I notice fine hairs growing (on the crown where it is thin) in only a 8 days. I've been using for a month or 5 weeks and there is definitely hairs growing. I can even grip it now!!! Lol, I'm so excited to finally find a product that truly works for me. I've tried som many products so I wasn't expected immediate results. I am now a monthly subscriber and I never subscribe to anything. Thanks for caring and sharing your liquid gold with us!!! Yours truly 😉😊🥰 LOVE IT!!!!
