One of my most frequently-asked questions is how I achieve so much volume at the root of my hair and my secret is this Aveda volumizing tonic. Okay, it’s not a secret. I rave about it constantly because I truly cannot do my hair without it. The problem is, I can go through their tiny 3.4 oz bottles in just a few weeks. So, I was THRILLED to stumble upon this 33.8 oz option on Amazon. If I’ve gotten you hooked on this product and you’re also going through the small bottles like crazy, opt for the big one. You get 10x the quantity for just over twice the price and you can refill the small bottle for on-the-go use.
