Kerasis Heat Primer

It is a no-wash type leave-on treatment, and using it before a curling iron seems to make my hair a bit calmer. The scent is subtle and not overpowering, and since there is a generous amount, it lasts a long time. I recommend it as a great value item. It works even better if you use it with hair essence; it creates a synergistic effect. I am currently on my second bottle.
