I do not put OCT on my scalp anymore. After several months of use it started to give me some painful bumps. I was really disapointed because when I used it everday I got an inch per month. I now use it as a overnight pre-poo on my hair and ensure I do not get it on my scalp too much, 2 per week and follow with a deep moisturising conditioner (this is especially important because I am natural) and I am good to go. It makes my hair lush. I can really see the difference when I use it. It is not giving me the growth benefits but it is helping me to retain length. Give me a couple years and I will be sitting on my hair
