I have thinning hair that is not not growing. The thickening the nuc has been a great help. I see new hair growth and my hair feels thicker and stronger. My hair stylist even noticed the improvement in my hair Read more

Smells like most Aveda products-pretty awesome, however the scent didn't stick around it sort of dissipated when I dried my hair. I've noticed a bit of extra volume. It's not extreme, but there's a bit more fluff in there. I have very fine, silky hair. I sprayed this on damp hair and blow dried as normal. My hair looks great, is not sticky or tacky at all. The sample/trial size of this product is great because it's so easy to try it out before spending $$. I had pretty good luck with this product, it's worth trying if you have fine silky hair like mine. Read more

Aging changed my thick hair to thinning on the top.😞 After reading all the reviews I decided to give this a try. The plus for me… no scent or a sticky/stiff feeling after applying and drying my hair. Downside for me…saw a very oh so slight difference in fullness. Not enough for me to keep purchasing. Read more
