I'm also embarking on a personal challenge. I'm using Vaseline to seal my ends. I will discuss the findings on my YouTube channel around Thanksgiving. I'm not encouraging anyone to join me on this rebellious experiment! LOL. I decided to do this after speaking to my 90 year old Grandmother who still uses Vaseline on her natural hair. I will only apply it to the ends and not my scalp or hair strands. Stay Tuned!
