it was $19.99 at Ulta. I had a gift certif and a coupon for $3.50 off! So I of course I bought a few other things as well. The directions on the NX3 say use daily. I stared last night. I will keep you guys updated.
Ok I broke down and got some on Saturday. It may have had a SLIGHT tingle but didn't really irritate my scalp at all. I'll keep working with it and see if there's any improvment. I just wish it weren't so gall dern expensive.
Ladies don;t expect it to tingle everytime. It never did with me. Sometimes with a freshly washed scalp was when it tingled the worst bordering on itching.
