The only negative I have is that there is I wish it came in a larger size!! I really love how soft and manageable this makes my hair feel, the only thing is I have A LOT of hair so I tend to use a lot of this on my wash days. I enjoy the way my hair feels when using. I am obsessed.
10/10!
Hair Type Straight Hair

Hair Type Wavy Hair

FAVORITE HAIR PRODUCT EVER!!!
This made my hair so so soft, no frizz and smells amazing!
