Must have
My hair was very dry and starting to feel like straw from the bleaching. After my first use I noticed a significant difference and my hair felt softer. It looked so much better, with a lot less frizz after blow drying. drying.b I have have 2b

I’m not sure this is worth the money. I’ve used it for a few months now, 6 times consecutively once I got it, then once a week. I apply on damp hair after shampoo and wait 4 minutes, then condition. I can’t use it without conditioner as my hair ends up being extremely stiff. Not sure it did much to repair my hair damage. There are other more affordable options that seemed to give me better results
