 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

I’ve been using this product since I first bleached my hair, and it’s been amazing. It helps prevent my hair from turning into a ratty mess and keeps it manageable and healthy. My hair doesn’t feel dry or straw-like anymore. It is a bit pricey, but absolutely worth it — I’d rather spend on one product that truly works than waste money on several that don’t deliver the same results.
