  • Works great on Fine Thin Hair! I have fine thin hair and this product works perfectly. Not sticky or heavy, just makes my hair appear thicker !

  • Great Product and Fast Shipping: I have an undercut and I have Asian hair which means it is stiff, goes flat and not workable after it drys. This product gave my hair a much needed lift and stays in place after using hairdryer. It is a little sticky like what others have claimed but I like it because it stays the shape I need and with a little clay and hairspray, my hair stays in place and doesn't loose its shape throughout the day.

  • Wow Product. I love Boldify products. I'm 80 years old, yes it's a current picture, and my hair if fine. It takes a lot of products to get body and bounce... as far as making my hair full and lasting I love it.

  • No blow drying needed... this stuff is amazing! I don't need to blow dry my wavy hair for volume anymore!


    Verified Customer Review

  • I LOVE this! I previously used the Adria volumizing spray until I ran out and found this. Voluminous products are essential to me, because my hair is super thin, and straight. It's been a curse (I don't care what you thick, curly haired girls say, haha!) if you have the same trouble/ this product is for you! My hair is in the best shape of its life!
