This was my first time ever putting anything in my hair. I’ve had virgin hair for 49 years and am about to turn 50! I was covering my Grey hairs with a brush in powder. I hated it because it would rub off every time I accidentally touched it. So tonight I tried it all by myself and was very nervous! It did not have an offensive smell, more like matcha or green tea. I left it in for approximately 3 hours not on purpose but events distracted me from it. Once I rinsed and washed it out I was absolutely shocked!! My grey hair was gone!!! I’m so happy, I have already told 4 people and you should be getting orders from them ASAP! I sent pictures to prove and was asked if it was stinging me and I said no I could not feel anything at all. Very very pleased and I will most definitely be pushing this product big time! My friends trust me and listen to me! They know I would never tell them anything false and only the honest truth! Thank you, Kim Yeo
