I’ve used this product pretty consistently for about 3 months now and I can say I love this!!! It makes your hair feel so soft and smooth after using it.

The best product for damaged hair. I have to say, the feeling after putting it on is terrible. Your hair looks terrible, but when you wash it after a day or two and you condition your hair, then your hair looks good..
