My hairline fell out twice, the first time from wearing an instant weave wig. That comb that attaches to your hair will eat your hair up. The second time I had washed my hair with some PM tea tree shampoo and reached for Motions SIlk Protein conditioner and instead it was Motions relaxer. I purchased some hair grease from a woman who received the recipe to make the grease from the Holy SPirit. That grease grew my hair back in less than 7 days. I use it all the time and it is the best thing I've ever used on my hair I honestly believe it was given to her by God and that those that use it will cross her path only because of God. It is called Sunrise Products Added Touch hair pomade. PM me for her phone number. SHe doesn't have a website yet.
