I travel a lot for work so my routine needs to be simple enough that I dont forget steps or run out of stuff constantly. This little bottle has been so easy to pack and the dropper means I barely use any each time so it lasts way longer than I expected. About two months of consistent use even with all my travel and my hair still looks fuller and my scalp feels so much healthier despite all the different climates and water types I've dealt with.

Genuinely one of the best hair purchases I've made all year honestly. My crown area looks so much fuller now compared to a few months ago.
