Ahem, here goes my best attempt:
Sulfate free shampoos: I found that this was a step in my regi that I didn't know I needed. My hair is much better for it.
Deep conditioner: A couple things here. Please find a quality DC. I have a couple professional brands I swear by. Let me know if you need a recommendation
I spend the most money on my products here.
Also, leave it on for a few minutes. Deep conditioning for the length of a shower will not do enough for most. Atleast it won't do anything for me. Plus my conditioner costs too much to wash out that quick
Protein treatments: Absolutely necessary with relaxed hair. Finding the frequency and strength your hair needs is totally trial and error. Start with the lowest strength with a low frequency. Experimenting in reverse is dangerous
I'll be back later with more.
