My very 1st order included the Hair grease and the night serum. It's only been 15 days 6/1-6/15) and I seen growth in the temple area of my hair and along the edge. I grease my scalp in the morning and plait or cornrow my hair. At night, I put the serum in the parts and near the temples along the side. I wear a bonnet. In TWO DAYS, I noticed some growth along the edge. Yes I feel the tingling and itchiness. I put very little grease because my hair is thirsty. I decided to only use the serum the edges and in area of temples as well in the back center of my head which isn't as long as the rest of my hair. I think because I wore a cap a lot. I've ordered edge control, argan oil and more night serum. I only told one person that I was using this product. I'm waiting. It's only been a 15 days in this journey. Looking forward to getting my edge control!
