Not for anyone who has a sensitive nose.
Smooth feel and very moisturizing. Product needs to be washed out of hair and the aroma is over powering to the point where it did not agree with me. I will not buy this again.

I used it , it made my hair feel great but in the morning I find my hair to be dry and it feels like I didn’t put anything on it and as far as hair growth I don’t see it . And it did not make my hair any stronger it’s still breaking .

Wait to see
I am just starting to use it and I have to use it for a couple of weeks to help me know if it’s works but what I notice after applying it to my hair it’s just makes it so smooth and soft
