Hair Renewed
Smells like fresh coffee very nice, it makes your hair baby soft and smelling good. I'm so glad I purchased this I use it once a week. I really see 👀 and feel the difference in my hair, I put and leave it in for 30 minutes after time ⏲️ up I massage 💆♀️ my head for 2 or 3 minutes then comb through my hair then shampoo and condition.

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.
