I’ve gone through chemo twice and my second time growing out this stubborn area just decided no. Just no. When I say I’ve tried everything I’ve tried EVERYTHING. JBCO, hair vitamins, every damn oil out there, scalp treatment. Nothing. Not a single follicle. Shiny bald and annoying. Saw this and was like mmmm okay it’s 10$ what the heck I’ll go for it…this is 3 weeks. And not even every day use. I kid you not. THERES HAIR! Even in the largest spot! I’m sold sold sold. Thank you thank you for such an amazing product! Please never discontinue!!!
