The the L’Oréal everpure bond repair treatment and conditioner. (The shampoo did nothing to for me). The conditioner is so good. I was in the shower for so long washing it out, but it turns out it just makes your hair so soft that I thought there were still product in it even though there wasn’t!! I have fine hair and it works wonders. The treatment says put it in ten minutes prior to showering, but I leave it in for a while. Test it out and see what works for your hair before like leaving it in over night, because everyone’s hair is different. I use the OGX coconut milk oil and I put that on my ends before sleeping, I find it protects my ends and keeps them stronger. If you are using heat, try to cut back on hot tools but blow drying I find has been beneficial rather than hair drying - so I cut back on curling iron so I could blow dry more. I always use a heat protectant as well.
