In my top 5 must haves
This actually works!!!!!! It’s the first thing I use after i towel dry my hair and I wait 4 mins for it to kick in. I can actually feel it penetrating through my damage, my hair legit feels brand new every time I use it and I have severely damaged hair.

Negative zero/ worst ever felt
This product was not meant for me I did hair blond and hair was crunchy on end and I used it made whole head brittle and like straw after first use. However did research for people with gummy hair not people want repair for just smoothness’s.
