I used this when my hair is almost dry and i brushed to apply all the product. I used with the mask as well and this helped me to maintain the color longer. I purchased mine from ulta

I purchased this during a sale at Ulta. The product bottle is so cute and easy to use. I did shake well before applying as the product separates. At first the product smells good on wet hair, but after it dries it smells terrible. It was pungent enough to make me gag. It didn’t really work on making my hair hydrated either. I did return.

Wow! I am really impressed with this Seal and Protect leave- in (The Perfect Blonde)! One use and my hair was transformed. I have platinum hair, mostly. My ends had gotten rather brassy looking, leaving me sort of two-toned. (Three if you count the 1/4 inch root regrowth) and I desperately needed something to brighten up the ends but if I bleached them my hair would definitely have begun to break off so that was off the table. I got a bag of hair samples from a $50 Ulta purchase and this was in it. So I followed the instructions by spraying from root to ends and I did it in sections so I covered everything. To my amazement when my hair dried, it looks like I just freshly bleached it! Other than my regrowth it's all a pretty platinum blonde that's both bright and shiny. My hair is really soft too. Definitely recommend for blondes
