 my favorite one 
I have bleach hair and I’m using a couple times is my third bottle but I love it I will keep buying and keep using on my hair because my hair with this product now is softer. My ends are not split anymore

HOLY GRAIL
Omg if I could give this product 10 stars!!! I recently got a balayage, I’m a natural brunette & of course with any bleaching there will be some damage to your hair. I purchased this to help keep my hair as healthy as I could. Safe to say, my hair has been looking so good! My hair is soft, looks hydrated, and I’ve definitely kept it healthy as much as possible.
