture. It works only on the structure. I am not sure how people are able to cover their enture hair in 3 pumps, but i found that difficult trying my best not to use a lot as per the directions so i section my hair in 4 and then apply 4 but smaller pumps
