I'm fairly new and have just begun my regimen, but there are a few things I have seen that have made a difference already:
1) moisturize and seal--oh. my. god. this technique is AMAZING. I was VERY skeptical about using EVOO because I had never used oils on my hair. It seemed like such a foreign practice and like it would make my hair greasy. I tried it and the exact same day, I realized the difference in my hair and just how wonderful the ends felt, I was entirely sold on this.
2) Co-Washing: it works great. nuff said.
3) The realization that black hair is dry hair and constantly in need of moisture. I know that this sounds weird, but honestly I never put moisture on my hair and ends daily. It just didn't happen. But now I feel like I better understand how to get moisture and retain it.
